v2.1.271

What's changed

Added fast mode in Claude Code Remote sessions (cloud and self-hosted runners): the host's fast-mode setting or /fast typed in the session applies where your organization allows it
Added mouse support to the /config panel in fullscreen mode: the wheel scrolls the settings list, a click on a setting's value changes it, and the row under the pointer is highlighted
Added claude self-hosted-runner --drain-marker-file <path>: when that file exists at a SIGTERM drain, the runner reports its exit to the server as a host drain (telemetry only)
Added per-command allowed_domains to Bash, PowerShell and Monitor in auto mode with sandboxing: the hosts a command needs are reviewed with it and opened for it alone; other hosts are refused
Added omitClaudeMd to agent frontmatter and --agents JSON, letting custom and plugin subagents run without user, project and local CLAUDE.md files; managed policy files still load
Added --accept-command <sha256> to claude plugin install and claude plugin update to accept exactly the command a previous --json run displayed, instead of -y
Added support for a multiplier above 1, up to 10, in the modelPricing managed setting and the Claude apps gateway pricing block, for marked-up internal chargeback rates
Added a spinner tip pointing Bedrock, Vertex AI, Foundry and LLM gateway users to the Claude desktop app; the claude.ai desktop app tip now suggests /desktop, which offers to download the app
Fixed a cached organization policy being reused after switching accounts, organizations, or API keys, and the policy not refreshing until the hourly check when the credential changes mid-session
Fixed the tool and command lists not updating when the organization policy finishes loading after startup or changes mid-session
Fixed an enterprise managed-mcp.json that can't be read or parsed being ignored: it now keeps exclusive MCP control (user, project and plugin servers don't load) and warns at startup
Fixed org policy being fetched through, and rejected by, third-party local proxies set via ANTHROPIC_UNIX_SOCKET; they are again treated like other custom gateways, including for Remote Control
Fixed cloud sessions rejecting every subagent tool call ("updatedInput … failed schema validation") when a workflow or agent approval was applied after the session's worker restarted
Fixed /fast off answering "Fast mode unavailable" instead of turning fast mode off when the organization has fast mode disabled
Fixed sessions started with CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK re-sending fast requests every turn after the API rejected fast mode; the rejection now stands and its reason is shown
Fixed fast mode under CLAUDE_CODE_RETRY_WATCHDOG failing the turn on a usage-credits limit, or retrying an overload at fast speed, instead of falling back to standard speed
Fixed Bash permission checks missing the file that fmt, column and similar commands read when it follows an option the checker doesn't recognize
Fixed Bash permission checks skipping files a wildcard expands to when the wildcard sits in a command's pattern or option value (for example grep -v dir/* file)
Fixed Bash permission checks so that shell variable declaration flags cannot misrepresent the command being run
Fixed Bash commands with two directory changes, a subshell, or a cd+git chain skipping the prompt under permissions.blockReadsOutsideWorkingDirectories in bypass and auto mode
Fixed a stale .git/config.lock breaking git checkout -b, git push -u and git config for the rest of a session after a sandboxed command failed to start (Linux)
Fixed settings file changes made outside the session going unnoticed on macOS machines whose system file-event service is saturated; the watcher now falls back to polling
Fixed resumed claude -p sessions whose tools all come from MCP servers failing with "At least one tool must have defer_loading=false"
Fixed turns failing with "API returned an empty or malformed response" when an LLM gateway returns the non-streaming reply as text/plain
Fixed sustained high CPU usage and repeated tool-list requests when an MCP server sends list_changed notifications in a tight loop
Fixed MCP OAuth mishandling client registrations: denying consent forced a new one, one for another redirect URI was reused, and a concurrent write could delete a valid one or keep a mismatched one
Fixed tool search returning no match when Claude selects an MCP tool by its bare name instead of its full mcp__server__tool name
Fixed Ctrl+O cancelling pending MCP server reconnects, and /mcp sent from Remote Control failing while the transcript view is open
Fixed the Claude in Chrome prompt telling the model to load tools through ToolSearch when ToolSearch is unavailable
Fixed cross-session messages held by the receiving session's permission-mode policy leaving no trace: headless senders now get a delivery notice, and SendMessage results no longer imply it was read
Fixed Claude starting a second copy of a background command (such as a watch task or dev server) that was still running after the conversation was compacted
Fixed /model warning about losing the conversation cache when switching back to the model the conversation actually ran on
Fixed /reload-skills reporting a skill count that disagreed with the slash menu after /cd
Fixed /resume and /continue showing only 1-2 sessions in fullscreen mode on short terminals
Fixed /resume and /teleport keeping the previous conversation's file-read tracking, so Claude could edit files the resumed conversation had never read
Fixed --resume dropping the 1M context window ([1m]) when the resumed session's model family differs from the configured default model
Fixed artifacts attached with /artifacts disappearing from the session after --resume
Fixed background sessions (claude --bg, claude agents) not watching the artifacts they publish for republishes made elsewhere
Fixed custom agents, slash commands and output styles beyond the first not loading from a virtual drive that reports inode 0, such as an encrypted vault mounted as a Windows drive
Fixed self-hosted runner sessions silently losing all host config (settings, skills, plugins, MCP servers) when the host config directory exceeds 64 MiB; added --host-config-snapshot disk|memory
Fixed skills synced from claude.ai staying on disk indefinitely after signing out; copies not refreshed within cleanupPeriodDays now move to the recoverable trash at the next launch
Fixed spinner tips suggesting commands that aren't available for your account type or are disabled in your session
Fixed the /add-dir path input: the left and right arrow keys now move the cursor, and Enter adds only the typed path instead of also adding the highlighted completion
Fixed text fields outside the main prompt moving a leading ! to the end of what you typed (!foo came out as foo!)
Fixed the interactive /hooks menu crashing when a hook matcher is named after an inherited object property such as __proto__ or constructor
Fixed a fullscreen rendering glitch where text kept a stale background color after the box around it lost its background
Fixed Delete in st and Alt+arrow keys in rxvt-unicode not working in attached background sessions
Fixed the terminal's replies to capability queries (^[[?1;2c) appearing at the shell prompt or in an editor when Claude Code exits, is suspended, or opens an editor right after starting
Improved terminal rendering performance: large diffs and long transcripts render faster, with fewer slow frames
Improved startup time slightly by skipping a redundant validation of built-in model data on every launch
Improved hook feedback: while a SessionStart, UserPromptSubmit, PreToolUse or SessionEnd hook runs, the spinner says so with elapsed time, and Esc cancels a prompt waiting on a SessionStart hook
Improved the spinner status during long thinking: it now reads "deep in thought" after 45s, and shows "picking the thought back up" while recovering from the output-token limit
Improved dynamic workflows to pause when you hit your usage limit and continue automatically when it resets, instead of dropping the affected agents
Improved Remote Control to leave fewer empty sessions on claude.ai when setup fails on a flaky network
Improved the Claude in Chrome message in cloud sessions when the browser can't be reached: it now says the computer may be asleep before it suggests an install
Improved claude mcp serve: a running tool call now sends a progress update every 30 seconds, so clients show it is still running and idle timeouts don't abort a long command that prints nothing
Improved Foundry and Claude Platform on AWS sessions: an alwaysLoad MCP server that finishes connecting mid-conversation is usable on the next turn without a tool-search round trip
Improved Markdown files published as artifacts: they now render as styled document pages (title header, document typography, syntax-highlighted code)
Improved Artifact tool publish errors: a publish with no file now says to write the page to a file first, and an unsupported file type is reported before a missing favicon
Improved the Artifact tool's error when a page declares a capability its contract version lacks: it now lists every supported capability and notes when a newer contract version has it
Improved artifact watching: a session can now watch up to 10 published artifacts at once for republishes made elsewhere, up from 5
Improved PDF @-mentions to say "page count unknown" instead of a page count guessed from the file size when pdfinfo cannot count the pages
Improved /mobile to show a single QR code for claude.ai/mobile, which opens the right app store for your phone
Changed auto mode so that a skill's or slash command's inline ! shell commands follow default-mode permission rules instead of the classifier; a command no rule decides runs as a reviewed tool call
Changed auto mode so a subagent reports back to its caller through a dedicated hand-back call that the safety classifier reviews, instead of its last message being reviewed after the fact
Changed Monitor watches to always have a deadline (at most 30 minutes; 10 in single-prompt -p runs) and notify Claude to re-arm, replacing the no-timeout persistent option
Changed the IDE selection indicator in the prompt to a [⧉ …] pill that wraps with the text instead of squeezing multi-line prompts; delete it with Backspace to leave the selection out
Changed the default dynamic workflow size to small on Pro plans and lowered the medium size guideline from 15 to 10 agents
Changed Claude apps gateway, Bedrock, Vertex AI, and Foundry sessions so that they no longer refresh a leftover claude.ai login that the session does not use
Updated the bundled claude-api skill to enable eager_input_streaming on streaming custom tools, and to start deliverable-shaped Managed Agents work with user.define_outcome
[VSCode] Added an Attach Open File setting that, when turned off, stops the open file from being added to messages; selected text is still attached
[VSCode] Fixed the Hooks and Permission rules dialogs reporting a save that landed as failed, and the Hooks dialog going blank under a plugin-only policy lock or showing color codes in save errors
[VSCode] Fixed Hooks dialog saves: no duplicate hook on replace, a header name retyped in other capitals keeps its secret, and settings.local.json is gitignored before the save returns
[VSCode] Fixed session history showing only the current session when the workspace is on a Windows mapped network drive or SUBST drive
[VSCode] Fixed the session list's Active filter hiding open idle sessions when Open is also checked in the filter menu
[VSCode] Fixed a new chat switching back to the previous chat when the session list refreshed
[VSCode] Fixed open tabs and the side bar keeping the old config folder until a window reload after CLAUDE_CONFIG_DIR changed in the environmentVariables setting
[VSCode] Fixed console windows flashing on Windows when the extension runs background commands such as git, ripgrep, and the sign-in status check
[VSCode] Fixed the prompt cache clock's hover text appearing only after a delay, and the auto-compact icon showing the browser's own tooltip beside its popup
[VSCode] Improved the Hooks dialog: a save refused because of the settings file itself now opens a popup with an "Open settings file" button and the reason behind "Copy error"
[VSCode] Changed the on state of toggle switches from Claude orange to the editor theme's button color
[Claude Code on the web] Fixed a cloud session sometimes taking about ten minutes to respond after its process exited while the session still looked live; sending a message now restarts it right away
[Claude Code on the web] Changed the Routines page on claude.ai/code to a new layout with Yours and Templates tabs and two-column routine cards that show run status, and removed its calendar view
[Claude Code on the web] Added a Custom network access option to the Cloud environments editor in admin settings, with the same allowed-domains list the environment dialog on claude.ai/code offers
[Claude Code on the web] Improved the Cloud environments admin page: it shows the default environment for Claude Tag and Claude Code, with a link to change it, and marks the recommended kind to create
[Claude Tag] Fixed Claude in a channel where it stays active losing its working context about once an hour when the conversation is mostly in threads; thread activity now keeps it from being reset
[Claude Tag] Fixed a thread that asked Claude to watch a pull request no longer hearing about CI failures, comments and reviews after Claude was restarted in that thread
[Claude Tag] Fixed deleting the first message of a thread Claude had already replied in not ending Claude's work there; it now stops, as it did when a message with no replies was deleted
[Claude Tag] Fixed Claude holding back a post because of an earlier instruction addressed to a different bot or assistant; only instructions addressed to Claude bind it, and it asks when unsure
[Claude Tag] Fixed the reply-mode card Claude posts on joining a busy channel saying it "sees a lot of automated posts" when the channel is only chatty or large; the card now names the real reason
[Claude Tag] Improved the Environment picker in Claude Tag admin settings: options are labeled Anthropic-hosted or self-hosted, with links to edit that environment or create one
[Code Review] Fixed a pull request in a repository reviewed once per PR sometimes getting no review when a commit arrived while its review was waiting to start; it now reviews the requested commit
[Code Review] Fixed Code Review occasionally posting the same findings two or three times when GitHub reported an error for a review it had in fact created
[Code Review] Fixed follow-up reviews re-posting a security finding a person had already resolved when a later push moved the lines it was anchored to
[Code Review] Fixed reopening a finished /ultrareview cloud session in the Claude app starting the whole review over again unprompted
Windows: Fixed PowerShell commands failing with "Exit code 1" and no output when the session's temp output path reaches 260 characters

