9<Update label="2.1.302" description="October 16, 2026">
10 **Added**
11
12 * Added `CLAUDE_CODE_AUTO_MODE_MODEL` to choose the model the client-side auto mode classifier uses; it does not change the model for server-side auto mode
13 * Added an `Idle compaction` row to `/config` for turning idle compaction off or back on; the notices shown after an idle compaction now say how to turn it off
14 * Added a notice to `/design-sync` and `/design-login` that standalone Claude Design (claude.ai/design) closes by December 14, 2026
15 * \[Cloud sessions] Added a banner on a routine's page that says why its last run didn't start, such as your organization reaching its limit on concurrent cloud sessions
16
17 **Changed**
18
19 * Changed `claude -p` and Agent SDK sessions with no permission mode to start in `default` mode on third-party providers, with telemetry off or on a fresh install; `--permission-mode auto` keeps auto
20 * Changed fork subagents (`subagent_type: "fork"`) to be on by default in `claude -p`, the Agent SDK, the desktop app and VS Code, as they already are in the terminal; `CLAUDE_CODE_FORK_SUBAGENT=0` turns them off, and `claude mcp serve` never offers them
21 * Changed the desktop app and VS Code to always run the main conversation's subagents in the background, as the terminal does, rather than let Claude choose; a subagent's own Agent calls in `claude -p`, the Agent SDK, the desktop app and VS Code now run in the foreground by default
22 * Changed the `← for agents` footer hint to hide 10 seconds after a session opens; the count of agents waiting on you still shows
23 * Changed where the Claude in Chrome instructions sit in the system prompt so that new conversations can read them from the shared prompt cache
24 * Changed prompt and agent hooks so that at most 12 of one event run at a time; the rest wait their turn
25 * Changed the message shown when your organization's policy turns off `/feedback`: it now points to GitHub issues instead of an organization admin
26 * \[Claude Tag] Changed Claude Tag admin settings to organize Claude's access into four tabs: Bundles, Connectors, Skills and plugins, and Channels
27 * \[Claude Tag] Changed the Roles page in organization settings to group the roles created for Claude Tag channel managers in a collapsed section below your organization's own roles
28
29 <Expandable title="7 improvements">
30 - Improved startup time with many plugins enabled: plugin command and agent files now take far fewer file system calls to load, most of all on Windows
31 - Improved auto mode with the server-side classifier: a conversation too long for the safety check is now compacted, instead of every checked tool call being denied
32 - Improved the message when a background session reopened from another folder has no LLM gateway: it now says why, instead of "Not logged in"
33 - \[Cloud sessions] Improved the error shown when a cloud session fails to start: it now says "Connection lost" or "Server error" instead of "Something went wrong"
34 - \[Claude Tag] Improved repository search in Claude Tag admin settings to cover up to 100 connected GitHub accounts and find private repositories past the first 5,000 of a GitHub App install
35 - \[Claude Tag] Improved Add place in Claude Tag admin settings to list a channel you type or paste right away, instead of only after your organization's full channel list has loaded
36 - \[Claude Tag] Improved Add > Domain on a workspace's or channel's page in Claude Tag admin settings to be available once that page loads, not only after every channel has loaded
37 </Expandable>

39 <Expandable title="43 bug fixes">
40 * Fixed a "Prompt is too long" error when stopping a turn while the conversation was being compacted
41 * Fixed requests failing with "diagnostics: Extra inputs are not permitted" after switching to Vertex or Bedrock mid-session
42 * Fixed the Read tool loading an image file of any size, or a pipe or device named like an image, entirely into memory; image sources over 128 MB are now refused
43 * Fixed `/autocompact` and `/effort` saving to the wrong model when a gateway names Opus 4 or 4.1 with a prefix, such as `anthropic/claude-opus-4-1`
44 * Fixed a prompt cache miss when a tool added mid-session was loaded again through ToolSearch or after compaction
45 * Fixed `claude plugin` and other subcommands sometimes exiting before a queued settings or config write finished, which could lose the change or leave a `.tmp` file behind
