9<Update label="2.1.296" description="October 9, 2026">
10 **Added**
11
12 * Added a `code` key to the Claude apps gateway's `managed.policies[]`: the same settings as `cli`, also applied in Claude Desktop's Code tab; beside `desktop`, it turns on Claude Desktop's gateway mode
13 * Added `autoCompactWindow` to subagent frontmatter and `--agents` definitions, so a subagent can auto-compact earlier than the main conversation's window
14 * Added `CLAUDE_CODE_WORKFLOW_SUBAGENT_MODEL` to run every workflow agent on one model while other subagents keep theirs
15 * Added `CLAUDE_CODE_OVERLOADED_RETRY_MAX_DELAY_MS` environment variable to set a longer maximum delay for the backoff when retrying an overloaded (529) request
16 * Added a note in `/plugin` on a plugin whose hooks are left out because another enabled plugin has the same name
17 * Added an `allow_large` option to the Read tool so Claude can read a text file past the usual size limits in one call when it needs the whole file and the context has room
18 * \[Cloud sessions] Added a status filter to the Sessions and Runners lists on a self-hosted environment's Activity tab in admin settings; you can pick several statuses at once
19 * \[Claude Tag] Added creating, editing and deleting workspace and channel memory files on the Activity page's Memory tab for members with the Claude Tag Admin permission
20
21 **Changed**
22
23 * Updated `/cost`, the status line, `--max-budget-usd` and the SDK's cost figures to price Sonnet 5.5 cache reads at $0.10 per million tokens (was $0.20)
24 * Updated the bundled dataviz skill: lighter violet for the seventh series in light mode, softer primary text in dark mode, and compact y-axis labels like 1K
25 * Changed the default limit on MCP tool descriptions sent up front and on MCP server instructions from 2,048 to 4,096 characters
26 * Changed `←`: a turn or `!` command started while the session moves to the background is now stopped instead of finishing out of sight
27 * \[VSCode] Changed Claude in Chrome to ask before browser actions in every session, including one connected with `@browser`, as the terminal does; allowing a site for the session stops repeat asks
28 * \[Claude Tag] Changed Claude in Slack to show the footer with the session link, model and cost only on its newest reply in a thread; the reply before it drops the footer
29
30 <Expandable title="9 improvements">
31 - Improved fullscreen mode: the link under the mouse pointer is now underlined to show it can be opened
32 - Improved transcript toggle (ctrl+o) responsiveness in code-heavy conversations by caching syntax-highlighted code blocks
33 - Improved Claude Desktop's Code tab behind a Claude apps gateway: when a session can't start, including on a machine not set up for the gateway's `code` settings, the reason shows as a reply
34 - Improved the errors for a refused cloud session: they now say why your organization's policy couldn't be loaded, and name an API key or auth token that overrides your claude.ai login
35 - Improved `--debug` output to name unrecognized frontmatter fields in custom agent files, with a hint for likely typos
36 - Improved auto mode: a tool call that wasn't run because auto mode's check had no usable answer now shows as a dim "Not run" row instead of a red error
37 - Improved `--debug` output for hooks: command hooks on tool calls, prompts, SessionStart and Stop now log their command, plugin, outcome and duration when they finish, so a slow hook is identifiable
38 - Improved `CLAUDE_CODE_TRANSCRIPT_LOCAL_GC`: a large transcript file is no longer rewritten when that would free under 10% of it
39 - \[Code Review] Improved Code Review admin settings to say why a setting couldn't be saved, such as a policy restriction, instead of a generic failure message

42 <Expandable title="56 bug fixes">
43 * Fixed managed-settings `PreToolUse` hooks that deny a tool call with `"continue": false`, and managed `prompt` hooks that block one, refusing the call but not ending the turn
44 * Fixed PostToolUse hooks in managed settings not applying `updatedMCPToolOutput` in some sessions
45 * Fixed headless sessions starting a folder's `.mcp.json` or plugin MCP server that was switched off for that folder, after changing directory or reloading plugins
46 * Fixed a Claude apps gateway that serves `allowedProviders` with `"gateway"` locking out laptops that name that gateway in user settings
47 * Fixed a saved Claude apps gateway sign-in being ignored on machines whose managed settings set `forceLoginMethod` to `gateway` with no `forceLoginGatewayUrl` (regression in 2.1.295)
48 * Fixed `--teleport` opening an empty conversation when the session's history could not be read
49 * Fixed token counts for Haiku 5.5 and other models that take only adaptive thinking, which failed behind some gateways and were counted with budget thinking elsewhere
50 * Fixed resumed subagents being told that the user rejected a tool call that a session shutdown had interrupted
51 * Fixed hook output being altered when it contained text resembling a plugin hint tag