●

v2.1.269 Sep 11, 2026

v2.1.269

What's changed

Added claude plugin eval: run a plugin's eval suite against Claude Code and get scored, reproducible results (JSON + HTML report); see claude plugin eval --help
Added /output-style [name] to list and switch output styles, including over Remote Control and in cloud and other headless sessions
Added a diff of the files a Bash command changed to the Bash tool result when the Bash tool handles file edits (setting bashEditDiffEnabled)
Added OTEL_METRICS_INCLUDE_REPOSITORY to tag OpenTelemetry metrics and events with vcs.* repository attributes; commit events get vcs.ref.head.* with OTEL_LOG_TOOL_DETAILS
Added CLAUDE_CODE_GATEWAY_MODEL_DISCOVERY_TIMEOUT_MS to extend the LLM gateway /v1/models discovery timeout (default 3s)
Added a spinner tip suggesting /focus for a view with just your prompt, a one-line work summary, and the response
Added CLAUDE_CODE_WORKFLOW_MAX_CONCURRENT_AGENTS (1–256) to raise the Workflow tool's per-run concurrent agent limit for inference-bound fan-outs
Fixed the prompt cache being partially invalidated on the turn after a response was cut off at the output-token limit and automatically resumed
Fixed a case where resuming a session after interrupting Claude mid-thought could change how earlier context was re-sent, hurting prompt-cache reuse
Fixed F1/F2/F4 not working in kitty-protocol terminals and Delete in st, Alt+arrows acting as Escape in rxvt-unicode, and Shift+punctuation typing the unshifted key in WezTerm (regression in 2.1.247)
Fixed remote and headless sessions reporting "waiting for your input" while background agents were still running (set CLAUDE_CODE_BG_TASKS_REPORT_RUNNING=0 to restore the old behavior)
Fixed the terminal's replies to capability queries (^[[?1;2c) appearing as stray text at startup in some terminals
Fixed rows at the top or bottom of the transcript going blank in fullscreen after resizing the terminal
Fixed a deny or ask permission rule starting with ! applying beyond the settings source that wrote it; such a rule now applies only within its own source, and a bare ! negation is ignored
Fixed the git status Claude is told after a compaction: it is now the current status, not the one from the start of the session
Fixed synced plugin MCP servers not connecting when a remote session resumes
Fixed resumed headless sessions losing a turn's replies when the model was switched or a request was retried mid-turn
Fixed terminal escape codes, line breaks and oversized text from a background task's on-disk record reaching the task list and task notifications when work is resumed
Fixed CMYK JPEG images failing to attach with "cannot decode"; they are now converted and resized like other JPEGs
Fixed the managed settings approval dialog not naming the collector for a gRPC telemetry endpoint set without a scheme
Fixed plugin headersHelper consent prompts showing a URL path that could be misread as a different host
Fixed plugin errors showing [redacted URL] in place of a relative Windows path with a folder name that starts with @
Fixed missing cursor in the permission-rule, auto-mode-rule, add-directory, session-rename and feedback-review text fields when the terminal's native cursor is enabled
Fixed repeated clicks on a /fork receipt, each under a second apart, never backgrounding the session right away while it waited for the current tool to finish
Fixed plugin LSP servers that reject shutdown params (e.g. rust-analyzer) being left running at session end; exit is now sent even if shutdown fails
Fixed the attribution reminder overriding a CLAUDE.md or memory rule against commit and pull request attribution; lines set by managed settings still apply
Fixed prompt suggestions being dropped for text in Japanese, Chinese, Thai and other languages written without spaces between words
Fixed synchronized output being assumed from the terminal's name in GNOME Terminal and Konsole versions that do not support it
Fixed permission_denials in --output-format stream-json results omitting Read, Edit and Write calls blocked by a path-scoped deny rule
Fixed sessions run through the SDK or the desktop app showing an unknown status in other sessions' agent list
Fixed /insights failing on Bedrock, Vertex, Foundry, and gateway deployments whose account can't reach the default Opus model by using the session model there instead
Fixed organization policy limits not loading for the session when another Claude Code process refreshed the login at the same moment
Fixed Claude Desktop sessions using Bedrock, Vertex, or a gateway not getting the contextual "what Claude needs" turn-end notification text
Fixed MCP servers reconnecting when an updated config only changed the order of the server URL's query parameters
Fixed the prompt box's top border splitting into extra lines when viewing a background agent whose name or description has line breaks or is wider than the terminal
Fixed sessions getting permanently stuck on "Prompt is too long" when auto-compaction had no complete earlier exchange to summarize (mostly Agent SDK sessions with very large prompts)
Fixed /goal runs silently stalling after API errors, network drops, or token limits: the goal now retries with backoff, or pauses and says why, including until a usage limit resets
Fixed prompt cache misses in cloud sessions by waiting briefly for server configuration before the first request
Fixed /btw answers that contained made-up tool calls and output: the side question is now told not to write them, and any that appear are flagged as not executed
Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN re-running a turn that had failed with an API error over 6 hours earlier, or longer ago than CLAUDE_CODE_RESUME_INTERRUPTED_TURN_MAX_AGE_MS when set
Fixed organization plugins enabled through managed settings not loading in headless sessions and on Claude Desktop (once Desktop bundles this CLI version); they load from the next session
Fixed plugin archives extracted for a session being readable by other local users, extracted files keeping world-writable bits from the archive, and stale files surviving re-extraction
Fixed Edit() deny rules and the write-path check not applying to the file a Bash tee command writes; a Bash(tee:*) allow rule no longer covers destinations outside the working directories
Fixed stray characters like 22c, or a terminal's color or version reply, being typed into the prompt at startup over slow connections (ssh, browser terminals)
Fixed the terminal's block cursor showing under the interface in rxvt-unicode after leaving or re-entering fullscreen
Fixed the cursor block staying visible after returning from an external editor in fullscreen mode on rxvt-unicode
Fixed the interface being drawn twice after returning from an external editor (Ctrl+G) outside fullscreen mode
Fixed the interface being drawn twice in Konsole after returning from an external editor
Windows: Fixed PowerShell tool commands sent to the background stopping when Claude Code exits
Improved the /diff panel to open fully rendered in one step instead of showing a loading state first
Improved prompt suggestion filtering for Japanese, Chinese and Korean text: mixed-script and single-word suggestions are kept, and meta or evaluative text is dropped as it is for English
Improved the Skill tool's "Unknown skill" error to name the plugin skill's full name when a bare name matches exactly one plugin skill
Improved keyboard support over SSH and in unrecognized terminals: terminals that answer the kitty keyboard query (such as foot and Alacritty 0.16+) now get Shift+Enter and Ctrl+Shift shortcuts
Improved responsiveness in long sessions: transcript updates no longer re-process the whole conversation to build the collapsed tool-use summaries
Improved first-party sessions with telemetry disabled: an alwaysLoad MCP server that finishes connecting mid-conversation is usable on the next turn without a tool-search round trip
Changed /ultrareview --post to post the PR comment directly when the findings arrive and print the comment link, instead of starting a second cloud session to post it
Changed artifact database reads that save into the session scratchpad so they no longer stop for working-folder approval
Changed skills synced from claude.ai in cloud sessions to be named anthropic-skills:<name>, matching Claude Desktop; the bare name still works when nothing else uses it
[VSCode] Added an agent map: an "N agents" footer pill opens a map of the session's sub-agents with per-agent cards, Stop agent, and read-only transcripts
[VSCode] Added a Hooks dialog to the command menu for viewing hooks and adding, editing, or removing them in user, project, and local settings; managed, plugin, and session hooks stay read-only
[VSCode] Added live progress rows for running subagents under the tool-call groups in Focus view
[VSCode] Added a Permission rules dialog that lists permission rules and adds or removes them in user, project, and local settings; startup-option, session-only, and managed rules stay read-only
[VSCode] Added a Cancel button to the Switch account screen that returns to your session as the current account
[VSCode] Fixed Focus view showing a turn started by a delivered plain-text prompt, such as a scheduled task's, as part of the previous turn
[VSCode] Fixed the footer's prompt cache clock hiding its minutes when the panel is narrow
[VSCode] Fixed the session list keeping sessions from the default folder when CLAUDE_CONFIG_DIR is set in a settings file or the environmentVariables setting
[VSCode] Fixed a plan preview that finished loading late sometimes hiding its comment box or showing an older plan
[VSCode] Fixed a plan preview accepting comments that went nowhere after its Claude tab closed
[VSCode] Fixed the prompt cache clock and reopen notice for a session compacted after its last reply and then closed, which now reads as cold when reopened
[VSCode] Fixed a session renamed in the extension while Remote Control is on keeping its old name on claude.ai/code
[VSCode] Fixed the "Enable Remote Control for all sessions" toggle keeping its last position after the setting was reset to default from a terminal
[VSCode] Fixed restored Claude tabs not counting as open in the session list after a window reload until clicked, and their row opening a second tab
[VSCode] Fixed Switch account making a tab forget its dismissed usage-limit warnings when you sign back in as the same account
[VSCode] Fixed a session rename being replaced by the generated name after a window reload when the session was renamed during a long turn
[VSCode] Fixed the sidebar usage meter keeping a stale per-model weekly limit row after the account loses that limit
[VSCode] Fixed a rare case where an @-mention sent with the keyboard shortcut while a new chat view was still starting could be inserted into the input long after the keystroke
[VSCode] Fixed the session list jumping down when the Account & usage header appeared a moment after opening the Claude side bar
[VSCode] Improved documents and messages written for someone other than the user: Claude now writes them for that audience and names it at the top of its reply
[VSCode] Improved screen reader and keyboard accessibility in the slash-command menu, @-mention menu, output-style picker, Send/Stop button, permission and question cards, and onboarding checklist
[VSCode] Changed the current-file chip in the message box: an X now removes it, replacing the Hide toggle
[VSCode] Removed the Claude Code items from a session tab's right-click menu and the editor title bar's "..." menu; they could not act on the tab the menu was opened on
[Claude Code on the web] Added taking back a queued message in a cloud session before Claude reads it: remove it from the queue, or press Esc or Up, and the text returns to the message box
[Claude Code on the web] Fixed /model default in a cloud session leaving every later message failing in organizations that restrict which models Claude Code can use
[Claude Code on the web] Fixed one-off scheduled routines occasionally running a second time after a transient server error
[Claude Code on the web] Fixed routine runs that use subagents sometimes being treated as finished too early, which could skip the retry after a real failure or start a duplicate run
[Claude Code on the web] Fixed file links in cloud session transcripts opening a GitHub 404 when Claude was working from a subfolder of the repository
[Claude Code on the web] Changed the Cloud environments admin page to list every environment instead of capping each table at five rows behind a Show more control that could be unreachable
[Claude Code on the web] Changed claude.ai/code for Free-plan users to open the plans page with a path to upgrade, instead of a "Disabled by org admin" page with no way forward
[Claude Tag] Added a confirmation dialog before Connect all or Disconnect on a GitHub installation in admin settings, to guard against accidental organization-wide changes
[Claude Tag] Fixed threads occasionally going silent after a failed turn because the failure notice was dropped when Slack briefly rate-limited it; the notice is now retried
[Claude Tag] Fixed Claude accepting a switch to a model your organization hasn't enabled and then quietly answering with a fallback model; it now declines and says an admin can enable it
[Claude Tag] Fixed a table posting as raw pipe text when Claude attached files to the same message; the table now posts as a normal reply and the files follow with a plain caption
[Claude Tag] Fixed @Claude !restart at the top level of a channel where Claude isn't active starting an unrelated conversation; it now privately says there is nothing to restart
[Claude Tag] Fixed plugin rows in Slack access settings showing an unlabeled raw ID with no way to turn the plugin off; they now show its name and link to the bundle that manages it
[Claude Tag] Fixed the shared-session banner and Share dialog on sessions started from Slack claiming the whole organization could open the link; they now name the Slack channel's audience
[Claude Tag] Improved load time of the admin settings page and its Slack channel picker, most noticeably for organizations with many channels or several connected workspaces
[Claude Tag] Improved scheduled routines in Slack channels: a routine run can now reply in an existing thread instead of always posting a new top-level channel message
[Claude Tag] Improved the timestamp on Claude's live progress checklists to show each reader's local time and how long ago it was updated, instead of a fixed UTC time

v2.1.268 Sep 10, 2026 Breaking

v2.1.268

What's changed

Added to the Claude apps gateway: with pricing: set in gateway.yaml, signed-in Claude Code clients receive the same rates through managed settings, so /cost and telemetry match the spend meter
Added a startup warning for gateways when access_control.allow_cidrs is empty, and a one-time warning the first time a request arrives from a public address
Added the gatewayInternalNetworks managed setting, letting administrators allow /login to a Claude apps gateway on their organization's own public IPv4 block
Added claude self-hosted-runner --remove-session-state (default off): delete each session's per-session directories under <base-dir>/_sessions/ when the session ends
Added configDirectory to the output of claude auth status --json
Added --json to claude plugin install, uninstall, update, enable and disable, and errorDetails/noteDetails to each row of claude plugin list --json
Added browser-tab icons for published artifacts, chosen by Claude to match each page
Fixed every turn failing with HTTP 400 on third-party Anthropic-compatible endpoints (ANTHROPIC_BASE_URL) since 2.1.265: a regex in the Artifact tool's input schema that those endpoints reject
Fixed WebFetch hanging indefinitely on a server that keeps the response open without finishing; a fetch now fails after 300 seconds. Set CLAUDE_CODE_WEBFETCH_DEADLINE_MS to override the deadline (0 turns it off)
Fixed a respawned in-process teammate picking up tools or a system prompt from a same-named agent file in a folder you have not trusted
Fixed sustained high CPU usage: a busy loop in long-running idle sessions no longer pins a CPU core, and rapid terminal focus reports during a session recap no longer keep the CPU high
Fixed Claude sometimes replying "your message came through empty" after an MCP tool call
Fixed deny and ask permission rules on symlinked directories (/etc, /tmp, /var on macOS; /bin on Linux) not applying when a path was given by its real location, and Bash commands ignoring deny rules written on a symlinked path spelling
Fixed a case where a Read or Edit deny rule did not apply when an env -C, eval or similar command the permission checker cannot analyze was on the same line
Fixed plugin and marketplace errors showing a token or password from a git source URL
Fixed /mcp and /plugin server details, claude mcp list/get, and MCP login errors showing secrets resolved from ${VAR} placeholders in MCP configs
Fixed prompt caching and extended thinking breaking mid-session for SDK sessions using excludeDynamicSections: the first message is no longer re-rendered each request
Fixed entitled users being told a model is restricted after restart or in the Desktop Code tab when a cached model-access denial was stale
Fixed a running session silently switching to the organization's default model when another Claude Code process refreshed a stale model-access entry
Fixed long-context 429s on Fable models showing the usage-credits consent prompt instead of the 1M-context message on Pro and Team plans
Fixed workload identity federation via a profile (as claude-code-action configures it): processes sharing the profile could fail mid-run with 401 … jti reused
Fixed MCP server OAuth sign-in failing with "No available ports for OAuth redirect" when the local callback port range can't be bound
Fixed the conversation summary produced by /compact and auto-compact mangling text that contained $ sequences
Fixed resuming a conversation that ended with /compact: its restored-file notes now load in the same order on every resume
Fixed SDK prompt suggestions, side questions and /rename sending the conversation from before a compaction
Fixed @ file and / command suggestions not appearing after recalling a previous prompt with the up arrow and editing it
Fixed claude agents: pressing ← again at a natural pace to go back to the agent list no longer gets ignored until you pause for over a second
Fixed claude agents session delete getting stuck when a worktree can't be removed: the message names the cause and next step, and for a git worktree ctrl+x again deletes the directory anyway
Fixed background agent and workflow rows in the agents panel expanding to many lines when their text contained line breaks
Fixed Claude in Slack sessions losing their Slack tools when org managed settings set an MCP allowlist
Fixed Claude in Chrome asking to allow the host "https" when a navigation URL had a scheme but a host that could not be parsed
Fixed the spinner wrapping onto several lines when the current task's label is long; the label and the "Next:" task line now stay within one terminal row
Fixed the /bug and /feedback description field showing no cursor when the terminal's native cursor is enabled
Fixed Remote Control sessions served by claude remote-control showing a generated name instead of their session title in ListAgents
Fixed claude plugin validate rejecting plugin paths whose directory name begins with two dots, which the plugin loader accepts
Fixed plugins silently skipping a default monitors file or root SKILL.md that could not be checked
Fixed WebFetch's error for localhost and other dotless hostnames to explain why the URL is refused and suggest curl
Fixed PermissionRequest hooks not firing in --print mode
Fixed policy-helper warnings not printing on headless (-p) runs
Fixed /resume listing a /fork background session under its parent's name instead of its own ⑂ fork name
Fixed /remote-control and other claude.ai-gated commands to suggest /login when signed out instead of showing a Claude for Enterprise migration message
Fixed CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS not extending SessionEnd hooks that have no per-hook timeout (they were still cancelled after 1.5 seconds)
Fixed /autofix-pr and other cloud-session commands saying to retry or install the Claude GitHub App when no GitHub account is connected; they now point to /web-setup or the web connect page
Fixed cloud-session commands such as /teleport and /remote-env to explain when an organization policy turns them off, instead of answering "Unknown command"
Fixed Bash sandbox instructions over-stating confinement: no unenforced path lists when filesystem isolation is off, and strict mode no longer claims commands can never run unsandboxed
Improved fullscreen mode: adding or removing a prompt line (Shift+Enter) now repaints as fast as typing a character instead of re-rendering the visible transcript
Improved --continue / --resume: the conversation appears immediately instead of waiting for SessionStart hooks, and the first message no longer re-reads the whole transcript
Improved responsiveness during tool-heavy turns by no longer redrawing the transcript for a hidden per-tool-batch reminder
Improved startup time in projects with .claude/workflows/ scripts: listing them no longer parses each script
Improved auto mode denials: the message Claude receives now names the rule that blocked the action and asks Claude to try a safer method and finish unrelated work before stopping to ask you
Improved Claude in Chrome: long page reads now stay inline instead of being saved to a file and read back
Improved the MEMORY.md truncation warning to say how many lines were cut and where the cut starts
Improved the terminal permission prompt for artifacts: it now leads with the ask's question
Improved the prompt footer: an editor or /diff selection now shows inside the prompt input, and fullscreen mode shows Remote Control status in the header instead of the footer
Improved the "Usage credits required for 1M context" message to say that usage credits turned on mid-session take effect after restarting Claude Code
Improved /plugin: installing, enabling or disabling a plugin now takes effect when you close the menu; /reload-plugins is no longer needed afterwards
Changed the system prompt on Bedrock, Vertex and Foundry to deliver environment, model and settings details as attachments, matching first-party sessions
Changed Bedrock, Vertex and Foundry sessions to keep the tool list byte-stable across a conversation (late-connecting tools load deferred instead of rewriting it), matching first-party sessions
Changed the task-tracking tools (TaskCreate/Get/Update/List, TodoWrite) to be offered only on Claude 3.x, Opus 4.0–4.7, Sonnet 4.0–4.6, Haiku 4.5; set CLAUDE_CODE_ENABLE_TODO_TOOLS=1 elsewhere
Changed the artifact data-edit permission prompt in the terminal to a card that shows the document count and who can open the artifact
Changed local Cowork sessions set to skip all approvals: the Artifact tool now refuses a local file outside the session's folders, or behind a symlink, instead of reading it without asking
Changed plain WebFetch deny and ask rules to no longer apply to Artifact tool reads and updates; use an Artifact rule (or WebFetch(domain:claude.ai)) to block or gate them
Changed the "N MCP servers need authentication" startup notice to announce each server once instead of at every launch
[VSCode] Fixed the session list, settings toggles, and chat tabs when CLAUDE_CONFIG_DIR is set in a settings file or the environmentVariables setting
[VSCode] Fixed the model pill, model picker and command menu going blank in open tabs for a few seconds after a login, logout or account switch
[VSCode] Fixed Auto disappearing from the mode picker in new-tab or just-reloaded conversations when a project or local setting overrides the model named in ~/.claude/settings.json
[VSCode] Fixed session names reverting to the last prompt after a window reload when a SessionStart hook is configured
[VSCode] Fixed the footer's model pill and Remote Control pill waiting for the new tab's Claude process to start when another tab in the window is already up
[VSCode] Fixed a second Claude process running through its full startup when a session tab's launch arrived more than half a second after its config read
[VSCode] Fixed resuming a session from the session list ignoring claudeCode.preferredLocation: "sidebar" (it always opened a panel), and programmatic opens resetting that setting to "panel"
[VSCode] Fixed Windows issues: the WSL install prompt no longer appears on machines without WSL installed, and IDE diagnostics are now returned correctly for Windows files when WSL is installed
[VSCode] Fixed the custom style builder saving a User level style in a folder the CLI does not read when CLAUDE_CONFIG_DIR is set through settings
[VSCode] Added Left and Right arrow keys to change where an always-allow permission rule is saved, for keyboard and screen reader users
[VSCode] Added a "Claude Code: Focus last message" command that moves keyboard focus to the newest message in the conversation, for keyboard and screen reader users
[VSCode] Changed the Manage plugins dialog to apply installs, enables, disables and uninstalls to open sessions without a restart
[VSCode] Changed some artifact permission prompts to omit the "don't ask again" choice, matching the terminal
[Claude Code on the web] Fixed cloud sessions running longer than about six hours silently losing files saved to persisted session folders; saves now persist for up to a day
[Claude Code on the web] Fixed "Invalid effort level" errors when a routine resumes a session, or a session starts with no set effort, in orgs where an admin caps a model's effort
[Claude Code on the web] Improved routine creation from a conversation: when the new routine has no connectors, Claude now says so and how to add them instead of only confirming it
[Claude Tag] Fixed the admin settings page hanging on a loading skeleton or going blank after a transient load failure; a section that fails to load now shows a Retry button
[Claude Tag] Added a link from a Slack channel's configure page back to the organization's Claude in Slack admin settings
[Claude Tag] Fixed a Slack Enterprise Grid channel losing its Claude settings (repository, environment, access) after a Slack admin moved it to another workspace
[Claude Tag] Improved how Claude explains a blocked action: it now says whether a permission check, its own decision to confirm first, or missing access stopped it
[Claude Tag] Improved reply speed: Claude now runs several read-only lookups (searching Slack, reading a thread, finding people) at once instead of one after another
[Claude Tag] Improved formatting of comparisons: sentence-length comparisons now come as lists instead of wide tables that scroll sideways, and long table cells wrap
[Claude Tag] Fixed @Claude !restart in a thread with its own session sometimes also posting a contradictory "this thread is handled by the channel session" notice
[Claude Tag] Improved the message shown when your Claude account is in a different organization than the Slack workspace: it now explains how to connect the workspace to your org
[Claude Tag] Fixed Markdown links whose URL is wrapped in angle brackets showing as literal bracket text in Slack instead of a clickable link
[Claude Tag] Fixed a workspace guest's top-level @mention in a channel where guests may use Claude sometimes getting a "your Slack account isn't connected" reply instead of an answer
[Claude Tag] Fixed a channel's long-running session being replaced with a fresh one mid-conversation; the scheduled refresh now waits until the channel and its threads are quiet
[Claude Tag] Fixed channel-settings cards clicked more than once telling the proposing session the change was refused after it had already applied; the outcome is now sent once
[Claude Tag] Changed memory in public channels: each channel now keeps its own notes, and Claude no longer recalls notes it saved in other public channels; workspace notes stay shared
[Code Review] Added a note under the still-open findings list in follow-up reviews: resolving a finding's thread, not just replying to it, stops later reviews from counting it as open
[Code Review] Fixed reviews sometimes ending as incomplete when one of the agents verifying a finding failed midway; the review now replaces that agent and reaches a verdict
[Code Review] Fixed a push-triggered review that was queued behind a running review still posting after the pull request had been converted to draft
[Code Review] Fixed reviews ignoring a directory's CLAUDE.md conventions when the PR edited a root file (e.g. README.md) that only shares a name with a file that CLAUDE.md lists