46 * Fixed plugin marketplaces re-cloning on every refresh, and newly installed git plugins showing version "unknown", when git defaults to the reftable ref format
47 * Fixed the PowerShell tool not finding commands in a plugin's `bin/` folder, and reporting an error when a search that finds nothing (rg, grep, findstr, git grep) is piped into `Select-Object` or another formatting cmdlet
48 * Fixed Claude in the desktop app pointing you to claude.ai settings or `/mcp` to authorize or reconnect an MCP server where that option isn't available
49 * Fixed artifact publishes sometimes failing when Claude sent an empty list of edits, and Claude retrying an artifact update the wrong way after a newer version of the artifact turned it away
50 * Fixed `classifier_category` missing from OpenTelemetry `tool_decision` events for most auto mode classifier blocks, and new `tool_decision` attributes pushing out `tool_use_id`, `tool_source` and `tool_parameters` when `OTEL_LOGRECORD_ATTRIBUTE_COUNT_LIMIT` is low
51 * Fixed rows in the agents view staying blank after moving down a long list or folding a section
52 * Fixed `claude remote-control --help` not printing its usage and exiting when not signed in
53 * Fixed `/design consent` and `/design revoke` suggesting `/design-login` when they fail in a cloud session, where it isn't available; the message now points to claude.ai/design/settings
54 * Fixed MCP servers showing no tools, or every tool call failing, when the server negotiates protocol version 2026-07-28 but omits `resultType`, `ttlMs` or `cacheScope`
55 * Fixed prompt suggestions spending usage credits on models your plan pays for only with credits: they are now skipped after a reply billed to credits
56 * Fixed URLs written in backticks being clickable only on their first row when they wrap; the whole URL is now one link in terminals that support hyperlinks
57 * Fixed `claude plugin details <name>@builtin` suggesting `claude plugin list`, which never shows built-in plugins, when the plugin isn't found; it now points to `/plugin`
58 * Fixed an emoji that a link starts inside wrapping one column too wide, which hid it in question previews and turned tables into lists
59 * Fixed worktree isolation refusing to create or resume worktrees under git 2.56 or later when a stray `.git` file points at a directory that doesn't exist
60 * Fixed a cloud session's cost and usage restarting from zero after the session resumed in a new process
61 * Self-hosted runner: Fixed git fetches failing with "bad object refs/heads" in sessions that reuse a checkout stored in git's reftable format
62 * Windows: Fixed every file write being refused or asked about for projects on exFAT or FAT32 drives, including in sessions started with `--plugin-dir`
63 * \[VSCode] Fixed text after an unclosed code block in a list showing as plain text while a reply streams, then turning into code
64 * \[VSCode] Fixed MCP server sign-in from the panel opening a broken authorization page when the server URL contains a query string
65 * \[VSCode] Fixed the `@browser` banner saying "Browser connected" when no browser with the Claude extension can be reached
66 * \[Cloud sessions] Fixed "Rewind to here" failing on every message except the newest in cloud sessions; self-hosted runners need Claude Code v2.1.246 or later
67 * \[Cloud sessions] Fixed the pull request status bar in cloud sessions flipping a pull request with merge conflicts back to ready while GitHub rechecked it
68 * \[Cloud sessions] Fixed routine runs showing as Completed after their cloud session stopped unexpectedly, and as Cancelled when archived before they started, instead of failed
69 * \[Cloud sessions] Fixed the diff view in cloud sessions missing changes or failing to load after the session's GitHub repository was renamed or moved
70 * \[Cloud sessions] Fixed a scheduled routine run that failed partway being run again from the start an hour or more later, which could repeat work such as posting the same report twice
71 * \[Cloud sessions] Fixed an open cloud session sometimes not showing messages sent from another device until you reloaded the page or clicked away and back
72 * \[Remote Control] Fixed a subagent's pane spinning forever in a Remote Control session after your computer goes offline; it now says Remote Control is disconnected