52 * Fixed secret redaction in shared transcripts and debug logs missing some values that follow a key with no value, including in JSON written inside a shell string
53 * Fixed a stray `52;c;…` escape sequence printed on screen after copying in older VTE-based terminals such as MATE Terminal
54 * Fixed toasts and notifications waiting unseen for as long as the `/diff` panel or dialog was open
55 * Fixed Esc or an interrupt during a `UserPromptSubmit` hook or a mod's `prompt.submit` hook ending headless sessions, clearing the typed prompt, or letting the unchecked prompt through
56 * Fixed SessionStart hooks of a plugin loaded after a headless session starts being skipped when a different plugin with the same name, or another spelling of it, had already run
57 * Fixed `claude self-hosted-runner` printing misleading errors when registration is refused: it now names the org admin setting, or says a restarted on-demand runner needs a fresh work order
58 * Fixed a self-hosted runner session's git fetch, pull and push failing while another session of the same repository starts on a runner with `--capacity` above 1
59 * Fixed workflow scripts silently truncating results, agent options and other values nested deeper than about 20,000 levels, and deeply nested results writing huge task output files
60 * Fixed a plugin's served `$` methods running in the main session's working directory instead of the calling agent's, and ignoring the turn their calling hook holds
61 * Fixed `$.agent.register` succeeding from a mod's hook that was still running after the mod was reloaded or removed; the call is now refused
62 * Fixed `$.http.fetch` in mods refusing a `HEAD` request when the response declares a `Content-Length` over the 4 MiB body limit
63 * Fixed `claude plugin marketplace add`, `marketplace update` and `plugin install` failing with an internal error for a marketplace named like `constructor`; `add` now refuses such names clearly
64 * Fixed a plugin secret named `constructor` or `prototype` being deleted by the next save of that plugin's options
65 * Fixed cloud sessions skipping auto mode's checks on Claude in Chrome actions that a saved permission allows when their feature flags had not loaded
66 * Fixed `CLAUDE_CODE_RESUME_INTERRUPTED_TURN` re-running a finished turn after a restart when an MCP tool result had ended that turn
67 * Fixed Bash permission checks auto-approving some commands that assign the `BASH_ARGV0` shell variable and then use it; these now prompt for approval
68 * Fixed Edit and NotebookEdit replacing every non-ASCII character in files that are not valid UTF-8 (Windows-1252, Shift-JIS, GBK); such edits are now refused
69 * Fixed a prompt sent just after `←` being run twice, once unseen in the foreground, when the background service was slow to answer
70 * Fixed a prompt sent while SessionStart hooks were still running vanishing when `←` moved the session to the background; it is still not sent, but `↑` now brings it back
71 * Fixed a late-loading plugin's SessionStart hook output reaching the new conversation after `/clear` in headless sessions
72 * Fixed PowerShell commands not seeing variables that hooks write to CLAUDE\_ENV\_FILE (when the file holds only plain assignments)
73 * Fixed Claude calling cloud sessions non-interactive and suggesting `/mcp` or `claude mcp` when an MCP server needs authentication
74 * Fixed `/code-review` ending on a raw JSON array in cloud sessions, the Agent SDK and IDE integrations; the findings now print as a numbered list
75 * Fixed auto mode occasionally refusing one update to your own artifact, saying its sharing had changed when it had not
76 * Fixed skills synced from claude.ai never finishing their install, and being downloaded again at every sync, when several sessions share a config directory
77 * Fixed a plugin synced from claude.ai being disabled when the marketplace dependency it declares was also synced from claude.ai
78 * Fixed a startup hang on macOS when plugin paths copied from a Linux machine pointed under /home
79 * Fixed the Workflow tool refusing script files with CRLF line endings, such as files checked out on Windows
80 * Fixed OpenTelemetry `tool_result` events missing `git_commit_id` after `git commit -q` or `git -C <dir> commit`
81 * Fixed `CLAUDE_CODE_TRANSCRIPT_LOCAL_GC` dropping a message from the saved transcript when its text held a Unicode line or paragraph separator (U+2028, U+2029)
82 * Fixed `claude purge` leaving a prompt in the history file when its text held a Unicode line or paragraph separator (U+2028, U+2029)
83 * Windows: Fixed PowerShell commands longer than about 1 KB always asking for permission, so allow rules and read-only detection now apply up to 32 KB
84 * Windows: Fixed stdio MCP servers being force-killed at shutdown; stdin now closes first and the process tree is killed only if the server is still running after 300 ms
85 * Windows: Fixed `claude plugin install` failing for GitHub `owner/repo` plugin sources on machines with no GitHub SSH key; the clone is now retried over HTTPS