v2.1.267 Sep 9, 2026

v2.1.267

What's changed

Added maxEffortLevel setting (top-level or per model under modelSettings): caps the effort level on every provider, including Bedrock, Vertex and Foundry; users can still pick a lower level
Added --system-prompt-snapshot off to render the system prompt fresh on every request instead of reusing the conversation's recorded prompt (for iterating on prompt text)
Fixed Cowork scheduled tasks in the cloud failing at startup for organizations whose managed settings require sandboxing
Fixed /context and other local command output rendering blank on mobile clients
Fixed shift+enter and option+backspace not working after reconnecting to a tmux or ssh session inside an agent view
Fixed the dim last-prompt header not appearing at the top of the conversation when scrolling up in fullscreen mode
Fixed Workflow agent() calls with large output schemas being refused in auto mode instead of being checked by the safety classifier
Fixed a case where a marketplace entry path containing a backslash could bypass the containment check for fetched marketplaces on macOS and Linux
Fixed expired AWS or Google Cloud credentials under a host app such as Claude Desktop retrying ten times with a generic "request failed" before the re-authenticate error appeared
Fixed resuming a session after /compact or another slash command ran via -p --resume: a spurious "Continue from where you left off." turn is no longer inserted
Fixed resuming a large session (transcript over 5 MB): parallel tool calls and their hook output are no longer dropped from the reloaded conversation
Fixed managed allowedHttpHookUrls, httpHookAllowedEnvVars and allowedChannelPlugins to admit nothing, not everything, when unreadable
Fixed /login on machines whose managed settings require Claude apps gateway sign-in: Esc now closes the dialog instead of doing nothing
Fixed artifact publishes cut off by a dropped connection mid-upload: they now retry once when Claude Code can tell the upload never completed, instead of reporting an unknown outcome
Fixed effort: frontmatter on custom commands, skills, and subagents being ignored on models whose default effort is still pinned (Opus 4.7, Opus 4.8, Fable 5)
Fixed artifact publish failing with an unhelpful error when the page file isn't valid UTF-8 or contains a replacement character (U+FFFD); the error now names the line and column to fix
Fixed claude agents @ directory menu not listing repositories created after the session started
Fixed Remote Control clients that join a Claude Desktop or VS Code session showing a stale permission mode until it was changed again
Fixed claude remote-control exiting and dropping every attached session when its server credential expires (about 30 days after start); the host now re-registers and keeps going
Fixed the usage-limit warning flickering on and off during a session when requests for different models or modes report different limit windows
Fixed earlier reasoning being dropped when an MCP server re-sends, or a built-in tool re-renders, a tool the model already loaded
Fixed a tool that disappears mid-conversation, from a disconnected MCP server or an upgrade, rewriting the tool list and discarding earlier thinking
Fixed a background worker forked from a conversation adding EnterWorktree to the conversation's tool block mid-session, which broke prompt-cache reuse
Fixed mid-session MCP and plugin tools being added to the tool list in sessions without ToolSearch, which broke prompt-cache reuse; supported models now receive them as deferred definitions
Fixed switching models with /model re-sending every tool definition (a prompt-cache miss); commit and PR attribution text now arrives as a conversation note that updates on model changes
Fixed resumed sessions rewriting the inline tool set when an MCP connector reconnects at a different moment than before
Fixed resumed sessions re-rendering tool descriptions instead of replaying the recorded ones when the first turn ran a tool
Fixed prompt-cache misses and dropped extended thinking when a claude.ai connector's tools change between a session and its resume
Fixed resumed sessions rewriting earlier MCP tool announcements (and dropping extended thinking) before their connectors reconnect
Fixed a prompt-cache break when a print-mode (-p) conversation is resumed interactively: the system prompt prefix no longer changes
Improved the /diff panel: it no longer flashes "0 files changed" and a spinner before settling, and its empty state is centered in the panel
Improved the Bash tool's description guidance so Claude describes what a command does in plain words instead of echoing the command
Improved sandbox guidance so Claude suggests /copy when clipboard commands such as pbcopy fail inside the sandbox
Improved --resume first-render time for sessions with many Bash tool calls
Improved prompt input responsiveness: keystrokes no longer occasionally wait a frame behind spinner or streaming repaints
Improved prompt-cache stability: subagents and sessions started with --system-prompt or --append-system-prompt now record the system prompt and tool definitions once instead of re-rendering them
Improved Artifact tool publish errors: when a publish is refused, the message now says why and what to do about it
Self-hosted runner: Changed --use-anthropic-git-proxy to be reported to the server at registration and to print a warning for each session that still clones through the legacy git proxy
Gateway: Changed forward_user_identity upstreams to return a 429 as-is to a developer whose email was forwarded, instead of failing over to the next upstream, so the proxy's per-user limits hold
[VSCode] Fixed the extension host hanging at 100% CPU when forking, editing an earlier message, or rewinding in a conversation whose saved transcript contains a cyclic parent link
[VSCode] Fixed pasting a screenshot on WSL2/WSLg inserting raw image bytes into the chat input; the image is now attached when the clipboard provides it, otherwise the paste is ignored
[VSCode] Fixed chat diff blocks always rendering with a dark editor theme; they now follow the active VS Code color theme, including high contrast
[VSCode] Fixed mixed right-to-left and English text rendering in the wrong order while typing in the message input
[VSCode] Fixed accepting an edit in the diff view on a file with Windows (CRLF) line endings failing with "String not found in file"
[VSCode] Fixed @-mentions dropping files whose paths contain spaces
[VSCode] Fixed the sessions list view failing to load in windows connected over Remote-SSH when the workspace folder exists only on the remote host
[VSCode] Fixed runaway ripgrep processes when viewing files in large or symlink-heavy workspaces
[Claude Code on the web] Fixed GitHub Enterprise Server sessions showing your GitHub account as disconnected once its token expired; PR and issue operations now refresh it automatically
[Claude Code on the web] Fixed gh and GitHub API calls failing in organizations without the Claude GitHub App; they now use your connected GitHub account and say so when none is connected
[Claude Tag] Added a "Use a custom connector" link to the preset connection forms in Claude Tag admin settings, so you can switch to a custom connection without starting over
[Claude Tag] Fixed Claude replying "The API rejected the request as invalid" when the organization has run out of usage credits; the reply now says so and explains how to add more
[Claude Tag] Fixed thread requests to edit or delete a message Claude posted at the channel's top level being answered with a correction instead of reaching the session that posted it
[Claude Tag] Fixed Connect on Tool access requests under Admin settings > Review requests failing with "Authorization failed" or showing the requested access bundle as deleted

●

v2.1.266 Sep 8, 2026

v2.1.266

What's changed

Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented CLAUDE_CODE_USE_GATEWAY environment variable, previously ignored unless ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, apiKeyHelper, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed

●

v2.1.265 Sep 8, 2026

v2.1.265

What's changed

Added user.email and user.groups to the telemetry Claude Desktop and Cowork send through a Claude apps gateway, matching terminal sessions
Added support for pointing --plugin-dir at a folder of plugins: each child folder with a manifest loads, and children added or removed while running are picked up
Added a 1 GB cap on tool results saved to disk; the in-conversation preview says when a saved file was truncated
Fixed resuming a foreground-spawned subagent changing its tool list and system prompt prefix, which broke prompt-cache reuse for that agent
Fixed agent teammates and resumed subagents moving SubagentStart hook context and preloaded skills out of the prompt prefix on later turns, which broke prompt-cache reuse
Fixed resume after the previous process died while a tool was running: the last prompt is no longer rewritten, and the interrupted tool call is kept and marked interrupted
Fixed /model opusplan[1m] being rejected with "Model not found"
Fixed syntax-highlighted code in permission prompts and messages sometimes omitting a character after a Ruby ?, Erlang $, or Perl $ sigil
Fixed the fullscreen transcript jumping by one row whenever the slash-command or @-file suggestion list opened or closed
Fixed a plugin path containing a backslash bypassing the symlink containment check on macOS and Linux
Fixed plugin directories whose names begin with two dots being wrongly refused as outside the plugin root
Fixed VS Code and SDK sessions occasionally requiring re-login when a session was closed while refreshing its token
Fixed Remote Control sessions sending the end-of-turn signal before the reply's last message, which could show a reply as finished in the Claude app before its last part arrived
Fixed background (--bg) sessions occasionally being retired mid-turn when a message arrived just before the idle timeout
Fixed Claude Code's own git status and diff probes running clean filters configured by a nested repository inside the working tree
Fixed the advisor tool and its instructions being re-decided per request from the request's model; the decision is now made once and announced in the conversation when it changes
Fixed artifact publish accepting connector tool names the connector doesn't expose; the publish is now refused when none of the declared tools exist, and warned when only some don't
Fixed /add-dir <subdirectory> refusing to load a subdirectory's agents when managed settings lock only skills to plugins, and promising agents when only agents are locked
Fixed two-key keyboard shortcuts cancelling silently when the second key arrived more than a second later, as happens inside tmux; they now wait 3 seconds and show a notice when they time out
Fixed forked skills (context: fork) not streaming their kickoff prompt and, with --forward-subagent-text, their text turns as progress events in stream-json
Fixed a plugin's default component folder that the OS cannot check, such as a symlink loop, being silently skipped; it is now reported in /plugin with the error code
Fixed the Claude apps gateway's OTLP telemetry relay pausing all forwarding to a collector for 30 seconds after it rejected a few payloads as malformed or too large
Fixed /plugin Discover/Browse and claude plugin list --json --available showing no description or display name for marketplace plugins whose metadata lives only in their plugin.json
Fixed /login showing "no gateway URL is configured" when re-run in a session that signed in to a Claude apps gateway set by managed settings
Fixed /model claiming a model was "saved as your default" when the settings file couldn't be written; it now says the save failed and why
Fixed /clear from Remote Control waiting on SessionStart hooks and on open terminal dialogs before completing
Fixed the /config dialog changing height when switching between its tabs
Fixed resuming a workflow run after its container restarted; a resume whose run journal is missing now fails with a clear error instead of rerunning every agent
Fixed the claude-api skill's error-code reference: model access failures return 404 and unavailable beta headers return 400, not 403
Fixed non-interactive sessions (-p with stream-json input, Agent SDK, cloud sessions) resetting the shell working directory at each new user message; a cd now persists across turns
Fixed MCP servers configured as http that only speak the legacy HTTP+SSE transport never connecting; Claude Code now falls back to SSE as the MCP spec describes
Fixed some claude.ai connectors in cloud sessions showing as needing authentication even though they are connected in claude.ai (servers that answer an unsupported request with HTTP 401)
Fixed remote sessions keeping their sandbox container alive while a connector approval or sign-in link waits for you
Fixed resumed sessions showing long model-facing recovery instructions in "background task didn't finish" notices instead of a short status line
Windows: Fixed Read, Write and Edit refusing every file ("symlink resolution changed after permission was checked") when running inside an AppContainer or restricted-token sandbox
Improved --worktree startup on large repositories: the new worktree is now checked out in parallel (git 2.32+)
Improved /workflows agent detail: tool calls are marked running, failed or done, the subagent's task list is shown when it has one, and Enter unfolds the listed calls with their inputs and results
Improved slash commands typed mid-prompt: matches now show in a list (Tab opens it outside fullscreen) instead of a single suggestion, and a plugin skill is now found by its bare name
Improved remote MCP servers that need sign-in: Claude Code no longer registers an OAuth client with them until you actually authenticate
Improved the time to resume long sessions that read many files
Improved the error shown when an image over the size limits cannot be decoded: it now names the cause and how to fix it instead of only citing the limit
Improved the Artifact tool's read of an artifact someone else wrote: the summary now treats the page as untrusted content and flags embedded instructions rather than relaying them
Updated the .claude folder permission option to say what it actually allows: editing files in the project's .claude folder (or ~/.claude) for the session
Changed machines with forceLoginGatewayUrl in managed settings to be Claude apps gateway sessions from startup, like forceLoginMethod: "gateway"; a leftover claude.ai login or API key is not used
Changed image processing to use the runtime's built-in image support; the CLI no longer extracts a native image module to the temp directory
Changed plugin display metadata to prefer the marketplace entry over plugin.json on the Installed tab and claude plugin details, filling gaps from plugin.json
Changed Claude apps gateway sessions to export OpenTelemetry directly to a collector the gateway's managed settings name in OTEL_EXPORTER_OTLP_ENDPOINT, instead of through the gateway's relay; sessions without a named collector still use the relay
[VSCode] Added automatic archiving of sessions inactive for a set period (new "Archive inactive sessions" setting, default 14 days)
[VSCode] Fixed the sidebar chat coming back blank after Reload Window or a restart when the conversation had been open for more than 10 minutes
[VSCode] Fixed the timeline dot sitting below the text on the "Remote Control is active" message