73 * \[Claude Tag] Fixed "is thinking…" staying up under a mention in a Slack channel or DM after Claude answered it by editing one of its earlier messages
74 * \[Claude Tag] Fixed URLs in code blocks under a numbered or bulleted step of Claude's Slack replies being wrapped in angle brackets, which broke copied commands
75 * \[Claude Tag] Fixed HEIC, SVG, TIFF and BMP images attached in Slack never reaching Claude; they now arrive as files in its working files, like other file types
76 * \[Claude Tag] Fixed new channel managers losing access to Claude in Slack in organizations that restrict Claude Tag by role; the manager role now also grants Claude Tag in Slack
77 * \[Claude Tag] Fixed custom connectors whose MCP servers share one host showing as a single connector in Claude Tag admin settings; each server is now its own connector
78 * \[Claude Tag] Fixed Claude in Slack sometimes answering a direct message with "DMs are temporarily unavailable" and dropping it when a single Slack lookup stalled; it now retries first
79 * \[Claude Tag] Fixed direct messages with Claude on a Slack Enterprise Grid ignoring Slack's workspace dropdown; they now run under the connected workspace you last opened Claude in
80 * \[Claude Tag] Fixed Claude in Slack's notice for a channel's monthly spend limit saying a channel manager can raise it; it now names an organization owner and links the usage page
81 * \[Claude Tag] Fixed links in Claude's Slack replies absorbing the closing bold or italic marks, or full-width punctuation, right after them, which broke the link and the formatting
82 * \[Code Review] Fixed Code Review setup not resuming after you leave to connect GitHub; back in admin settings, it now reopens at the repository picker

from line 1922
18451922 * \[Cloud sessions] Fixed the next run time shown for an hourly routine being 30 minutes off for people in half-hour-offset time zones such as India
18461923 * \[Claude Tag] Fixed auto-join channel patterns saved for one workspace in Claude Tag admin settings being ignored on an Enterprise Grid org-wide install; Claude now joins matching new channels
18471924 * \[Claude Tag] Fixed Claude not responding in an Enterprise Grid channel shared between two workspaces of one organization when the channel's Claude Tag version was saved from the other workspace
1848 * \[Claude Tag] Fixed the earlier Claude in Slack app's progress card for sessions on a GitHub Enterprise Server repository: it now names the repository and offers a working Create PR button
1849 * \[Claude Tag] Fixed Slack threads whose model has been retired falling back to another model on every reply, slower and with a fallback note each time; the thread now moves to a working model
1850 * \[Claude Tag] Fixed files Claude uploads to Slack not being able to carry a caption containing a table; captions now render with the same formatting as replies
1851 * \[Claude Tag] Fixed Claude's threads in Slack's Agents & tools view sometimes being listed under their first message instead of their name; later renames now update the list too
1852 * \[Claude Tag] Fixed removing a GitHub organization's grant from an access bundle's Repositories tab in Claude Tag admin settings failing to save after that GitHub organization was disconnected
1853 * \[Claude Tag] Fixed Claude always replying "Couldn't check this channel just now" in a channel shared with a Grid workspace it isn't added to; the notice now says which workspace needs the app
1854 * \[Claude Tag] Fixed the cost and token totals in Claude's reply footer reading many times too high after the session's cloud worker restarted

1857
1858<Update label="2.1.281" description="September 23, 2026">
1859 **Added**
1860
1861 * Added Claude apps gateway support for newer Claude Desktop keys in `desktop` policy blocks, including `blockReadsOutsideWorkingDirectories` and `disableBypassPermissionsMode`
1862 * Added `assume_role` on Claude apps gateway Bedrock upstreams: the gateway calls Bedrock as an IAM role it assumes through STS, in another AWS account if needed, optionally one session per developer
1863 * Added `guardrail: {id, version}` on Claude apps gateway Bedrock upstreams to apply an Amazon Bedrock guardrail to every request sent through them (set it on all Bedrock upstreams or none)
1864 * Added `telemetry.resource_attributes` to the Claude apps gateway config, to put fixed labels on the telemetry of Claude Desktop and `/login` sessions