86 * Windows: Fixed `rm -rf /c/Users/<name>` in Git Bash not asking in bypass permissions mode
87 * \[VSCode] Fixed `claudeCode.spinnerVerbs` missing from the extension's settings, so settings.json now completes and validates it; a malformed value no longer breaks the chat panel
88 * \[VSCode] Fixed chat links written as a full Windows path, such as C:\repo\file.ts or file:///C:/repo/file.ts, not opening the file on Windows
89 * \[VSCode] Fixed the working indicator still animating when reduced motion is turned on in your OS, in VS Code, or with the `prefersReducedMotion` setting
90 * \[VSCode] Fixed the prompt cache clock reading warm after the panel caught up on messages late, such as after the display was off or a remote window reconnected
91 * \[Cloud sessions] Fixed every cloud session waiting for a self-hosted runner showing the same queue position; each now shows how many sessions are ahead of it
92 * \[Cloud sessions] Fixed a message you send while Claude is still replying in a cloud session jumping above that reply when it finishes; it now stays below it, including after a reload
93 * \[Claude Tag] Fixed links to URLs that contain parentheses breaking in some of Claude's Slack replies and task checklists, which showed stray bracket text and opened the wrong page
94 * \[Claude Tag] Fixed Claude's Slack replies drawing color swatches beside codes that only look like hex colors, such as six-digit pull request numbers
95 * \[Claude Tag] Fixed the plugin confirmation card Claude posts in a Slack channel showing a plugin's ID instead of its name
96 * \[Claude Tag] Fixed Claude in Slack posting a card to remove a plugin the channel's own settings don't include; it now explains where the plugin comes from instead
97 * \[Claude Tag] Fixed Claude in Slack sometimes losing its reply when a session in a self-hosted environment moved to a new runner partway through a task
98 * \[Code Review] Fixed the Code Review check sometimes staying "in progress" on a pull request after the review finished; it now shows the review's result

from line 1894
18011894 * Fixed a `sandbox.excludedCommands` glob exempting an entire compound Bash command from the sandbox when only one part matched; every part must now match
18021895 * Fixed resumed subagents and teammates re-rendering the MCP tool definitions they had loaded, which broke prompt caching for that agent
18031896 * Fixed rate-limited artifact publishes telling Claude to stop retrying; Claude is now told nothing was published and when to send the same publish again
1804 * Fixed attachments recorded earlier in a conversation being re-rendered after a resume or relaunch, which dropped extended thinking and missed the prompt cache
1805 * Fixed Console sign-in showing only "Request failed with status code 400" when the server refuses to create an API key; it now shows the server's message
1806 * Fixed messages typed while Claude is still working sometimes being ignored by the model
1807 * \[VSCode] Fixed the "General config" menu row showing `/config` usage text instead of opening settings, and made typed `/mcp`, `/hooks`, `/memory`, `/rewind` and similar commands open their dialogs
1808 * \[VSCode] Fixed the effort slider's level not persisting into later sessions on a model that already had a level saved with `/effort`
1809 * \[VSCode] Fixed Auto missing from the mode picker for conversations opened in an already-used panel when the saved model setting is a differently-cased alias such as "Sonnet"
1810 * \[VSCode] Fixed `/fast` not saving fast mode as the default, so it was lost when the extension relaunched Claude Code
1811 * \[Claude Code on the web] Fixed a cloud environment saved with Custom network access and no domains silently reverting to Trusted; the dialog now asks for at least one domain
1812 * \[Claude Tag] Fixed routines created in a Slack channel on an Enterprise Grid org-wide install failing to read other public channels in their workspace when they ran
1813 * \[Claude Tag] Fixed the "Learn more" links on credential presets in Claude Tag access bundles to open each vendor's credential-setup page instead of a generic API reference
1814 * \[Claude Tag] Fixed Google Cloud credential forms in Claude Tag access bundles: a refused key file now says why, the website and scopes stay locked, and a rejected rotation keeps the pasted key
1815 * \[Claude Tag] Fixed the network events log in Claude Tag admin settings showing no response status for requests through connections that use AWS signing, client certificates or a custom CA

1819<Update label="2.1.276" description="September 18, 2026">
1820 * Fixed every request failing with `400 … Input tag 'advisor_20260301'` when `ANTHROPIC_BASE_URL` points at a proxy or gateway (2.1.275 regression)
1821</Update>
1822
1823<Update label="2.1.275" description="September 17, 2026">
1824 **Added**
1825
1826 * Added the signed-in account to Claude apps gateway sign-in: when the gateway names it, you confirm it before the credential is saved, and `/status` shows it