v2.1.263

What's changed

Bug fixes and reliability improvements

●

v2.1.261 Sep 4, 2026

v2.1.261

What's changed

Added an "Organization policy" line to /status and claude doctor that says why your organization's policy could not be loaded, such as a proxy not passing the endpoint through
Added bashOutputMaxChars and taskOutputMaxChars settings to raise how much command and background-task output Claude receives inline before it is saved to a file, up to 128K characters
Added --append-subagent-system-prompt-file to read the subagent system prompt from a file, for prompts too large to pass on the command line
Added /skill-doctor to show which loaded skills go unused and what they cost in context, so you can prune them
Fixed typed or pasted characters occasionally landing out of order or being dropped during fast input or key repeat
Fixed /add-dir <subdirectory> printing a false "couldn't be resolved" error when the working directory is on a /net automount
Fixed the Bedrock setup wizard hanging when AWS or an AWS credential helper never responds (it now times out with a clear error), and its model checks failing behind a TLS-inspecting proxy
Fixed cloud sessions discarding a plugin synced from claude.ai when managed settings force-enable it in enabledPlugins, then falling back to a marketplace clone that could fail
Fixed being unable to delete the character immediately before an inline [Image #N] chip in the prompt input
Fixed resuming a session losing hook output and other context around parallel tool calls, which changed the resumed request
Fixed Remote Control showing a stale permission mode when a phone, browser, or claude.ai app attaches to a terminal session or after the mode changes in the terminal
Fixed Remote Control sessions showing as still working (stuck spinner and Stop button) after stopping a turn from a connected phone or browser, or after a local slash command like /clear
Fixed SDK and cloud sessions ignoring a Stop or interrupt sent just after the first prompt, before the turn had started; the turn now stops instead of running to completion
Fixed Remote Control uploading a session pulled with /teleport into the connected session, which appeared appended to the original on phone and web
Fixed Remote Control's inbound event stream failing behind TLS-inspecting corporate proxies on native Windows
Fixed Remote Control sessions showing the default effort level on claude.ai when the effort comes from settings
Fixed gcpAuthRefresh opening a browser at startup when the Google credential check was slow, even though the credential was still valid
Fixed claude.ai connectors staying absent for the whole session when the startup connector fetch timed out — the CLI now retries in the background
Fixed sustained high CPU usage when a background agent could not be resumed and its wake-up was retried in a tight loop
Fixed feature flags gated to a newer version occasionally applying to an older Claude Code version running on the same machine
Fixed /usage and the VS Code usage panel dropping a model-specific weekly limit row when the usage endpoint is rate limited or when opened right after startup
Fixed claude -p --resume <file> adopting a malformed session ID recorded in the transcript; it now resumes under a fresh session ID instead
Fixed the terminal progress indicator (iTerm2, Ghostty, ConEmu) showing the session as finished while a background workflow or agent was still running
Fixed a rare layout glitch where a box could render with the wrong height after its container switched between row and column direction
Fixed Claude apps gateway client IP when a trusted proxy appends a port to X-Forwarded-For; with an access list set, an unreadable entry now gets 403
Fixed Claude apps gateway telling Claude Desktop to export OpenTelemetry as JSON even when the terminal CLI uses protobuf, so protobuf-only collectors rejected Desktop's data
Fixed Desktop and web showing a session as busy while it only watches an artifact for updates
Fixed Claude in Chrome file_upload failing with "paths: expected array, received undefined" in local Cowork sessions run from the Claude Desktop app
Fixed SendMessage to an offline Remote Control session on another machine reading as delivered; the result now says delivery is queued until that machine reconnects
Fixed plugin install hints from CLIs run in background Bash commands: they are now detected, and the raw <claude-code-hint> tag no longer leaks into the conversation
Fixed in-process agent-team teammates re-sending their first-turn tool and skill announcements on the second turn, which changed the request prefix and missed the prompt cache
Improved the /model picker and the VS Code model pill to show a model's name instead of its raw Bedrock, Vertex AI, or LLM gateway ID when Claude Code recognizes it
Improved startup on Google Vertex AI when GOOGLE_APPLICATION_CREDENTIALS is set: API client creation no longer re-runs Google Cloud project discovery or spawns extra gcloud processes
Improved streaming performance: already-rendered blocks are no longer re-checked by layout on each update
Improved the dangerous-rm safety prompt to also catch rm -rf on positional parameters and inside double-quoted sh -c scripts
Improved handling when the API sends no response headers: the retry now waits up to API_TIMEOUT_MS (10 minutes by default) instead of another 3 minutes, and the messages say what to change
Changed a Claude apps gateway 403 on the managed settings load (at startup or after /login) to say Claude Code may not be enabled for the organization, instead of advising a new sign-in
Changed machines whose managed settings pin forceLoginMethod: "gateway" to ignore a leftover API key or claude.ai login and ask for /login; Bedrock, Vertex AI, and Foundry sessions are unaffected
Changed auto mode to treat a link that packs content into a public diagram renderer's URL as an upload to that site: no longer auto-approved unless you asked for it
Changed the prompt's word-editing keys to match Bash: Ctrl+W deletes back to whitespace, Alt+F and Alt+D stop at word end, punctuation separates words; keybindingFlavor no longer has any effect
Changed /context token counting to use a local estimate when the token-counting API is unavailable, instead of extra small-model requests
[VSCode] Added a "Build a custom style" walkthrough to the Output styles menu that writes a custom output style file and lists it right away
[VSCode] Added an Add server form and a Remove action to the MCP servers dialog, so MCP servers can be added and removed without leaving the IDE
[VSCode] Added a hollow ring in the session list for sessions open in a terminal, another VS Code window, or Claude Desktop, so they no longer look closed
[VSCode] Added a fold button to permission and question prompts so the conversation behind them can be read without dismissing them; the space beside the prompt now scrolls the conversation
[VSCode] Added "Archive session" to the session list's right-click menu and gave Unarchive its own icon
[VSCode] Fixed a session teleported from Claude Code on the web treating a question that was cut off when the cloud session shut down as declined
[VSCode] Fixed the session tab's Rename box opening empty for a tab restored with the window; it now starts with the current name
[VSCode] Fixed collapsed sections in the session list panel briefly showing expanded each time the panel loaded
[VSCode] Fixed Focus view showing a tool call as still running after Claude had moved on, such as while a question waited for your answer
[VSCode] Fixed the session list's active-row highlight going stale when an unfocused Claude tab's session ID is corrected
[VSCode] Fixed Cmd/Ctrl+Shift+T reopen and deep-link opens placing the Claude tab outside the Claude editor group when a Claude tab has focus
[VSCode] Fixed the session tab's "Add to group" putting a session opened from Claude Code on the Web in two groups; it now moves the entry the session list shows
[VSCode] Fixed the model picker showing models an organization has since disabled until the window was reloaded twice
[VSCode] Fixed a tab opened from the session list jumping back to that session, and a tab opened from a Web session restarting its teleport or staying empty, after VS Code reloads the tab's view
[VSCode] Fixed /btw side-question history from earlier sessions being overwritten when a question is asked right after a window reload or while a settings file has errors
[VSCode] Fixed the pending question card not reappearing after the Claude panel reloads when signed in with a Claude.ai or Console account
[VSCode] Fixed claude.ai-only features staying visible in a window's other Claude panels after one panel picked up a third-party provider from a settings file
[VSCode] Fixed the sign-in screen appearing despite the Disable Login Prompt setting when Claude Code reports no login or a request fails for lack of one
[VSCode] Fixed the next queued permission prompt keeping text typed on the previous prompt and accepting an immediate second click
[VSCode] Fixed install-plugin links opening the Claude sidebar without the install dialog in a window where only the session list had been shown
[VSCode] Fixed the sidebar usage meter staying empty on a new window until the Account & usage dialog was opened, and a 0% usage limit being left out of the meter
[VSCode] Fixed "Start new session in this group" losing the group after New conversation, and a missing unread dot for a session that finished before the sidebar's unread list loaded
[VSCode] Fixed the editor tab badge showing unread during a running turn or missing on a tab opened from the session list, and "Add Session Tab to Group" doing nothing for an archived session
[VSCode] Fixed "Enable Remote Control for all sessions" so flipping it also applies right away to sessions open in other VS Code windows
[VSCode] Fixed the session list's Open filter for sessions continued from claude.ai whose tab was still recorded under the web session, and labeled the filter menu's sections for screen readers
[VSCode] Changed the model picker to one flat list of every model, with rows kept for older model spellings listed last

v2.1.260 Sep 3, 2026

v2.1.260

What's changed

Added a diff panel that opens beside the conversation in fullscreen mode and shows your uncommitted changes as Claude edits; toggle it with /diff
Added a likely cause for prompt-cache misses (e.g. tool definitions or system prompt changed, idle past the TTL) to /cost and the status line's prompt_cache field
Added /reload-plugins to headless sessions, so it appears in the Claude Code Desktop and SDK command lists
Added a text form of /advisor (/advisor, /advisor <model>, /advisor off) for the desktop app, Remote Control, and other headless (-p/Agent SDK) sessions
Added oidc.scope_on_refresh to the Claude apps gateway for IdPs that return an id_token on refresh only when asked for openid again
Added Claude apps gateway support for newer Claude Desktop keys in desktop policy blocks, including userPluginMarketplacesEnabled and userPluginUploadsEnabled
Fixed Edit/Write/Read permission rules whose path contains parentheses being dropped as invalid or ignored by the Bash sandbox, which left "read-only" folders writable
Fixed one file permission rule with an uncompilable pattern (e.g. an unclosed [) making every file edit fail with Invalid regular expression; such a deny rule now guards the literal path it spells
Fixed Bash permission checks auto-approving zsh commands that hide a command substitution in a REPORTTIME, REPORTMEMORY or DIRSTACKSIZE assignment; these now prompt for approval
Fixed Bedrock model discovery, token counting and AWS SSO/STS credential calls failing with "unable to get local issuer certificate" when the corporate root CA is only in the OS certificate store
Fixed permissions.blockReadsOutsideWorkingDirectories on macOS hiding the user's git config from sandboxed git and hiding a worktree-isolated sub-agent's own checkout
Fixed managed settings not loading for claude.ai Enterprise/Team users who also had a leftover API key from an earlier /login
Fixed /status listing a signed-in claude.ai account and a configured API key as if both were in effect; the credential not in use is now marked
Fixed managed skillOverrides entries keyed on a bundled skill's alias (e.g. checkup for /doctor) not applying, and Skill(name) deny rules not covering a nested skill listed as <dir>:name
Fixed model: fable agents ignoring the [1m] tag on an ANTHROPIC_DEFAULT_FABLE_MODEL pin and silently running with a 200K context window
Fixed the /model picker not showing Fable 5.1 for organizations that can use it, which was only accepted when typed as /model claude-fable-5-1
Fixed prompt caching on Claude Fable 5.1 not covering the context attached after tool results, so it was re-sent as uncached input on every tool-call turn
Fixed model switching staying blocked for the rest of the session after a plugin hook load failure; each switch now re-checks and the refusal names the cause
Fixed model switching being blocked for the session when an organization-managed plugin's marketplace could not be loaded
Fixed SDK-provided MCP servers (e.g. Desktop connectors) sometimes missing from the first turn and only appearing on the next one
Fixed Claude in Chrome tools failing with "Not connected" mid-task in cloud-hosted claude.ai sessions when a connector was added or removed
Fixed flags, joined emoji and accented letters splitting across wrapped lines, and stale text staying on screen when a flag or joined emoji falls in the terminal's last two columns (now shown as …)
Fixed Remote Control accepting a model pick that is not a valid model name; it is now refused with an error instead of failing on the next message
Fixed /rewind and --rewind-files reporting success when checkpoint backup files were missing and nothing was actually restored
Fixed /rewind leaving stale file-read tracking from the rewound-away turns, which caused "File unchanged since last read" stubs and full-file re-injection after external edits
Fixed -p --resume/--continue (as used by the desktop app) failing on every retry once a session's worktree directory lost its git metadata; it now fails once, then resumes without the worktree
Fixed a subagent that resumed another agent via SendMessage never being woken by that agent's completion (the notification went to the main conversation instead)
Fixed agent teams: an in-process teammate's transcript losing messages, or going blank, during long API retry waits (e.g. under CLAUDE_CODE_RETRY_WATCHDOG) as retry notices evicted real messages
Fixed a session that moved to the background appearing twice in ListAgents (once as a phantom "interactive" twin with the same name) and receiving SendMessage deliveries in the viewer
Fixed intermittent "task output swap refused" errors when many sessions share a project directory
Fixed Ctrl+Z in fullscreen leaving the shell on the alternate screen, drawn over the paused interface
Fixed Workflow tool subagents being restarted as stalled while a long context compaction was still in progress
Fixed plugins from a URL marketplace failing to install with "marketplace entry path does not stay inside the marketplace directory" when a host app (e.g. Claude Desktop) stores it as a directory
Fixed an extra browser tab opening when an artifact is published in a session you're driving from claude.ai, the desktop app, or mobile (Remote Control)
Fixed the Artifact tool's first call failing with an "Invalid tool parameters" validation error in some Cowork sessions
Fixed IDE line selections being dropped when running a skill or slash command (the "N lines selected" context now reaches Claude)
Fixed repository detection for GitLab projects in nested subgroups (e.g. gitlab.com/group/subgroup/project)
Fixed owner/repo#123 issue references in rendered output linking to github.com when working in a GitLab repository; they now link to the gitlab.com issue
Glob/Grep: Fixed the search path being probed on disk before the permission check; a missing path is now reported after permission is decided, as Read does
Reverted the 2.1.259 change applying Read() deny rules to Bash arguments; it denied npm run build under a Read(./**/build/**) rule in every mode and made cd … && grep prompt even in auto mode
Improved structured output: Workflow agent({schema}) rejects a JSON Schema that can never be satisfied up front, and retry-cap errors now include the last validation failure
Improved deleting a background session whose worktree has unpushed commits: the message now names the branch and commit count, and deleting again discards the worktree
Improved the Claude apps gateway's refresh-failure log to name the step that failed
Improved idle CPU usage of non-interactive (-p / SDK) sessions
Improved the Claude apps gateway on Amazon Bedrock: input tokens for an aborted request are now counted with AWS's free CountTokens API (grant bedrock:CountTokens) instead of a one-token request
Improved the settings error for rules such as Edit(C:\dir\(name)\**), where \( is read as an escaped parenthesis rather than a path separator, to suggest an unambiguous spelling
Improved auto-compact for 1M-context models: Opus and Fable sessions now compact shortly before the 1M-token limit, and recovery compaction on very large contexts no longer times out at 10 minutes
Improved /ultrareview and claude ultrareview to wait up to 45 minutes (previously 30) for long-running cloud reviews
Improved /effort on Claude Fable 5.1 so changing effort mid-session no longer invalidates the prompt cache
Updated the bundled claude-api skill so its Go, Java, and C# samples use current-generation model IDs, and clarified that cheaper worker or sub-agent models should be current-generation too
Changed ctrl+l / cmd+k in fullscreen mode to clear the transcript view like a terminal clear; scroll up to see earlier messages
Changed permission rules with text after the closing parenthesis (e.g. Bash(ls) x), which never matched anything, to be reported as invalid settings instead of being silently ignored
Changed server-managed settings so a managed CLAUDE.md (claudeMd) no longer triggers the security approval dialog; hooks, shell-command, sandbox, and unsafe env settings still require approval
Changed Claude in Chrome to follow your organization's Claude in Chrome admin setting; when an admin turns it off, --chrome, /chrome and the browser tools are unavailable
Changed Claude apps gateway to send orgPluginSettings in the list form read by Claude Desktop 1.15200.0 and later; older desktops ignore it
Changed Claude apps gateway to also refuse to start, naming the field, when a desktop policy misspells a field in a nested object of a managedMcpServers or orgPluginSettings entry
Changed commands typed at the ! bash-mode prompt to run outside the sandbox even when strict sandbox mode (sandbox.allowUnsandboxedCommands: false) is on, like typing into your own terminal
Changed self-hosted runner --kill-session-after-min to release a session that is only waiting on its user (paused, resumable on the next message) instead of killing it and reporting a failure
Removed the one-hour time limit on background commands started by subagents; they now run until they exit or are stopped, matching the main session
[VSCode] Added the selected effort level to the footer model pill, fixed a stale effort level after switching models, and returned the footer pills to their earlier compact size
[VSCode] Added Open and Closed to the session list's status filter menu
[VSCode] Fixed the welcome screen disappearing in a new session when Remote Control turns on automatically
[VSCode] Fixed the session history picker loading a session a second time when it is already open in another tab; it now switches to that tab
[VSCode] Fixed the session tab's Rename command silently doing nothing while the tab's view was reloading; it now always applies
[VSCode] Fixed a half-finished message, an empty tool card or an extra "Thought for" line staying on screen after Claude Code retried a dropped response
[VSCode] Fixed "Enable Remote Control for all sessions" not applying to a session tab that was still starting when the toggle was flipped

v2.1.259 Sep 2, 2026

v2.1.259

What's changed

Added managedMcpServers managed setting: organizations can provide HTTP/SSE MCP servers to every user (same entry shape as .mcp.json); entries that name a command to run are skipped
Added --permission-prompts none for unattended headless hosts: anything that would prompt is denied automatically while the active permission mode (including auto mode) keeps deciding
Added recognition of glab mr create/merge/close/reopen/note/update so GitLab merge requests show as MR !N in the collapsed tool summary and refresh the footer MR badge
Added --json to claude plugin validate for a machine-readable validation report
Fixed concurrent sessions silently reverting each other's ~/.claude.json changes — workspace trust no longer resets and MCP/project state is no longer lost when running many sessions at once
Fixed a conversation whose thinking was rejected once being rejected again on every later turn
Fixed Bash Read() deny rules not covering files given as option values (--ignore-revs-file=.env, -f.env, @file), git diff/git grep file operands, or cd DIR && cat FILE compounds; grep -r/cp -r over a directory holding a denied file now asks
Fixed the prompt cache being invalidated when the OAuth token refreshed in sessions with telemetry disabled
Fixed fullscreen mode showing a blank conversation after a long turn with hundreds of tool calls
Fixed auto mode running a turn on a model it doesn't support when a command or skill's frontmatter model: named one; the turn now keeps the session model
Fixed CLAUDE_CODE_MAX_CONTEXT_TOKENS being ignored for Vertex-style model IDs (@YYYYMMDD suffix) of model versions Claude Code doesn't recognize
Fixed the live output preview of a running shell command hiding its newest lines when an earlier line wrapped
Fixed a background GitHub connection check that ran on every launch for claude.ai users; the result is now remembered across launches
Fixed --resume failing (and --continue opening an empty conversation) when a saved session contains an attachment entry with no payload
Fixed frontmatter model: on custom commands and skills being ignored in interactive sessions
Fixed Artifact publishing failing once with an "unexpected parameter note" error in conversations continued from an older version
Fixed managed forceRemoteSettingsRefresh being ignored at startup when a policy helper configured by MDM or the managed settings file had already run
Fixed worktree isolation refusing hook-created worktrees on machines where git rev-parse fails with a message other than "not a git repository"
Fixed OpenTelemetry metrics and events from cloud sessions missing the user.email, organization.id, and user.account_uuid attributes
Fixed MCP servers that disconnect while their tools are being listed at startup showing as connected with no tools instead of reporting the error
Fixed the file edit permission dialog sometimes showing a changed line cut short with no indication
Fixed repository detection dropping a known repo identity after a transient git probe failure
Fixed managed settings silently going unenforced when the managed-settings file, a drop-in, the MDM plist, or the HKLM value cannot be parsed: Claude Code now refuses to start and names the source
Fixed Stop not actually stopping background agents and workflows in remote-control sessions: killed tasks now stay visible and re-stoppable until their processes exit
Fixed resuming a workflow run while its previous stopped run was still exiting, which could run duplicate copies of its agents
Fixed marketplace repo URLs on github.com with a trailing slash or dangling ?/# producing an unusable .git clone URL
Fixed blocking Stop hooks causing the turn after a block to lose the model's reasoning from that turn and, on some models, miss the prompt cache
Fixed remote (claude.ai) sessions taking 60 seconds to start a turn after a browser-hosted MCP server's page had gone away
Fixed worktree-isolated sessions refusing common Bash loops, xargs pipelines and launcher-wrapped commands that cannot reach the main checkout
Improved terminal resize and first-render performance for long responses by reusing text measurements
Improved /workflows agent detail: JSON outcomes are pretty-printed with syntax colors and real line breaks, and long outcomes fold behind an expand toggle
Improved headless/SDK session start: the first turn begins up to 50 ms sooner when MCP servers finish connecting
Improved /install-github-app to explain it is GitHub-only and point to the GitLab CI/CD docs when run inside a GitLab repository
Improved nested background subagent results to be saved in the parent subagent's transcript, so resumed subagents keep them and shared transcripts show the delivery
Changed allowedMcpServers to govern only servers users add: a literal managed-mcp.json server your allowlist used to filter out now loads on upgrade; use deniedMcpServers to keep it off
[VSCode] Added an Active quick filter and a status filter menu (Needs input, Working, Completed) to the session list sidebar
Fixed remote and scheduled sessions doing nothing after a connector-tool permission prompt was approved while the session was paused