1865 * Added `"attribution": false` in `settings.json` to hide all commit and PR attribution; older CLI versions skip a settings file that holds it, so keep the object form in files shared across versions
1866 * Added MCP URL-mode elicitation on 2026-07-28 protocol connections, so servers can ask Claude Code to open a browser-based flow; no waiting dialog is left on screen when the server has no way to confirm completion
1867 * Added MCP server checks to `claude plugin validate`: it reports `.mcp.json` entries that would be silently dropped at load, undeclared `${user_config.*}` references, and insecure URLs
1868 * Added an auto mode recommendation to `/insights` that estimates how many permission prompts auto mode could have handled in your recent sessions
1869 * Added a scrollbar to the `/skills`, `/mcp` and `/plugin` Installed lists in fullscreen mode, like the one `/workflows` now has: it appears while the mouse is over the list and can be clicked or dragged
1870 * \[VSCode] Added a Continue/Stop prompt in the VS Code and JetBrains panels when auto mode falls back to billed classifier requests, replacing the unanswerable warning line
1871 * \[Claude Code on the web] Added a Fast mode switch to the composer's model menu in cloud sessions, shown when your plan includes fast mode and the selected model supports it
1872 * \[Claude Code on the web] Added a settings shortcut on the GitHub setup tip and a "Troubleshoot GitHub connection" link in the repository pickers, both opening your GitHub connection page
1873 * \[Claude Tag] Added a short line in the Slack thread after someone presses Stop, naming who stopped Claude's response and saying to mention @Claude to continue
1874
1875 **Changed**
1876
1877 * Changed send now (ctrl+enter or ctrl+x ctrl+s) to move running tools to the background instead of cancelling the turn
1878 * Changed auto mode so that, where its classifier review runs server-side, read-only and sandboxed shell commands also wait for that review and are blocked when it flags them
1879 * Changed `CLAUDE_CODE_AUTO_MODE_SERVER` to also apply on a direct Anthropic API connection: `0` opts out of the server-side auto mode classifier (the local classifier then counts toward usage), `1` opts in
1880 * Changed the dangerous `rm` prompt in `--dangerously-skip-permissions` and auto mode to wait 2 minutes for an answer, then deny the command with a rewrite hint so unattended sessions keep going (`CLAUDE_CODE_DISABLE_DANGEROUS_RM_TIMEOUT=1` turns this off)
1881 * Changed AGENTS.md support to also work on Amazon Bedrock, Google Vertex AI, Microsoft Foundry, LLM gateways, and sessions with telemetry disabled
1882 * Changed Claude apps gateway to refuse to start when a `managedMcpServers` entry's `envHelper` path starts with `\??\` or `/??/`, a path form current Claude Desktop refuses to run
1883 * Changed self-hosted runners to pass system prompts to Claude Code as private files instead of command-line text, so large prompts no longer fail the launch; a wrapper or `command` hook that appends `--system-prompt` or `--append-system-prompt` must switch to `--system-prompt-file` or `--append-system-prompt-file`
1884 * Changed queued messages to show in the conversation above the spinner instead of under it
1885 * Changed the session artifact links under the prompt into one footer pill (`⧉ name` or `⧉ N`) that opens `/artifacts`, which now lists this session's artifacts first
1886 * Changed the Artifact tool to let Claude load scripts from unpkg.com in artifact pages
1887 * Changed hovering a list row in fullscreen mode, including in `/config`, to tint the row instead of drawing a second ❯ pointer beside the focused row's
1888 * Changed /mcp: each server's row now starts with its status icon and name, says its state once, and in a narrow terminal drops trailing facts like "managed" before shortening the name
1889 * Changed /workflows: each run's row leads with its status icon and elapsed time, and a narrow terminal keeps the run's name and time, dropping the agent and token counts first
1890 * Changed Remote Control attachment downloads to reuse connections and to skip files already downloaded in the session
1891 * Changed MCP resource lists (the resource list tool and @-mention suggestions) to skip MCP Apps UI resources; reading one by URI still works