1827 * Added a send-now key (ctrl+enter, or ctrl+x ctrl+s) that interrupts the current turn and sends all queued messages at once; sent and queued messages show in gray until the model receives them
1828 * Added a startup warning when a configured `otelHeadersHelper` fails, so sessions that silently export no telemetry are noticed
1829 * Added syncing of the skills and plugins enabled on your claude.ai account to terminal sessions signed in with it; opt out with `syncClaudeAiSkills: false` or `syncClaudeAiPlugins: false`
1830 * Added `/plugin install <plugin> --marketplace <source>`, which offers to add the marketplace before installing the plugin
1831 * \[VSCode] Added viewing, editing and deleting a saved memory inside the Memory dialog
1832 * \[VSCode] Added sending an attached image without typing any text
1833 * \[VSCode] Added a Retry link to the MCP servers dialog when the server list fails to load
1834 * \[VSCode] Added accept and reject buttons under each change in the proposed-change diff tab, so an edit can be reviewed change by change
1835 * \[Claude Code on the web] Added a "New routine" button to the page shown when a routine link no longer resolves, next to the link back to your routines list
1836 * \[Claude Tag] Added attach conditions for access bundles in Claude Tag settings: an Owner can let a bundle also apply in channels with guests or Slack Connect channels, not just member-only
1837 * \[Claude Tag] Added Amazon CloudWatch, CloudWatch Logs, Amazon SNS, Google Cloud Monitoring and Cloud Logging presets to an access bundle's Credentials tab in Claude Tag admin settings
1838 * \[Claude Tag] Added Datadog presets for the US3, AP1, AP2 and US1-FED sites; new Datadog connections are now limited to Datadog's read and query API routes
1839
1840 **Changed**
1841
1842 * Updated `/logout` for Claude apps gateway sign-ins to also end the session on gateways that advertise token revocation
1843 * Changed hosted sessions to keep an unanswered permission prompt up after a container restart, instead of asking again
1844 * Changed the Artifact tool to ask for a one-word tab icon on a first publish instead of an emoji favicon
1845 * Changed Claude in Chrome in auto mode to skip the extension's per-site check for classifier-approved calls, as bypass mode does, fixing `browser_batch` "Permission denied" after a redirect
1846 * Changed plugins installed from an npm source to be fetched with `npm pack --ignore-scripts` and integrity-verified, so a package's install scripts no longer run
1847 * Changed scheduled and Run now routine runs to save data to, and republish the page of, an artifact you can edit without asking; public artifacts, first publishes and deletes still ask
1848 * Removed the startup notice that told you a one-off scheduled routine had run since your last session
1849 * \[VSCode] Changed New session in a Claude editor tab to open in the sidebar when Preferred Location is set to Sidebar, instead of always opening another tab
1850 * \[VSCode] Changed a message sent while Claude is working to wait at the bottom of the conversation until Claude starts on it
1851
1852 <Expandable title="13 improvements">
1853 - Improved prompt caching for a `--system-prompt` that contains a `__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__` line: the text above it is now cached globally, as the SDK's array form already is
1854 - Improved the `/desktop` error when Claude Desktop does not open: it now says why and what to do next
1855 - Improved the Artifact tool's publish and read results: they now say who can open the page and what the owner's Share menu offers
1856 - Improved artifact publish results: they name the tab icon sent, warn when the page contains a NUL byte, and retry a flaky fetch of the newer page to merge after a stale publish
1857 - Improved pasted and attached images: they are now saved where Claude can open them as files without a permission prompt, including in Desktop and VS Code
1858 - Improved the Artifact tool's guidance so Claude updates a shared artifact in place when you were given edit access to it, instead of publishing a separate copy
1859 - Improved plan-usage reads: editor windows and non-interactive sessions on one machine now share a read made in the last minute instead of each calling the usage endpoint
1860 - Improved the `ListPlugins` tool description so Claude knows it lists plugins enabled on your claude.ai account, not plugins installed locally with `/plugin`
1861 - Improved responsiveness when the terminal is slow or paused: output no longer falls further behind while the terminal catches up
1862 - Improved Write and Edit results for files in the synced account-skills folder: they now say the change is not saved to your account and how to save it
1863 - \[VSCode] Improved the agent map: the pill counts running agents and turns red after a failure, the main agent stays in view while the map scrolls, and agents sort by state then end time