●

v2.1.258 Sep 1, 2026

v2.1.258

What's changed

Fixed Claude Code failing to launch on macOS 12 (Monterey), a regression introduced in 2.1.255
Fixed remote and scheduled sessions failing with "user messages must have non-empty content" after a re-sent permission approval could not be applied

●

v2.1.257 Sep 1, 2026

v2.1.257

What's changed

Added Claude Fable 5.1 (claude-fable-5-1), now the default Fable model — 1M context, $10/$50 per Mtok with $0.25/Mtok cache reads
Added "Time format" (timeFormat) and timeZone settings: 12-hour, 24-hour, 24-hour UTC, or a strftime pattern for the turn-end clock and transcript-view timestamps
Added a Containment Escape rule to auto mode so cloud metadata-credential fetches, egress evasion, and cross-tenant reach are no longer auto-approved unless your environment marks them expected
Added CLAUDE_CODE_SUBAGENT_MODEL_FORCE to apply CLAUDE_CODE_SUBAGENT_MODEL (or the main model) to every subagent, ignoring per-spawn and agent-definition model overrides
Added s in /effort to change effort for the current session only, matching /model
Added a /doctor warning for stale sandbox mask files left by a killed session
Added a one-time prompt in auto mode before the first file read outside the working directories, with the option to block such reads (permissions.blockReadsOutsideWorkingDirectories)
Added support for a gateway-supplied description on discovered /model picker entries (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY); entries without one still read "From gateway"
Fixed settings in a .claude/ folder created after startup not being picked up until restart
Fixed sessions dispatched from an agent view opened with ← always starting in the original session's permission mode, overriding the target directory's defaultMode and the agent's permissionMode
Fixed keybindings.json rebinds of Ctrl+G being ignored in claude agents; its Ctrl+S / Ctrl+T are now rebindable via the new Agents context
Fixed background sessions failing to start on macOS npm installs during a self-update, and on Windows when a stale daemon lock file pointed at a reused process id
Fixed the working spinner stopping while a response streams behind a slash-command panel
Fixed a background session's state.json detail repeating its own dispatch prompt after a scheduled wake-up
Fixed claude agents keeping a background session you re-prompted buried in Completed after it finished again; Completed now orders by the latest finish
Fixed claude --bg from a directory that was just deleted reporting "backgrounded" and leaving a crashed session row; it now prints the reason and exits 1
Fixed Remote Control connecting mid-session re-sending the Bash tool definition, causing a prompt-cache miss
Fixed a doubly-listed custom Authorization header overriding the configured credential on Bedrock, Mantle, Vertex, and WIF, and the Vertex setup wizard picking up a leftover Anthropic profile from ~/.config/anthropic
Fixed Claude apps gateway sending stray host Authorization or profile headers to Foundry, Vertex, and Bedrock, and Foundry Entra ID upstreams not starting when ANTHROPIC_FOUNDRY_API_KEY is set
Fixed a leftover Anthropic API key or auth token being sent alongside your Foundry subscription key in API-key mode
Fixed /schedule routines whose prompt was saved without a message role and then ran with nothing to do
Fixed claude agents not saying that a background session is waiting for you to approve a message from another session, or who sent it
Fixed a prompt stashed with Ctrl+S inside an opened background session being lost when the session went idle or was stopped and then reopened
Fixed telemetry (OTEL) settings pushed through server-managed settings being ignored on warm starts, including desktop-app Code sessions
Fixed a teammate permission request being answered twice when the leader's mailbox write was briefly locked
Fixed a phantom duplicate slash-command row rendering below the in-flight turn while a command's auto-continued response streamed
Fixed policyHelper timeoutMs and refreshIntervalMs values above the timer maximum (2147483647) causing failures or re-runs every millisecond; they are now clamped
Fixed the token counter freezing or crawling after switching to another subagent's transcript, and made background subagents' and teammates' counters update live while a response streams
Fixed sandbox network hosts written with a trailing dot (example.com.): a deniedDomains entry didn't block the host inside the sandbox, and "don't ask again" for such a host kept prompting
Fixed dismissing the Remote Control consent prompt (Esc, or n at claude remote-control) counting as consent, so the next request connected without asking
Fixed /mcp reconnect and enable still connecting a settings-file MCP server that a managed MCP allow/deny list or strictPluginOnlyCustomization loaded after startup should block
Fixed claude mcp remove leaving a remote server's stored OAuth credentials behind when strictPluginOnlyCustomization locks MCP to plugin-only servers
Fixed Remote Control (claude remote-control) sessions started from the Claude app ignoring the selected model and running on the machine's default instead
Fixed --disallowedTools and session deny rules being dropped after the first settings reload when allowManagedPermissionRulesOnly is enabled
Fixed --resume listing a backgrounded conversation twice and --continue reopening its stalled pre-background copy; --continue now also opens finished background sessions
Fixed fullscreen mode not letting you click ! shell command output to expand it
Fixed background sessions left running an older Claude Code binary piling up across auto-updates instead of being retired
Fixed claude agents --json briefly switching the terminal to raw mode and undoing another program's terminal settings on exit
Fixed Proactive output style sessions busy-looping with filler messages and repeated log reads instead of idling while a background command or Monitor they started is still running
Fixed subagents stopping when a response was cut off mid-stream by a computer sleep, dropped connection, or server error; they now automatically continue instead of ending with an incomplete response
Fixed ← doing nothing in the /btw panel inside a claude agents session: it now returns to the agents list (even mid-answer), and the panel comes back when you reopen the session
Fixed sessions with an advisor model set missing the prompt cache on background requests (compaction, /recap, prompt suggestions) and re-sending the full conversation uncached each time
Fixed claude -p exiting about 5 seconds after its final result while a Monitor the model armed was still running; it now waits for the watch to fire or time out
Fixed a permissions.ask rule being skipped in auto mode when the matching command ran inside a compound command or subshell, letting it run without the confirmation prompt
Fixed plugins being able to read files outside their own directory through a declared command, agent, skill, hooks or other component path that is a symlink; such paths are now refused with an error
Fixed /add-dir rejecting a directory inside the current working directory; it now loads that directory's skills, commands, and agents like --add-dir does at startup
Fixed the main agent not being told when you resume a subagent you had stopped from its transcript view
Fixed a crash when pasting ANSI-colored text (e.g. a CI log) into dialogs like /feedback
Fixed claude mcp add/remove hanging or exhausting memory when the project's .mcp.json is a FIFO or a device-file symlink; it now fails fast with an actionable message
Fixed unbounded memory growth when non-JSONL data is piped into claude -p --input-format stream-json; it now fails fast with a clear error
Fixed backgrounding a turn (← or Ctrl+B) while a subagent or other tool was running occasionally making the background session treat that tool as rejected instead of re-running it
Fixed Bash Read()/Edit() deny rules not applying to < file redirects and reader commands like tac and egrep; a deny rule on any argument or redirect target now refuses the command
Fixed resuming or messaging a subagent whose transcript had grown past 5 MB (for example after reading many images) failing with "No transcript found"
Fixed worktree-isolated sessions refusing Bash loops, $VAR reads, "$(…)" and heredocs that never touch git as "too complex to verify that it stays inside the worktree"
Fixed /model and /effort showing a prompt-cache warning after rewinding a conversation back to empty
Fixed prompt-cache misses on every turn in long screenshot-heavy sessions once images exceeded the per-request size cap
Fixed the Edit permission prompt's diff view rendering emoji and multi-code-point characters with incorrect widths
Fixed WebSocket MCP server connection failures being logged as "[object ErrorEvent]" instead of the underlying error
Fixed background sessions failing to open with "Couldn't start the background service" while another Claude Code process was downloading an npm update; the start now waits for it
Fixed background commands that detach from their shell (for example under timeout or setsid) surviving a task stop or Claude Code exit
Fixed Claude not being told when you stop a background command from the tasks panel or a connected client
Fixed stopping a background subagent leaving its monitors running
Fixed sandboxed git commands in a linked worktree losing write access to the repository's common .git directory after cd into a subdirectory
Fixed Bedrock and Bedrock Mantle requests going silent during long hidden-thinking phases on Opus 4.7 and later, which let idle timeouts cut the connection; the stream now carries progress events
Fixed launching Claude Code after a Claude apps gateway expired or revoked your session: it now says the session ended and offers /login instead of reporting a network error
Fixed cloud sessions losing git/GitHub credentials for the rest of the session when the session's network proxy failed to start at launch; it now retries in the background and recovers
Fixed leftover cc-daemon-* folders in the system temp directory after an interrupted background daemon start; the cleanupPeriodDays retention sweep now removes them
Fixed Bash permission checks auto-approving certain [[ ]] conditionals that zsh parses differently from bash; these commands now prompt for approval
Fixed the managed-settings approval prompt showing the generic warning instead of its telemetry wording when the settings also turn detailed tracing or raw API body logging off, or trace export on
Fixed agent-team teammates in tmux/iTerm2 panes sometimes staying open after acknowledging a shutdown request
Fixed the keyless Console sign-in ("Sign in with your Console account") not applying your organization's server-managed settings, and /status not showing the Organization for that sign-in
Improved rendering performance: less re-render work per turn in long conversations, streaming no longer slows down as the reply grows, and background-agent updates no longer re-render the whole screen
Improved prompt input responsiveness by reducing per-keystroke rendering work
Improved policy helper diagnostics — refresh failures now show in /status, declining the managed-settings dialog prints why Claude Code exited, and helper timeouts are reported as timeouts
Improved /code-review --comment to post findings on GitLab merge requests via glab mr note instead of reporting the target as unsupported
Improved notifications: an MCP elicitation or permission ask queued under another dialog now sends its idle desktop notification at the same delay as a visible ask
Improved verbose/transcript output: async hook completion notices that arrive together now appear on one line instead of one line per hook
Improved claude self-hosted-runner --configure-git to also enable git push negotiation, so the first push of a new branch from a stale clone uploads only the new commits instead of the whole tree
Improved liveness reporting to SDK hosts while a response is held open by gateway keep-alives, so long waits under a raised CLAUDE_STREAM_IDLE_TIMEOUT_MS are not mistaken for a hung session
Improved MCP connection and OAuth debug/error logs so credentials carried in a server's URL or request headers are redacted
Improved /fork to keep the original conversation's prompt cache in the new background session: its worktree briefing now arrives as a message instead of a system-prompt change
Improved emoji autocomplete to accept the remaining GitHub/Slack shortcode aliases (:satisfied:, :telephone:, :collision:, …)
Changed --effort to lift a new model's default-effort hold for that session only rather than permanently; an effort picked on claude.ai for a Remote Control session now applies during the hold
Changed a policyHelper in MDM or managed-settings.json shadowed at launch by cached server-managed settings to run (or exit) as soon as the fetch reports them removed, not at the next launch
Changed managedSourcesBehavior: "merge" to take sandbox.credentials.awsPairs and sandbox.ripgrep whole from the highest managed source that sets them instead of combining the sources' values
Changed gateway model discovery (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1) to run even when CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC is set, since it only queries your gateway
Changed claude --resume <session-id> --bg to continue that session under its own ID when nothing is running it, instead of silently starting a copy; a copy is now announced
Changed /btw history browsing from ←/→ to Shift+←/Shift+→ (or [/]), stepping through your recent side questions and back to the live answer
Changed defaultMode: "bypassPermissions" in .claude/settings.json or .claude/settings.local.json to be ignored, like "auto"; set it in user or managed settings, or pass --permission-mode
Changed fable and best in Claude apps gateway sessions to keep resolving to Fable 5 for now, since gateways not yet configured for Fable 5.1 reject it; pick Fable 5.1 in /model to use it
Changed --add-dir, /add-dir, and additionalDirectories to refuse network paths (UNC shares, /net/<host> automounts) with a message before touching them; on Windows use a mapped drive letter
Changed Claude apps gateway sign-in and token refresh requests to verify the gateway's pinned TLS certificate, as the managed settings fetch already does
Changed Cowork and claude.ai cloud sessions: reading an artifact that isn't yours now always asks you first, even in auto mode
Removed the Ctrl+E command explanation on Bash and PowerShell permission prompts
[VSCode] Added collapsible ACCOUNT & USAGE and SESSION MANAGER section headers to the session list panel, with the account email, the usage meter, and a View details link opening the usage dialog
[VSCode] Added a model pill to the input footer that shows the current model and opens the model picker, with an Effort row and a "More models" page
[VSCode] Added a collapse toggle to the Ungrouped section of the session list
[VSCode] Added output style selection to the command menu, including custom styles
[VSCode] Fixed third-party provider deployments (Bedrock, Vertex, and others) still showing claude.ai-only features (remote sessions, dictation, usage) and calling claude.ai with a leftover login
[VSCode] Fixed the session list panel's usage meter staying blank after the panel loads; it now shows the last known usage immediately
[VSCode] Fixed the "Enable Remote Control for all sessions" toggle so turning it on or off applies to sessions that are already open, not only to new ones
[VSCode] Fixed screen reader announcements: a control character before a fence or heading no longer drops visible lines from speech, and bold markers spanning a heading are no longer mis-paired
[VSCode] Changed the action menu to list slash commands in a filterable "Slash commands" dialog instead of inline; picking one runs it; the MCP servers dialog gained the same filter box
[VSCode] Changed "Delete session" to "Archive session": archived sessions move to a collapsible "Archived sessions" group at the bottom of the list with an Unarchive action

v2.1.252 Aug 31, 2026

v2.1.252

What's changed

Fixed Bash commands failing with "task output swap refused (tasks dir moved or linked)" on some Macs
Fixed "always allow" not saving in a project that has no .claude/settings.local.json yet