1892 * Changed `claude plugin uninstall --json` and the /plugin dialog to say a plugin's data was kept when its folder stays because another installed plugin uses it or install records cannot be read
1893 * Changed the background tasks list (`/tasks`): pressing `x` on a running `/ultrareview` now asks for confirmation before stopping the review
1894 * Removed the leftover "(removed)" `/agents` entry from the command menu and `/help`; typing `/agents` still explains where the wizard went
1895 * \[Claude Tag] Changed the routine list Claude gives when asked in a Slack thread to show that thread's own scheduled tasks by default instead of every routine in the channel
1896
1897 <Expandable title="33 improvements">
1898 - Improved Claude Desktop sign-in and usage-limit error messages to point at the app instead of terminal commands
1899 - Improved startup: managed settings and policy fetches no longer retry requests that can never succeed
1900 - Improved interactive startup time: git reads, startup telemetry and the Bedrock/Vertex model-upgrade checks no longer run before the first frame
1901 - Improved the time to resume long sessions that read many files; the restored file cache now matches the files as they were read
1902 - Improved the time to resume very long sessions that have been compacted, most noticeably through the Agent SDK and Claude Desktop
1903 - Improved "Prompt is too long" recovery in sessions dominated by one very large first prompt: that prompt is now summarized on its own instead of being left out of the summary
1904 - Improved auto mode after resuming a session in a new process: the permission classifier can now reuse its earlier prompt cache instead of rewriting it
1905 - Improved the auto mode denial message so Claude treats a denial as covering the outcome, not only the exact command
1906 - Improved the dangerous-rm check to also flag a removal at a shell variable followed by a top-level directory name, at a variable derived from the working directory, or at a backslash-only target
1907 - Improved sandbox guidance on macOS: when a local dev server can't bind a port, Claude now points to `sandbox.network.allowLocalBinding`
1908 - Improved `--agents` to accept the path to a JSON file (with `-p`) as well as inline JSON, and to allow an empty `prompt`
1909 - Improved `/batch` to run where a WorktreeCreate hook provides the agent worktrees, not only inside a git repository
1910 - Improved plugin hook-failure errors to name the offending plugin, and added a `claude plugin validate` warning when a shell-form hook leaves `${CLAUDE_PLUGIN_ROOT}` unquoted (it breaks on plugin paths with spaces)
1911 - Improved the `/` menu, `/skills`, `/context` and the `/plugin` Installed list to show skills synced from claude.ai by their short name when no other command uses it, not `anthropic-skills:<name>`
1912 - Improved `/deep-research` reliability on long research briefs by removing unused required fields from the scope step's output
1913 - Improved the writing in published artifact pages: the bundled artifact-design skill now asks Claude for plain, direct prose
1914 - Improved artifact publishing on slow connections: large page uploads are now sent compressed
1915 - Improved the large CLAUDE.md startup notice to also count instruction files together, so many mid-sized files and @-imports are caught
1916 - Improved debug logs to name settings `env` variables ignored because the session's launch environment already sets them
1917 - Improved keyboard navigation in tabbed dialogs such as `/permissions` and `/usage`: ↑/↓ move focus between the tab row and the content, and a list responds to keys only while it has focus
1918 - Improved `/help` and `/sandbox`: ←/→ and Tab switch tabs from inside a tab's list, and ↓ on an empty Custom commands tab in `/help` no longer leaves the keys stuck until Esc
1919 - Improved `/install-github-app`, `/desktop`, the `/permissions` auto mode environment prompts, and the `/plugin` "Add marketplace?" and "Run this command?" prompts: they now use the standard dialog frame with key hints, and Ctrl+C or Ctrl+D cancels them on the second press like other dialogs
1920 - Improved the `/workflows` and `/mcp` lists: they page (PgUp/PgDn, Home/End) and take j/k and the mouse like other lists, their arrows follow `select:previous`/`select:next` rebinds, and
1925 * \[Claude Tag] Fixed the earlier Claude in Slack app's progress