1864 - \[Claude Code on the web] Improved what Claude tells you when asked to edit, delete or run a routine it didn't create: it now links to the routine's page so you can do it yourself
1865 - \[Claude Tag] Improved Claude's notices in Enterprise Grid channels shared across workspaces: they now say when no workspace is set up yet, or why only organization defaults apply

1867
1868 <Expandable title="60 bug fixes">
1869 * Fixed a restored memory file's age note changing between requests after a compaction or resume, which caused prompt cache misses
1870 * Fixed `--forward-subagent-text` stream-json and SDK output dropping the messages of subagents spawned by a `context: fork` skill, and of forked skills invoked by a subagent or another forked skill
1871 * Fixed @-mention file suggestions being buried below MCP resources when using a custom `fileSuggestion` command or typing `@.`/`@./`
1872 * Fixed fullscreen mode placing background-task completion notices beneath a long turn's collapsed tool row instead of where they arrived; each notice now closes the open row
1873 * Fixed `claude plugin marketplace update` deleting a GitHub marketplace's local copy when the fetch failed and the marketplace was named after its repository
1874 * Fixed plugin and marketplace messages, logs and `claude plugin marketplace list` showing a password or token stored in a git, ssh or marketplace URL
1875 * Fixed a resumed cloud session leaving an unanswered question open in the transcript after a queued message superseded it
1876 * Fixed vim mode placing the cursor one character right after a dot-repeated "!" or a fast-typed "i!" switched a non-empty prompt into shell mode
1877 * Fixed fullscreen mode freezing or blanking for several seconds when scrolling up past a large file diff
1878 * Fixed a stray `</ccmemory>`-style closing tag occasionally appearing in responses
1879 * Fixed plugin messages, logs and the VS Code plugin dialog showing the wrong server for some git addresses
1880 * Fixed a terminal `API Error: 400` on every turn for users behind a network gateway that rewrites API error responses when a beta request header is rejected
1881 * Fixed sandboxed Bash commands on Linux reporting exit code 0 for failed commands when the shell is zsh
1882 * Fixed the Read tool hanging instead of reporting an error when part of a large file could not be decoded under memory pressure
1883 * Fixed `--resume`, the resume picker preview, resumed background agents and the transcript view failing on a session whose saved history contains a malformed task-reminder or @-file attachment entry
1884 * Fixed a crash when resuming a conversation whose transcript contains a malformed message entry, and a fullscreen crash when such a conversation received new messages while scrolled up
1885 * Fixed sessions failing to resume or start when their saved transcript contains a malformed message content block
1886 * Fixed Grep, Glob and @-file suggestions hanging or running out of memory on searches over the 20MB output cap, and system ripgrep reporting "no matches" instead of an error after a flood of warnings
1887 * Fixed `/rewind` in a forked or background session restoring a zero-filled or truncated file when the session's file-history backups could not be fully copied
1888 * Fixed fullscreen sessions sometimes exiting with "Claude Code exited after an unrecoverable interface error" when typing fast or holding a key with the slash-command dropdown open
1889 * Fixed background sessions crashing and restarting their worker when a command fed through stdin ran on a machine that had run out of file descriptors
1890 * Fixed a crash at launch when `~/.claude.json` holds a malformed `mcpNeedsAuthNoticed` value
1891 * Fixed `--resume` and `--continue` dropping a conversation's earlier thinking when a built-in tool it started with has since been switched off by a server-side flag
1892 * Fixed text selected with the mouse in the fullscreen `claude --resume` session picker never reaching the clipboard
1893 * Fixed plugin reload previews replacing a running session's extracted plugin files when the plugin was loaded from a `--plugin-dir` or `--plugin-url` archive
1894 * Fixed self-hosted runners with `--drain-wait-sec` losing the final result of a turn that finished during a SIGTERM drain; the runner now waits briefly for the turn to be reported
1895 * Fixed `SubagentStop` hooks with a specific `matcher` firing for every stopping subagent whose agent type was empty
1896 * Fixed sandboxed Bash commands being unable to write to project directories named `hooks/` or `config/`
1897 * Fixed Artifact updates failing with "File not found" after a session resumes on another machine or its scratchpad is cleared: the page's last published version is restored
1898 * Fixed `/update-config` writing `Write(path)` permission rules, which file permission checks don't match, instead of `Edit(path)` rules
1899 * Fixed four dead documentation URLs (Pricing, Computer Use, Skills, CLI) in the bundled claude-api skill's live-sources table
1900 * \[VSCode]
1897 * Fixed attachments recorded earlier in a conversation being re-rendered a