⚡

v2.1.251 Aug 28, 2026 Breaking

v2.1.251

What's changed

Added PreModelSwitch and PostModelSwitch hook events (block, confirm, or annotate a model switch); SessionStart resume hooks now receive session staleness and the estimated re-cache cost
Added live streaming of a foreground subagent's tool calls and results to Remote Control clients (background subagents, the default, still show status only)
Added a Spend limit bar to /usage and a rate_limits.spend_limit status line field for developers behind a Claude apps gateway with spend limits
Added a per-session prompt-cache line to /cost (hit ratio, misses, tokens re-cached, warm/cold) and a matching prompt_cache object for status line scripts
Added attach, logs, stop, respawn, and rm to claude --help; the --resume message for a running background session now names the exact claude attach <id> command
Fixed file tools (Read, Write, Edit) following a symlink swapped inside the working directory after the permission check, which could read or write outside the approved location
Fixed plugin commands declared in a marketplace entry being able to point outside the plugin directory; such paths are now rejected with a path-traversal error
Fixed project settings being able to enable detailed beta tracing or raw API body logging, and a lower-scope beta tracing endpoint bypassing an OTLP collector pinned by managed settings or a host app
Fixed the Workflow tool reading (and quoting in errors) a scriptPath outside what the session may read before the permission check ran
Fixed Grep and Glob not applying Read(...) deny rules to files reached through a symlinked search path
Fixed conversations getting stuck on "text content blocks must be non-empty" errors after a turn where the model produced only thinking
Fixed the first launch on a fresh install starting in default mode instead of auto mode for accounts whose startup default is auto mode
Fixed Opus 5 requests failing with "effort … is not supported when thinking is disabled" when effort was xhigh/max and thinking was turned off; effort is now sent as high in that case
Fixed replying to a message Claude Desktop delivered from another session: SendMessage to that session id now delivers through Claude Desktop instead of failing with "not reachable"
Fixed TUI lag with many parallel subagents: per-second progress ticks now replace their predecessor instead of piling up in the transcript
Fixed agent teams: a teammate's final answer not reaching the team lead — it now arrives in the idle notification instead of a content-free "available" notice
Fixed background subagents being unable to reply to a message from an unnamed sibling or parent agent (from was the agent type, which is not an address)
Fixed managed-settings disableAutoMode arriving mid-session not moving an already-running auto-mode session back to default mode
Fixed a "switch to Opus 1M for 5x more context" tip that appeared even when the current Opus model already has a 1M context window
Fixed Claude apps gateway sessions treating a stored Anthropic profile (e.g. a Console sign-in) as active: listing it in /status and retrying gateway 401s with it, though requests never use it
Fixed cloud sessions telling Claude the model had changed when the host was only setting the session's initial model
Fixed Remote Control reporting a failure when an organization's policy disables it; it now shows a single quiet notice instead
Fixed /mcp reconnect on Remote Control showing a generic withheld-detail error instead of the real remedy when a server was disabled in another session
Fixed --input-format stream-json: client-injected assistant tool calls sent without a message id were merged into the first one and their results lost, including when resuming older sessions
Fixed session transcripts being silently overwritten when a directory change relocated a session onto an existing same-ID transcript
Fixed background sessions and their subagents being unable to edit files inside a git worktree they created with git worktree add
Fixed background sessions occasionally starting without any plugin skills (and staying that way) when another Claude Code process was refreshing the plugin marketplace at the same moment
Fixed selecting text in an opened background session inside tmux over SSH: it now copies to the tmux buffer like a foreground session instead of falling back to OSC 52
Fixed SDK and cloud sessions hanging indefinitely when an SDK MCP server's handshake acknowledgment was lost; the wait now times out after 70 seconds and marks only that server failed
Fixed self-hosted runner leaving a stuck session's Bash tool processes running after the session was force-stopped
Fixed /usage-credits for Team and Enterprise members whose admin set the org's usage-credit limit to $0: it now offers to ask the admin instead of saying a cap was reached
Fixed --worktree --tmux with a merge-request number on a gitlab.com origin trying a doomed GitHub-style fetch first instead of fetching the GitLab ref directly
Fixed Ctrl+G failing with "Emacs quit unexpectedly" in background sessions for editors that open /dev/tty, such as emacs -nw and micro
Fixed an additionalDirectories entry containing a null byte crashing startup, or breaking /add-dir and later settings updates when it came from an SDK host, IDE, or hook; it is now skipped
Fixed the MCP server menu's copy shortcut: it now says how the sign-in URL was copied instead of always claiming success
Fixed italic text (such as the session recap line) rendering as highlighted blocks in GNU screen and in tmux sessions using a screen terminal type
Fixed claude mcp add --header and claude mcp add-json help text naming the wrong transports
Fixed claude ultrareview and /ultrareview waiting the full 30 minutes when the cloud session fails to start; they now stop early and report the reason
Fixed Bash permission checks auto-approving commands that assign an arithmetic expression to an integer shell variable (e.g. OPTIND=1/0, RANDOM=2+2); these now prompt for approval
Fixed backgrounded sessions (←, /background, --bg) losing a Vertex/Bedrock gateway (ANTHROPIC_*_BASE_URL + CLAUDE_CODE_SKIP_*_AUTH) exported in the shell, so every request failed
Fixed claude --bg --model fable on Max plans stopping to ask for usage credits while the interactive session on the same account still had Fable allowance
Fixed the one-time "make auto mode your default" offer appearing in unattended sessions (e.g. agent-team teammate panes), where a stray keypress could accept it unread
Fixed the managed-settings approval prompt re-appearing after signing in again to the same Claude apps gateway when the settings are unchanged
Fixed disabled /bug and /share reporting that /feedback was disabled; tips, /help, and refusal messages no longer suggest /feedback when an org policy or env var turns it off
Fixed cloud session creation advising GitHub setup after a transient GitHub connection failure — the message now says to retry instead
Improved CPU usage during turns in interactive sessions by cutting redundant UI re-renders
Improved install size: the native binary is about 5 MB smaller
Improved cloud sessions: when the session's network proxy drops a connection during a Bash command, the tool result now names the host and reason instead of only "connection reset"
Improved /schedule to explain that MCP servers configured in Claude Code can't be attached to cloud routines, instead of a bare "No MCP connectors" message
Improved framing of messages from your own subagents: Claude is told the sender is a worker inside this session, not an unrelated Claude session
Improved the prompt placeholder to read "Message @name…" while viewing a background subagent or fork transcript opened from the subagent panel or /tasks
Improved sanitization of MCP server names in error messages, menus, and command results
Improved Amazon Bedrock session start under CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST (e.g. Claude Desktop): a session given a Bedrock model ID or ARN no longer waits for inference-profile discovery
Improved the managed settings approval dialog to list only the settings that changed since you last approved them
Improved retry when the model's tool call is malformed: the broken output is now dropped from the retry context, including on Bedrock, Vertex, and Foundry
Changed /radio to be available on Bedrock, Vertex AI, Foundry, and Claude Platform on AWS, and when telemetry is disabled
Changed Claude in Chrome so browser actions always go through Claude Code's permission checks, including in sessions with telemetry disabled, which previously used the Chrome extension's own prompts
Changed CLAUDE_CODE_SUBAGENT_MODEL to set the default subagent model rather than override everything: an agent definition's model: and an explicit per-spawn model now take precedence over it
Changed the default commit trailer to Co-Authored-By: Claude Code when the active model isn't a recognized Claude model (e.g. third-party models behind a custom ANTHROPIC_BASE_URL)
Changed the default model for seat-based Enterprise subscriptions to Opus 5, matching other premium plans
Changed /effort to save your default effort level per model, so each model keeps its own setting when you switch
Changed analytics to no longer turn off before sign-in solely because managed settings force gateway login (or cannot be read); they stay off once signed in to the gateway or via DISABLE_TELEMETRY
Changed the footer PR badge on Bedrock, Vertex, and Foundry, and when telemetry is off, to call the GitHub API directly (via gh auth token, GH_TOKEN, or GITHUB_TOKEN) instead of gh pr view
Changed how Bash command output files are created and read back when commands run in the sandbox, so a sandboxed command cannot redirect or replace them
Changed plugin/LSP install suggestions and the auto-mode default offer to wait until you've sent or cleared what you're typing, so the Enter that sends your prompt can't answer them
Changed server-managed settings that terminate sandbox TLS, route sandbox traffic through your own proxy, inject credentials, or weaken sandbox isolation to require approval before they apply
Changed ANTHROPIC_CUSTOM_HEADERS from managed or project settings to require approval when it sets a credential, org/tenant, routing, or API-behavior header (e.g. Authorization, Host)
Changed project-level .claude/settings.json env to no longer set CLAUDE_CONFIG_DIR, CLAUDE_CODE_TMPDIR, or TMPDIR/TMP/TEMP; set them in your shell, user, or managed settings instead
Removed syntax highlighting for six rarely used languages (1c, gml, isbl, mathematica, maxima, sqf); the binary is 2.5 MB smaller
[VSCode] Fixed the sign-in screen's "Bedrock, Foundry, or Vertex" button opening the docs at the top of the page instead of the third-party provider setup section
[VSCode] Changed the Remote Control banner to a footer pill (shown while Remote Control is on or has failed) that opens the session on claude.ai/code; turn it on or off with /remote-control

v2.1.248 Aug 27, 2026

v2.1.248

What's changed

Added --restricted (or CLAUDE_CODE_RESTRICTED=1): removes the built-in tools that run commands or code and WebFetch (unless named in --tools), keeps file tools inside the working directory, refuses bypassPermissions, and ignores user, project and local settings files
Added experimental.cacheTtl ("5m" or "1h") to agent frontmatter: a per-agent prompt cache TTL used when no subagent TTL setting is configured
Added claude self-hosted-runner --client-label <label> (or SELF_HOSTED_RUNNER_CLIENT_LABEL) to override the label the runner registers with (default: hostname)
Added server-managed settings diagnostics: a startup warning when the settings fail to load, and a /doctor and /status line explaining a load failure or why they weren't fetched (Bedrock/Vertex/third-party provider, custom ANTHROPIC_BASE_URL)
Added a warning in /web-setup when the GitHub CLI token lacks the workflow scope, since pushes to very large repositories can be rejected without it
Added /usage-credits for Enterprise organizations billed through AWS Marketplace, self-serve Enterprise, and Enterprise trials, so members can request a higher usage limit from their admin
Added cross-session messaging (SendMessage / ListAgents) between sessions on the same machine on Bedrock, Vertex, and Foundry, and when telemetry is disabled
Fixed a prompt-cache miss (and lost extended-thinking context) roughly once an hour in long sessions, caused by tool definitions being re-rendered after an OAuth token refresh
Fixed the ScheduleWakeup tool definition changing between a session and its --resume when the account had entered usage overage, causing a full prompt-cache miss on the resumed session's first turn
Fixed Claude Desktop and Cowork sessions disappearing after 30 days: the transcript cleanup now keeps desktop-written sessions while they are in the app (unless org policy manages retention); the new desktopSessionCleanupPeriodDays setting caps the exemption
Fixed being sent to the login screen when another Claude Code process held the token refresh lock while the session token had expired; the request now fails with a retryable error instead
Windows: Fixed the claude agents list not responding to the keyboard after detaching from a session, or when launched in a terminal tab left in win32-input-mode
Fixed the recommended Console sign-in in /login failing with an OAuth error before showing a sign-in URL on machines where it can't be used (for example when ANTHROPIC_API_KEY or an API key helper is set); it now falls back to the API-key sign-in
Fixed model names in /model and fast-mode switch notices to render as code, so suffixes like [1m] display literally instead of as a link
Fixed claude agents skipping the workspace trust prompt when the CI environment variable is set
Fixed claude agents crashing on launch when the PR-status cache held a malformed entry
Fixed agent view resurrecting a weeks-old background session after the machine was off: such a session now shows as stopped at its real end, and opening it asks before resuming its saved conversation
Fixed agent view sometimes opening an older conversation, and dropping the typed prompt, when starting a new session
Fixed claude agents: opening a stopped session that you already resumed in another terminal no longer starts a second process on that conversation; the row now says it is open in a terminal
Fixed claude agents and claude rm refusing to delete a session ("has commits that are not pushed anywhere") when its worktree branch was already merged into your checked-out default branch (e.g. local main) but not yet pushed
Fixed background sessions waiting silently when a PermissionRequest or PreToolUse hook prints an invalid answer: the claude agents row now names the hook and the schema error
Fixed hooks silently treating a stdout {…} object that isn't valid JSON as plain text; it's now reported as a hook error with the parse message
Fixed /mcp listing a project .mcp.json entry that declares the claude.ai connector type under the trusted "claude.ai" heading; it now appears under its real scope
Fixed MCP servers whose headersHelper supplies the Authorization header falling into OAuth discovery on a 401 instead of re-running the helper and retrying the call as documented
Fixed /login to a Claude apps gateway hanging when the managed-settings security approval dialog was required
Fixed gateway model discovery (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY) never running when apiKeyHelper is the only credential
Fixed claude logs leaving mouse tracking, bracketed paste and the alternate screen switched on in the terminal it was run from
Fixed the trust dialog's list of repo permission rules showing a garbled character when a long rule was cut off in the middle of an emoji
Fixed the permission mode indicator staying hidden behind the "Press Ctrl-C again to exit" hint when you press shift+tab right after ctrl+c
Fixed /ultrareview and locally seeded cloud sessions uploading uncommitted edits to prod.env-style and *.tfvars files, or to editor swap, temp, and backup copies of credential files (e.g. key.pem.tmp, id_rsa.swo); they now stay on your machine
Fixed Remote Control sessions occasionally never showing a permission prompt or the latest messages on the connected device after the CLI silently reconnected
Fixed cloud sessions occasionally failing at startup when the container's session credentials were not yet readable
Fixed claude remote-control rejecting its own flags (e.g. --spawn, --name) when a global flag or a wrapper-injected option precedes the subcommand
Fixed startup warnings (e.g. "N MCP servers need authentication") rendering one column right of the rest of the transcript
Fixed a backgrounded worktree session losing its checkout: the background session now holds the worktree's lock while it runs, so cleanup and git worktree remove leave it alone
Fixed @-mentions of other sessions not matching names typed with non-Latin characters (for example Korean entered through an IME)
Fixed an invalid crossSessionInbound value being silently ignored: it now warns and holds cross-session messages (user settings) or refuses them (managed settings) until fixed
Fixed rate-limit, usage, and fast-mode messages telling you to run /usage-credits when that command isn't available for your organization (e.g. hidden with DISABLE_EXTRA_USAGE_COMMAND)
[VSCode] Fixed a chat tab getting stuck on "No conversation found" when its session was never saved; it now starts a new conversation instead
Improved the Workflow tool's prompt footprint: its description is now about 1k tokens instead of 5.7k, with the script-writing reference moved into a bundled workflow-authoring skill
Improved the prompt-footer PR badge to check GitHub less often while the pull request is unchanged; a push or a gh pr command still refreshes it right away
Improved managed settings: client-side timeout, MCP startup-mode, and stream-watchdog env vars no longer trigger the settings-approval prompt
Improved /ultrareview <PR#> to check before launch that the GitHub account connected to your Claude account can access the repository, and to explain how to fix it, instead of failing after the cloud session starts
Improved cross-session messaging: falls back to a private per-user /tmp directory when the default one can't be used, and the notice and /status name the directory to fix
Changed shift+enter in the agent view dispatch input to insert a newline (matching the prompt); ctrl+enter now dispatches and attaches
Changed /loop: self-paced dynamic mode and the no-prompt autonomous default are now always available, including on Bedrock/Vertex/Foundry
Changed Anthropic telemetry export failures to log at debug level as [Anthropic telemetry] instead of [3P telemetry] OTEL diag error, so they are not mistaken for your OTel collector failing
Changed cross-session messaging in Linux user namespaces: root-equivalent trust for unmapped owners is limited to canonical system directories
Changed SendMessage from a subagent to another session: the result now notes that any reply is delivered to the parent session's conversation, not to the subagent

●

v2.1.247 Aug 26, 2026

v2.1.247

What's changed

Added the SendFeedback tool: when something goes wrong in a session, Claude can draft a feedback report for you to review and send from /feedback (turn off with the feedbackDrafts setting)
Added {id, text, cooldownSessions, priority} entries, tipsFile, and label to spinnerTipsOverride, so organizations can rotate their own tips alongside the built-in ones
Added a tip on Bash permission prompts pointing to auto mode, with a one-keystroke "Yes, and switch to auto mode" option
Added /claude-api cost-optimize to profile an existing project's Claude API spend and work through cost levers (caching, token hygiene, batch, effort, model choice) one measured change at a time
Updated the /claude-api skill with Admin API coverage (organization members, invites, workspaces, API keys, rate limit reports, workload identity federation, CMEK)
Fixed fast arrow-key + Enter sequences acting on the row above the one you navigated to in history search, /config, /mcp, /skills, background tasks, and /model
Fixed sub-agents dying on a first-call model 404: they now use the session's fallback model chain, and the error returned to the parent includes the error type, status, request id, and model
Fixed a hook or background agent that printed megabytes of error output being able to overflow the conversation and wedge the session on "Prompt is too long"
Fixed Ctrl keyboard shortcuts not firing under non-Latin (e.g. Cyrillic) keyboard layouts in kitty-protocol terminals
Fixed text like <35;150;7M being inserted into the prompt when a mouse report arrived split across reads right after the escape prefix
Fixed the Bash sandbox's after-command cleanup deleting a dotfile-managed ~/.claude/settings.json symlink (nix/home-manager, stow) when it is repointed outside the sandbox's writable area
Fixed /terminal-setup overwriting your entire Zed keymap.json instead of merging in its keybinding
Fixed /rename silently confirming when the session registry could not be updated; it now says other sessions may still show the old name
Fixed /compact and "Summarize from here" in sessions started with --agent summarizing under the default system prompt instead of the conversation's own
Fixed a background session showing "opening…" forever in claude agents after its terminal host process died; the row now fails within seconds with the reason, and Enter restarts it
Fixed unbounded memory growth when a hook's or background task's output file could not be written; the file now notes where output was lost
Fixed /install-github-app over SSH: the copy shortcut now says how the sign-in URL was copied instead of always claiming success, and the URL appears immediately when no browser can open
Fixed shell commands carried over from the foreground logging an internal error or showing a misleading [exited with code -1] line when they finish in background sessions
Fixed a version-less marketplace plugin's live cache directory being deleted and recreated on a second-scope install, which could disrupt a running session using it
Fixed Remote Control sessions started with /remote-control not reporting the working-tree diff to connected clients
Fixed self-hosted runner sessions reporting running before Claude Code had started, which could trigger a premature "Claude is waiting for your input" notification from the Claude desktop app
Fixed first-run setup exiting with "Unable to connect to Anthropic services" when managed settings configure Claude apps gateway sign-in and Anthropic endpoints are unreachable
Fixed cloud sessions (Claude Code on the web, desktop and mobile apps) sometimes showing the previous permission mode when you switch modes right after sending a message
Fixed cloud sessions going silent when the session's container restarts between turns while a background agent, shell, or monitor is still running — the resumed session now reports the lost work
Improved plugin marketplace hardening: names containing control or invisible characters are rejected, and marketplace-supplied text in /plugin and claude plugin output is escape-safe
Improved Bedrock, Vertex, and Foundry sessions (and any with telemetry disabled): Claude is now told when a configured MCP server failed to connect, instead of concluding its tools don't exist
Changed Sonnet 5's default auto-compact window to its full 1M context, so sessions on the 1M window now auto-compact at about 967K tokens instead of about 934K
Changed cross-session peer messages to collapse by default to a one-line Message from @<sender>: <first line> preview; Ctrl+O expands the full body
Changed terminal hyperlinks in rendered markdown: link targets that point at a network or automounter path, contain a control character, or lead with an invisible character now render as plain text
Changed the prompt-footer PR badge to skip its GitHub re-check on terminal refocus when the last check is under a minute old
Changed analytics to stay off from startup, not only after login, when managed settings force gateway login or a custom OAuth deployment is configured
Changed Claude apps gateway sign-in requests to identify Claude Code (a surface=claude_code device-authorization parameter and a claude-code/<version> User-Agent)
Changed organization sign-in enforcement to exit at start when the administrator's managed settings cannot be read, even if host-supplied or per-user Windows registry settings exist

v2.1.246 Aug 25, 2026

v2.1.246

What's changed

Added a startup warning for Bash allow rules with a wildcard before the subcommand (e.g. Bash(git * main)), since they also match options inserted before the subcommand
Added an Auto mode tab to /permissions for viewing and editing auto mode classifier rules
Added the turn's completion time to the end-of-turn duration line, e.g. ✻ Sautéed for 23s · done 6:05 PM
Fixed fullscreen mode showing a blank transcript after resizing the terminal and jumping to the bottom until the next keypress
Fixed a severe transcript slowdown when a diff contained a very long single line (e.g. a base64 string); such lines now render truncated with a marker
Fixed erratic fullscreen scrolling when positioned at an earlier message, including jump-to-bottom getting stuck mid-transcript
Fixed background sessions failing to open after 45 seconds when Claude Code's starting directory had been deleted, the machine had slept, or the host is slow to start processes
Fixed background sessions failing to open with "Couldn't start the background service … EACCES" when another Claude Code process was re-installing the npm package at that moment
Fixed markdown rendering being disabled for a whole message when its first 500 characters contained no markdown, and for +/N) lists and setext headings
Fixed MCP tool calls interrupted by an incoming message in headless/remote sessions being reported to the model as "completed with no output" instead of an explicit interrupted error
Fixed MCP tool arguments being sent as JSON strings when the parameter's schema is empty ({}), instead of their real type
Fixed a command interrupted mid-run showing as "Ran 1 shell command" with no sign it was cut
Fixed pressing ← or running /background during a dynamic workflow restarting its finished subagents; it now asks first and says how many subagents would restart
Fixed opening a just-started session in claude agents while its worker was still booting (common on Windows) stopping it with "was stopped while the respawn was in flight"
Fixed claude agents listing a backgrounded named session twice; backgrounding the same conversation again now numbers the new row (e.g. my-session (2))
Fixed the background retention sweep removing git worktrees under .claude/worktrees/ that you created yourself when an old background-session record pointed at them
Fixed auto mode tool calls being denied as "temporarily unavailable" on very large sessions by scaling the safety-check deadline with prompt size
Fixed the plugin cache creating duplicate SHA-named directories for the same plugin
Fixed plugin skills whose frontmatter name already includes the <plugin>: prefix showing it doubled in the slash menu (e.g. /plugin:plugin:skill)
Fixed claude plugin update failing for an installed plugin given its bare name (only the fully-qualified name worked)
Fixed plugin installation failing when plugin.json was saved with a UTF-8 byte-order mark (BOM)
Fixed /reload-plugins reporting 0 skills for plugins that define skills under skills/*/SKILL.md
Fixed hook error messages showing a literal ${CLAUDE_PLUGIN_ROOT} instead of the resolved plugin path
Fixed /rename replacing the theme's prompt border color (including a custom theme's promptBorder) with the default cyan; the border now keeps your theme's color unless you pick one with /color
Fixed custom theme diff colors (diffAdded/diffRemoved and their dimmed variants) being ignored in diffs and the /theme preview
Fixed a keybindings.json binding with an unknown action name silently deadening that key; it is now skipped so the default binding keeps working, and a warning is logged under --debug
Fixed /stats activity heatmap showing each day's activity one cell off (Sunday's count under Monday) in timezones east of UTC
Fixed /fork from an already-forked or backgrounded session starting the new session with an empty conversation
Fixed prompts beginning with /-- (e.g. Lean doc comments) being rejected as an unknown slash command instead of being sent to Claude
Fixed the @ file picker staying open after the typed text stopped matching a real path
Fixed the status line's cost and duration resetting to zero after navigating to the agents view and back
Fixed fullscreen mode moving keyboard focus onto the control under the pointer when you clicked the terminal window only to bring it back into focus
Fixed path completion failing when the completion token or working directory contained a null byte
Windows/macOS: Fixed headless sessions not cleaning up stale entries in ~/.claude/sessions left by sessions that exited uncleanly
Fixed the UI stopping with a render error on the first tool call when a third-party Anthropic-compatible endpoint (ANTHROPIC_BASE_URL) streams a tool_use block without an id
Fixed the Write tool reporting "Out of memory" or freezing for a long time after overwriting a very large existing file, even though the file had been written
Fixed claude plugin install <name> exiting silently (or hanging in a terminal) instead of reporting an error when ~/.claude/plugins/known_marketplaces.json is empty or corrupted
Fixed resumed sessions failing every turn with a 400 when the saved history contains tool blocks the Anthropic API does not accept (typically written by a third-party API proxy)
Fixed curl -fsSL https://claude.ai/install.sh | bash failing with "Raw mode is not supported" for some Team/Enterprise users with server-managed settings
Fixed sessions that ended in plan mode resuming outside plan mode in the VS Code extension, and in claude -p --continue/--resume with a permission prompt tool, when no permission mode was set
Fixed the Notification hook not firing while the sandbox "Network request outside of sandbox" permission prompt is waiting
Fixed Bash permission checks to always require approval for malformed commands with a dangling && or || operator
Fixed --strict-mcp-config sessions prompting to approve .mcp.json servers they would never load, which left background sessions waiting at startup
Fixed telemetry and metrics requests to Anthropic carrying the API key configured for a third-party gateway (ANTHROPIC_BASE_URL); a credential is now only sent to its own host
Fixed a visible API error on the first prompt after idle when apiKeyHelper returns short-lived JWTs: an expired cached token is now refreshed before sending, and 401/403 auth errors retry quietly
Fixed memory growing with session length in the fullscreen and Ctrl+O transcript views: each rendered message row no longer retains a full copy of the transcript-wide tool lookups
Fixed /ultrareview runs and cloud sessions launched at the same time from one repository (e.g. from several worktrees) sometimes starting with another launch's uncommitted changes
Fixed the task progress count (e.g. 3/5) shown for background cloud sessions such as /autofix-pr occasionally missing a task
Fixed Remote Control sessions keeping their placeholder name in claude.ai and the Claude app until the second prompt; the auto-generated title now appears after the first prompt
Fixed MCP tools marked requiresUserInteraction still offering "Yes, and don't ask again" in their permission prompt; the option wrote an allow rule the tool then ignored
Fixed the self-hosted runner ending its live sessions or exiting when a work-poll response is malformed (e.g. an intercepting proxy's HTML page); it now retries the poll
Improved /cd: the new directory's project settings, hooks, .mcp.json servers (behind the usual approval prompt), skills, and agents now take effect right after the move instead of on --resume
Improved Bash tool latency on bash shells by replaying snapshot functions without a base64 subshell per function
Improved subagent results: a subagent that stops at its maxTurns limit now returns its output marked as partial, with a hint to continue it via SendMessage, instead of appearing finished
Improved non-interactive sessions (-p, SDK, cloud sessions) to automatically continue a response cut off mid-stream by a server error, connection loss, or stall instead of ending with an error
Improved attribution of usage telemetry to your organization for workload identity federation sessions, events sent while apiKeyHelper runs at startup, and after a login token expired while idle
Changed /code-review so Claude can also start it on its own on Bedrock, Vertex AI, and Foundry, through the Claude apps gateway, and when telemetry or non-essential traffic is disabled
/goal: Changed idle sessions to start at most three check-ins on long-running background work per goal; your next message allows three more
Changed claude install and claude update to defer a pending managed-settings consent prompt to the next interactive session instead of prompting mid-command
Changed OpenTelemetry plugin events for plugins synced from claude.ai: plugin_id_hash now reflects the plugin's real marketplace, and enabled_via is admin-install for admin-installed plugins
Fixed the command sandbox's filesystem configuration not respecting --setting-sources

v2.1.239 Aug 21, 2026

v2.1.239

What's changed

Cost estimates (/cost, status line, --max-budget-usd) now include the 1.1× US-only-inference premium for data-residency workspaces
Added the one-time fullscreen renderer offer on Bedrock, Vertex, Foundry and other previously excluded setups; new installs there now start in fullscreen
Added /claude-api upgrade to migrate Python projects from anthropic 0.x to 1.x, and updated the skill's Python reference for 1.x (timeouts use anthropic.Timeout, not httpx.Timeout)
Cloud sessions: plugins synced from claude.ai now show as name@synced, work with claude plugin enable/disable <name>@synced, and never override a same-named plugin you installed
Alpine/musl builds: native image paste, clipboard, and audio-capture add-ons now load (musl-built binaries instead of glibc ones refused by the runtime)
The usage-limit message shown when your monthly spend limit is already used up now also says when your session or weekly limit resets
Fixed Bedrock streaming behind proxies that strip the response Content-Type header, which silently doubled billed API calls by re-running every turn non-streaming
Fixed Claude Code hanging at startup behind an HTTPS proxy when using Bedrock with an SSO profile and awsAuthRefresh — the credential pre-check now honors HTTPS_PROXY
Fixed a raw crash dump when starting Claude Code from a directory that no longer exists; it now prints a clear message
Fixed Edit and Write calls pausing for about 5 seconds in JetBrains IDE terminals when the Claude Code plugin is connected
Fixed a race where pressing Esc with a prompt queued could let the next turn finish early, leaving the session idle while Claude was still working and letting a later resubmit repeat actions
Fixed WebFetch retaining expired page content in memory for the whole session instead of the intended 15 minutes
Fixed cloud sessions (Claude Code on the web, desktop and mobile apps) resuming out of plan mode after an idle worker restart
Fixed MCP elicitation forms taller than the terminal being clipped in fullscreen mode: the form now fits the window, with hidden fields reachable by scrolling and Accept/Decline always visible
Fixed remote MCP servers staying failed after a transient 5xx on a mid-session reconnect in cloud sessions or via SDK setMcpServers()
Fixed custom session titles disappearing from /resume after more than ~64 KB of conversation was written following the rename
Fixed claude -c/resume picking up sessions from a different directory whose path differed only by characters like _, -, or .
Fixed /resume and the agents view showing a session as recently changed (and reordering it) when only its file was touched or it was merely reopened
Fixed /resume in all-projects mode telling you to cd into a deleted directory (e.g. a removed worktree); such sessions now resume in the current directory
Fixed the dark-ansi theme rendering expanded tool results in fullscreen mode with text the same color as the background
Fixed the fullscreen renderer prompt reappearing on every launch when it could never be answered; it now stops after being shown on three launches
Fixed .worktreeinclude patterns starting with **/ silently matching nothing when the target lived in a gitignored directory
Fixed agents, skills, and commands whose .md file starts with a UTF-8 BOM being silently ignored
Fixed /insights echoing literal <message> tags in its response on some models
Fixed marketplace metadata.pluginRoot having no effect: bare plugin source names now resolve under it as the docs describe
Fixed mouse movement in browser-based terminals inserting text like "35;150;7M" into the prompt when a mouse report arrived split across writes
Fixed custom theme overrides for the effort/ultracode status badge colors being ignored
Fixed OpenTelemetry trace fragmentation: tool executions deferred by a PreToolUse hook now resume in the original turn's trace instead of starting a new trace
Fixed vim mode in the agent view: Escape now switches to NORMAL mode and keeps your text instead of clearing the prompt
Fixed the selection:copy keybinding silently dropping a text selection that had been extended with Shift+Arrow keys
Fixed the /voice startup tip still appearing after voice dictation was enabled via the voice.enabled setting
Fixed shell-mode (!) Tab completion dropping the ./ from a ./script path, which left a command the shell couldn't run
Fixed fullscreen mode answering a permission prompt or pressing a button when you clicked the terminal window only to bring it back into focus
Fixed slash-command panels (e.g. /config, /model) in fullscreen mode covering the latest messages; the conversation now stays pinned above the panel
Fixed the /workflows detail dialog overflowing the terminal and losing its header off-screen when opened while Claude is still responding
Fixed the Linux sandbox making a nonexistent .git/config.worktree unreadable, which broke every sandboxed git command in repos with extensions.worktreeConfig set
Fixed hooks failing with "posix_spawn ENOENT" after the session's working directory was deleted; they now run from the project root or home directory instead
Fixed claudeMdExcludes not excluding a symlinked .claude/rules file when the pattern names the rules directory or the symlink rather than its target
Fixed runaway session-title syncing to Remote Control when two Claude Code processes shared one background job's state (2.1.232 regression); title updates are now deduplicated and rate-limited
Fixed sessions whose title starts with / being unaddressable by SendMessage and shown as "(untitled)" in ListAgents
Fixed Ctrl+W, Ctrl+U, Ctrl+K, Option+Backspace, Option+D and vim df/dt leaving a broken [Pasted text #N] placeholder when the cursor was inside it
Fixed masked (password-style) inputs such as the login code field letting their text be pasted back with Ctrl+Y elsewhere or saved to prompt history when cleared with double Esc
Fixed Ctrl+Backspace deleting one character instead of a word in search boxes
Fixed a request rejected by an organization policy check being re-sent before the rejection was shown
Improved the reminder shown after compaction so a skill's original arguments are not re-run as a new request
Long file paths on tool-use rows now truncate in the middle to stay on one line
Remote sessions keep sending keep-alives while a long SessionStart or Setup hook runs, so the container is not idle-reaped mid-hook
/goal: repeat check-ins on long-running background work now back off (30 min, then 1 h, then every 2 h) instead of repeating every 30 minutes
/goal: resuming a session from the claude --resume picker now restores its active goal
ListAgents now tells a session its own name (the one peers use to message it), and SendMessage to your own name says so instead of "no agent named …"
ListAgents and /list-agents now list your live teammates (previously only subagents and other sessions appeared, so a reachable teammate looked absent)
keybindingFlavor: "readline" now also matches Bash for word keys: Alt+F and Ctrl/Option+→ stop at the end of the word, Alt+D deletes to it (Ctrl+Y pastes it back), and punctuation separates words
Persistent retry mode (CLAUDE_CODE_RETRY_WATCHDOG) now fails immediately on organization spend-limit and out-of-credits errors instead of waiting indefinitely for a reset
Claude in Chrome: /clear now closes the session's Chrome tab group, and empty groups are closed on /resume and when Claude Code exits
Remote sessions: images uploaded from mobile now include their saved file path, so Claude can copy them into files it creates
Claude Code on the web: requests from Bash and other tools to non-API anthropic.com hosts (e.g. www, docs) now go through the session's network proxy, so your environment's allowed domains apply
Remote Control: clearer message and claude doctor wording when Remote Control isn't enabled for your account
Windows: cross-session messaging is now available, so Claude Code sessions across your machines can message each other with SendMessage and find each other with ListAgents, as on macOS and Linux
[VSCode] "View usage" in the usage-limit banner now sits inline with the warning text instead of floating mid-banner

●

v2.1.238 Aug 20, 2026

v2.1.238

What's changed

Added a keybindingFlavor setting: set it to "readline" to make Ctrl+W in the prompt delete back to the previous whitespace, as in Bash; the default ("classic") is unchanged
Plugin marketplaces: headersHelper on a url marketplace or a catalog entry runs a command that mints HTTP headers (e.g. a short-lived token) for catalog and same-origin archive fetches
A catalog entry's headersHelper runs only when you install or update that plugin, after its command is shown; claude plugin install/update ask [y/N] (or pass -y)
Added claude self-hosted-runner --defer-shutdown-max-min <minutes>: on SIGTERM, keep serving attached sessions, park what is left after that many minutes, then exit
Added claude self-hosted-runner --proxy-authorization-command / --proxy-authorization-file for egress proxies that require a freshly issued Proxy-Authorization header on every connection
Fixed unbounded memory growth in long interactive sessions: subagent tool results are now released once they leave the recent display window
Fixed custom, project, and plugin output styles drifting back to the default voice mid-session
Fixed CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION=true not keeping prompt suggestions on when your account is near, but not over, its usage limit
Fixed worktree-isolation Bash refusals telling you to remove a redirect when the command had none
Fixed self-hosted runners occasionally being removed by the server after a single slow or lost poll request, handing their healthy session to another runner
Fixed MCP elicitation dialogs showing nothing for URLs longer than 4,096 characters, and permission prompts dropping the "don't ask again" option when the project path didn't fit the terminal width
Fixed leftover /tmp/claude-*-cwd files when a Bash command is killed, times out, or is interrupted
Fixed held Backspace being ignored on terminals that send Ctrl+H for Backspace when keystrokes arrive in large bursts (slow SSH/mosh links)
Fixed text-wrapping in permission prompt diffs: lines containing wide multi-code-point characters (such as emoji) or tabs are no longer clipped
Fixed killing a suspended (Ctrl+Z) session sometimes leaving the terminal in bracketed-paste mode with the cursor hidden
Fixed stdio MCP servers receiving a server/discover request before initialize, forcing lazy servers to start their backend on every session open
Fixed a proxy's refusal of a connection being reported as a generic network error instead of naming the proxy
Fixed the /model and /effort cache-miss warning appearing when the prompt cache had already expired
Fixed per-task Stop from the Remote Control tasks panel doing nothing on CLI-hosted sessions
Fixed remote sessions exiting when a client delivered a user message without a valid role
Fixed Remote Control sessions started by claude remote-control inheriting session-scoped environment variables from the launching shell
Fixed a Remote Control session whose process crashed staying unavailable until claude remote-control was restarted; it can now be reused when you next message it
Fixed Remote Control messages sent from the web or Desktop while Claude is mid-turn disappearing from the transcript after the turn finishes
Fixed Remote Control model picks made on a phone or web not updating the model shown in the terminal
Fixed Remote Control disconnecting with "login expired" when a brief network hiccup delays renewing your sign-in; it now retries and stays connected
Fixed Remote Control reporting a failed reconnect on sign-out; signing out now ends the session with a clear message
Fixed ListAgents/SendMessage reporting "Remote Control is not connected" in sessions run by claude remote-control (server mode) or Desktop/IDE hosts; they now list and reach Remote Control peers
Fixed ListAgents and SendMessage exposing the idle worker that the agent view pre-warms for your next background session; it now appears only once a task claims it
Cross-session messaging: sending to a session on this machine that refuses inbound messages (e.g. crossSessionInbound: "refuse") now reports "refused" to the sender instead of a silent success
Cross-session messaging: a session whose inbox drops your messages (rate limit or full queue) now tells your session, instead of the messages vanishing silently
Improved startup: bare claude starts sooner on macOS
Improved Bash tool permission checking for zsh-specific syntax in shell conditionals
Improved Remote Control connection resilience: brief HTTP 403 refusals from a network edge, VPN, or proxy are now tolerated for up to 3 minutes, with the refusing party named when a block persists
Improved startup responsiveness: the automatic update check now runs about 10 seconds after launch instead of competing with startup for CPU
Updated the bundled claude-api skill for the Managed Agents Aug 19 release: web search/fetch domain settings and memory stores on self-hosted sandboxes
Changed Ctrl+L and Cmd+K in fullscreen to always just repaint — the double-press /clear shortcut was removed, and 1-row nvim terminals no longer trigger automatic /clear loops
Changed claude mcp list and claude mcp get to show disabled servers as ⊘ Disabled instead of connecting to them for a health check
MCP headersHelper in a project .mcp.json, and inline MCP servers in project or --add-dir agent files, now require that folder's trust dialog to have been accepted (also under claude -p)
MCP headersHelper from a project .mcp.json, plugin, or agent file runs without inherited credential env vars; user, managed and claude.ai-scope helpers now run from the Claude config dir

v2.1.237 Aug 20, 2026

v2.1.237

What's changed

Fixed prompt caching for sessions using an LLM gateway or custom base URL
Added a built-in "Concise" output style: Claude leads with results and skips preamble and narration, while doing the work just as thoroughly. Select it under Output style in /config.

⚡

v2.1.236 Aug 19, 2026 Breaking

v2.1.236

What's changed

Added ANTHROPIC_DEFAULT_MODEL environment variable: sets the model new sessions start on, while a /model pick still overrides it and persists across restarts (unlike ANTHROPIC_MODEL)
Added notify_when_idle to cross-session SendMessage: ask another Claude Code session on this machine to send one notice when it next goes idle — opt-in, one-shot, no polling (macOS and Linux)
Sandbox: on macOS, wildcard read-deny rules (e.g. **/.env) now take precedence inside allowed read regions, cover matched directories' contents, and can't be bypassed by renaming the denied file
Fixed clipboard copy, background housekeeping, background sessions, and local MCP logs breaking after the directory a session had switched into was removed (since 2.1.229)
Fixed the fullscreen renderer failing permanently after a single failed start: it now falls back to the classic renderer instead of exiting on every subsequent launch
Fixed the /model picker rendering taller than the terminal: it now shows only as many models as fit the window, with the rest reachable by scrolling
Fixed SendMessage calls being rejected when a malformed closing tag left the message text inside the summary field
Fixed unhandled promise rejections when a subprocess fails to start, for example powershell.exe on WSL with Windows interop disabled (regression in 2.1.234)
Fixed fullscreen mode sometimes not showing a newly sent message until the next update after the terminal was resized
Fixed a blank band that could remain above the prompt after clearing a multi-line prompt, and panes not repainting after resizing the terminal away and back, in fullscreen mode
Fixed the managed-settings approval prompt sometimes not appearing at startup while still capturing the first keypress as approval
Fixed terminal tab titles jumping in tmux (iTerm tmux integration): the title is now written only when its text changes instead of animating every 960ms
Fixed an unclear error when the cloud environments list came back empty or malformed
Fixed the Fable 5 first-time usage-credits prompt auto-selecting the fallback model after 60 seconds with no answer when using Remote Control
Fixed spinner tips never appearing, with a repeated background error, when the cached guest-pass reward in ~/.claude.json was malformed
Fixed skills hot-reload in SDK/VS Code sessions raising an error on every skills change after the session's working directory was deleted (2.1.229+)
Fixed self-hosted runner sessions released on idle, retire, or startup timeout occasionally resuming on another runner before the post-session hook had finished
Fixed the Clawd mascot's eyes and feet rendering unevenly in iTerm2 at some font sizes
Fixed occasional runaway session recaps: recap text (automatic and /recap) is now capped at 400 characters, cut at a word boundary
Improved startup performance: the session counter is now written in the background
Improved auto mode: Monitor allow rules are now set aside while auto mode is active, so Monitor commands are reviewed the same way Bash commands are
Improved auto mode on Bedrock, Vertex AI, and Foundry, and when telemetry is disabled: the classifier now uses the same defaults as on the Claude API, including severity-scored classification
Improved auto mode: the git status check can no longer be fooled by a repo's status.showUntrackedFiles=no setting into reporting a clean tree
Changed the /model picker to highlight only the newest model's name, so the highlight marks the new release rather than an arbitrary subset of the list
/goal: an idle session whose goal is parked behind long-running background work now checks in automatically after 30 minutes (then 1h, 2h) instead of waiting for you to return
/usage now shows the usage-credits spend row for Team and Enterprise members, and shows a capped row at 0% before anything is spent
SIGTERM in print/SDK mode no longer records an interrupted turn or synthetic tool denials before exiting; running commands are still terminated and the process still exits with code 143
Pressing Enter on a slash-command typo or a command unavailable in this session now reports it instead of running the closest fuzzy match; prefixes and aliases still run
Remote Control now marks a session offline within seconds when the CLI exits or its terminal closes
SendMessage now refuses further messages to a session up front once a rapid burst would exceed what that session's inbox accepts, instead of reporting them sent while they were dropped
Aligned the session title chip on the prompt border with the footer's right edge
Right-aligned footer items (goal indicator, session state, background agent status) and truncated notices now share a consistent right margin with the rest of the prompt area
[VSCode] Added screen reader support for the transcript: live announcements for replies, permission requests, errors, and status changes, plus per-turn heading navigation

●

v2.1.235 Aug 18, 2026

v2.1.235

What's changed

Added an optional spellcheck setting that underlines misspelled words in the prompt input as you type, using your installed aspell, hunspell, or ispell
Fixed whole-prompt-cache invalidation when a language server disconnected or reconnected mid-session
Fixed nested markdown list items misaligning at depth 3+ and added a hanging indent to wrapped list items in the terminal UI
Fixed prompt input highlights (slash commands, keywords, mentions) appearing shifted by one or more characters in some multi-line prompts
Fixed Shift+Tab inside the permission prompt's comment field approving the edit and granting session-wide edit permission instead of closing the field
Fixed the Agent tool advertising a general-purpose default in sessions where that agent is unavailable: an omitted subagent_type there now gets a clear error listing the available agents
Fixed notebook cell delete/replace approval dialogs silently omitting the existing cell content when the notebook or cell could not be read; the dialog now says why
Fixed slash commands run while Claude is responding showing HTML entities instead of the actual characters
Fixed the prompt footer not showing the "Update installed" restart notice after a background auto-update
Fixed the expanded task list (ctrl+t) always starting collapsed when resuming or relaunching into a session that still has open tasks
Improved memory and CPU usage while cloud sessions such as /ultrareview or /autofix-pr run in the background — their event streams are no longer re-scanned and re-rendered on every update
Improved permission dialogs: display text and "don't ask again" options now always match what a grant would cover, and "don't ask again" is withheld when contents cannot be fully displayed
Improved the embedded grep in native macOS/Linux builds: pathological patterns now fail fast instead of exhausting memory, and -m N with -A/-C prints correct context
Improved the context-limit error to say when auto-compact is off and point to /config to re-enable it
Vim mode: NORMAL mode and cursor position are now preserved when toggling the detailed transcript (ctrl+o) or closing a panel
Dialogs: arrow keys and Enter pressed in quick succession now select the option you navigated to instead of the previously highlighted one
SendMessage now refuses messages too large for cross-session delivery up front instead of silently dropping them
Remote Control: claude rc now applies the same enterprise-gateway availability check as interactive startup
[VSCode] Fixed focus jumping between open Claude tabs on its own when a window with several Claude panels is restored or reloaded

●

v2.1.234 Aug 17, 2026

v2.1.234

What's changed

Added the optional CLAUDE_CODE_PROJECT_DIR_NAME environment variable: hosts that give each session its own config directory can choose a short name for the per-project transcript directory
Added the selection:clear keybinding action, so a key can be bound to clear an in-app text selection; also works in the agents view
Added a GitLab merge request badge to the footer and statusline: repos with a GitLab remote and an authenticated glab CLI show MR !N with draft/pending/green states
Claude Code now continues your session automatically when a claude.ai usage limit resets; turn it off in /config ("Continue automatically at usage limit")
Claude is now told to use your account email only to identify you, and not to send it to unrelated services unless you ask
Security: remote file reads, session restore, CLAUDE.md includes, workflow scripts and file uploads now reject Windows NT-namespace (\??\) paths, hardening the remaining pre-approval file accesses against the NTLM credential-leak vector
Fixed auto mode in very long sessions repeatedly re-checking and denying sandboxed commands' network access after the conversation had been compacted
Fixed session-scoped permission answers (including denies) being dropped when answering background subagent tool permission prompts
Fixed a crash when an API response on the non-streaming fallback path (typically via third-party gateways) contained a thinking block missing its thinking field or a text block missing its text field
Fixed markdown rendering becoming extremely slow for some messages containing unusual Unicode sequences
Fixed SendMessage rejecting a recipient copied from ListAgents when the session name is at the 200-character cap or emoji-heavy
Fixed repository detection mis-reading the host of git remotes with unusual userinfo, producing links and repo-specific behavior for the wrong host
Fixed MCP diagnostics printing resolved secrets: scope-conflict warnings now show the configured ${VAR} form, and connection-failure details show only the server origin
Fixed strictKnownMarketplaces allowlists accepting SCP-style git marketplace sources whose host differs from the one git would actually connect to
Fixed modal text such as the /login OAuth URL losing characters when copied in fullscreen
Fixed a --- horizontal rule in rendered markdown running into the line after it
Fixed consecutive shell commands splitting into multiple "Ran 1 shell command" rows when todo/task updates were interleaved between them
Fixed dialogs like /permissions opened while a ! shell command was running being dismissed when the command finished
Fixed a queued ! shell command being sent to the model as plain text after pressing up-arrow to edit the queued input
Fixed queued messages reappearing in the prompt history while still queued, Esc while selecting a queued message no longer interrupts the turn, and ! mode no longer sticks after a mid-turn submit
Fixed accepting the "Try the new fullscreen renderer?" prompt restarting the session without its permission mode (e.g. --dangerously-skip-permissions), tool allow/deny rules, model or effort flags
Fixed /tui dropping launch --allowed-tools/--disallowed-tools rules when it restarts; it now declines to switch, with the reason, when the session has restrictions a restart can't carry over
Fixed trust prompts omitting the repository-wide scope warning when the directory was first seen before the repository existed there
Fixed a case where an IDE diff tab closing during a permission re-prompt could answer the new prompt with the previous input
Fixed: files sent to the user during Remote Control sessions hosted by Claude Code Desktop or VS Code now upload, so they open on phone and web instead of showing an empty card
Fixed: after /login while CLAUDE_CODE_OAUTH_TOKEN is set, the stale-token reminder no longer leaks into Claude's automatically resumed turn — it now appears only to you
Fixed: permission previews now relay only to channel servers admitted by the inbound trust gate, and a server's explicit permission-capability opt-out is honored
Fixed: credential masking on relayed permission previews can no longer hide commands, paths, or destinations from the approver; oversized private-key blocks now redact under full-strength redaction
Fixed: provider API tokens that mask on permission previews now mask even when directly followed by shell delimiters
Fixed Claude Desktop inter-session messages being silently dropped by the recipient session when cross-session messaging read as disabled, which left the sender's query "thinking" for many minutes
Remote Control: signing this computer in to a different claude.ai account or organization now stops the running session within seconds and says why, instead of a misleading HTTP 404 hours later
Remote Control sessions started from Claude Code Desktop or VS Code now keep phones and claude.ai/code updated on the session's permission mode (and claude.ai/code on the model) as they change
Remote Control: effort picks made on a phone or on claude.ai/code now apply to terminal- and Desktop/VS Code-hosted sessions, and the session publishes its effort level to connected clients
SendMessage and ListAgents now say when your account's session list was too long to check completely, instead of treating unseen sessions as absent
Expired Anthropic profile credential now points you at /login when a claude.ai login would take precedence
Improved the transcript: your own prompts now render markdown (highlighted code blocks, inline code, lists) the same way replies do
Improved the "API returned an empty or malformed response" error to say what came back (content type, body kind, size, request ID) and why the original streaming request failed
Improved auto-generated session titles to read as short, specific names (e.g. "Login button bug") rather than sentences restating your request (e.g. "Fix the login button on mobile")
Reduced the context cost of loading the built-in claude-api skill from ~200k+ tokens to ~25k by loading reference docs on demand
/permissions can now be opened while Claude is working — rule changes apply to the rest of the current turn
/add-dir <path> can now be used while Claude is working; /add-dir, /autocompact, /theme, /help, /config and /advisor dialogs open mid-turn in the fullscreen TUI
/goal now clears itself with a notice when a turn dies on an unrecoverable error (e.g. revoked auth, an exhausted credit balance, or a context overflow) instead of staying armed
/goal: when background tasks keep a goal waiting for 30+ minutes, Claude now checks in on them instead of waiting indefinitely (set CLAUDE_CODE_GOAL_CHECKIN_MINUTES=0 to opt out)
claude setup-token now rejects unexpected extra arguments instead of silently ignoring them
Changed Esc in fullscreen mode to no longer clear a mouse text selection: it interrupts or dismisses as usual and the selection stays highlighted
Removed the redundant "Allowed by auto mode classifier" line that auto mode showed under every Agent tool call
Removed the "Default teammate model" setting from /config; agent-team teammates now use the leader's model unless the spawn names one
Dimmed the elapsed-time counter on the running tool header so it no longer competes with the bold counts
Background task notifications delivered between turns are now sent to the model inside <system-reminder> tags, matching mid-turn delivery
Mantle: skip the admin-pin availability probe at startup when a main-loop model is already picked
Windows: startup no longer stalls on repeated rename retries when ~/.claude.json is read-only

v2.1.233 Aug 14, 2026

v2.1.233

What's changed

Added GitLab merge request URL support to the --worktree flag and the claude agents view (where MRs display as !N)
Added an opt-in forward_user_identity apps gateway setting on Anthropic upstreams that sends the signed-in user's identity as headers, so a proxy behind the gateway can attribute spend per user
Added opt-in memory cgroup support for Bash tool commands on Linux (CLAUDE_CODE_TOOL_MEMORY_LIMIT) so a runaway build can't stall the session
Added CLAUDE_CODE_WEBFETCH_CACHE_TTL_MS environment variable to configure the WebFetch session URL cache TTL (default unchanged: 15 minutes)
Fixed cloud sessions occasionally being marked as lost when the environment shut down while Claude was waiting on a permission prompt
Fixed MCP v2 connections endlessly reopening the subscriptions/listen stream against servers that terminate long-held streams on a fixed timeout (e.g. serverless hosts)
Fixed Notification hooks not firing for permission prompts when running under Claude Desktop or VS Code
Fixed idle sessions on Linux sometimes keeping one CPU core at 100% when sandboxing is enabled
Fixed bundled skill aliases like /checkup and /review reporting "Unknown command" in -p mode or with plugins/MCP loaded when a user or project skill shadows the bundled skill
Fixed skill/command argument substitution to prevent argument values from being re-expanded as template markers
Fixed Windows paths spelled with the NT \??\ device prefix bypassing UNC path validation, closing an NTLM credential-leak vector
Improved claude self-hosted-runner session start time: the session branch is now created without rewriting the working tree, and two server round trips no longer block the agent's launch
Improved apps gateway error forwarding: 400/413 errors from Vertex, Foundry, and Claude Platform on AWS upstreams now carry the upstream's own message; fixes a bug with auto-compact on apps gateway
Improved claude plugin validate to check a bare .claude/skills directory, reporting SKILL.md files whose frontmatter fails to parse
Improved screen reader mode: the /effort selector renders as a numbered list with a typed-number prompt, and hint and dialog text is no longer clipped
Improved print mode diagnostics: a [claude-code:unrecognized_model] line is written to stderr when a request goes out for a model ID Claude Code doesn't recognize; map it with modelOverrides to silence
Changed the GitHub app setup tip to no longer appear in repositories whose origin remote is on gitlab.com or bitbucket.org; the enterprise marketplace tip now covers non-GitHub internal git hosts
Todo/task-tracking tools (TaskCreate/Get/Update/List, TodoWrite) are no longer available on Opus 4.8, Sonnet 5, Fable 5, Mythos 5, and newer models; set CLAUDE_CODE_ENABLE_TODO_TOOLS=1 to bring them back
Windows: fixed auto mode repeatedly stopping for manual approval on ordinary cd <dir> && <command> > file Bash commands (a 2.1.232 regression)
Reverted the 2.1.232 Bash permission changes for Cygwin-style symlinks on Windows and for input redirections (< file); a narrower version will return in a later release
