9<Update label="2.1.293" description="October 7, 2026">
10 * Added Claude Haiku 5.5 (`claude-haiku-5-5`), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K)
11 * Added `agentType` to the `subagentStatusLine` payload, so scripts can tell custom subagent types apart
12 * Added `isDeferred` to `$.tool.register` for mods: `false` lists the tool's schema in the prompt from the start instead of behind tool search
13 * Fixed Claude sometimes treating its own last actions before a context compaction as done after it, and retracting or redoing finished work
14 * Fixed a memory leak where an HTTP MCP connection kept every request it had sent until it closed
15 * Fixed a message sent while Claude was working being lost when `←` moved the session to the background; if a queued message can't move, `←` now stays put and says so
16 * Fixed `/model` effort ←/→ wrapping past the highest or lowest level, which could accidentally save Low as a model's default effort
17 * Fixed `/tui` disconnecting Claude in Chrome in a session started with `--chrome`, and ignoring `--no-chrome`
18 * Fixed Claude being told to continue or message subagents with `SendMessage` in sessions, including resumed ones, where a host, a permission rule or a `--tools` list removed that tool
19 * Fixed subagents and `--agent` sessions being told a built-in tool was disabled for the whole session when only their own tool list left it out
20 * Fixed a claude.ai-synced skill's edited description sometimes not reaching the model until a new conversation or `/clear`
21 * Fixed `claude logs`, `stop`, `kill`, `rm` and `claude daemon status`, `stop`, `uninstall` sometimes signing you out when your login had expired or was about to
22 * Fixed the footer's agents count disappearing after a momentary failure to read the sessions folder (for example, too many open files)
23 * Fixed a custom agent named `worker` being shown as "Agent" when it starts, and the agent detail dialog's title losing the agent type once the agent finishes
24 * Fixed the Artifact tool's transcript row briefly reading `Artifact("(unprintable path)")` while a publish call was still streaming in
25 * Fixed the `/ultrareview` upload on Linux wrongly refusing some repositories, such as one inside another checkout, over a settings file that "could not be parsed" while a sandboxed command was running
26 * Fixed the `/ultrareview` upload's refusal over split-index files advising a git command that could leave git unable to read its index
27 * Fixed replies in very long Remote Control and cloud sessions that could still appear a block at a time instead of streaming in
28 * Fixed Remote Control uploading a session's starting history again after every credential recovery
29 * Fixed PushNotification reporting "Remote Control inactive" in sessions started with `claude remote-control`
30 * Fixed a mod's hooks on `classic.*` events being skipped while the plugin hooks worker restarts, which left settings hooks to answer without them
31 * Fixed `claude plugin test` failing for mods that call `$.session.append`; tests can read the appended rows back with the new `mock.session`
32 * Fixed `claude plugin eval` refusing every Bash-granting run on Macs with Docker Desktop (links under `~/.docker/bin`); the refusal now names which part of a credential store held the link
33 * Fixed the Claude apps gateway refusing to start when a `desktop` policy sets Claude Desktop's built-in browser keys, such as `builtinBrowserEnabled`
34 * Fixed `claude agents` offering bypass permissions that background sessions then ignored when consent was saved only in `.claude/settings.local.json` or a `--settings` file; it now asks for consent first, and a session that ignores bypass shows a short notice that stays
35 * Fixed `←` backgrounding a session after 10 seconds while the prompt held unsent text (it now cancels the move) or a question was waiting for your answer
36 * Fixed Esc, or No without feedback, on a permission prompt not stopping the turn when `←` had just been pressed to move the session to the background
37 * Fixed the agents view briefly replacing the session list with placeholder rows when the sessions folder could not be read (for example, too many open files)
38 * Fixed path-scoped rules and nested CLAUDE.md files not loading when Claude views a file with a single-file cat, head, tail, sed -n or grep command in the Bash tool instead of the Read tool
39 * Fixed pasted text that begins and ends with the same words sometimes being sent to Claude as if it had been typed
40 * Fixed a skill name in pasted text being treated as typed when an accent typed or pasted right after the paste merged into its last letter
41 * Fixed `/feedback` returning to the drafts list after Ctrl+O or Ctrl+Z while a report was sending, leaving the send impossible to cancel
42 * Fixed `claude purge` stopping silently (exit 0, or a hang in a terminal) when a file or folder could not be deleted; it now deletes the rest, lists what it could not delete, and exits 1
43 * Fixed keybindings.json checks: a lone " " (space key) is no longer reported as an error, and keys like "ctrl+ k" now get a warning
44 * Fixed vim mode `>>` and `<<` on a line of only spaces leaving the cursor past the end of the line, where a following `x` deleted nothing
45 * Fixed vim mode: after deleting whole lines in Visual mode (`V` then `d`) the cursor lands on the first non-blank, and `.` after it acts on the cursor's line
46 * Windows: Fixed stopping a status line, hook, or shell command sometimes terminating an unrelated process that had been given the same process ID
47 * Reverted the auto mode denial message change from 2.1.281 that told Claude a denial covers the outcome, not only the exact command
48 * Reverted the 2.1.290 fix for cloud sessions staying asleep after a container restart lost a pending `/loop` wakeup or scheduled task; Claude is no longer told, and the session stays asleep
49 * Improved startup for Team and Enterprise organizations: policy and managed settings are fetched earlier, and a stalled request is retried after 3 seconds
50 * Improved Claude in Chrome: fewer page actions are refused when the browser is slow to report its tabs
51 * Improved the Claude in Chrome message in cloud sessions when the browser can't be reached: if you belong to more than one organization, it now says the extension must be signed in to the same one, and how to change that
52 * Improved the Bash edit diff note to say the listed files changed while the command ran, which can include writes by other processes
53 * Improved artifacts: Claude pins libraries to exact versions two weeks old or older
54 * Changed claude.ai skill syncing to check for changes about every 40 minutes, instead of every 10, while no session is in use
55 * Changed the order of agent lists and of MCP servers announced to the model: names with non-ASCII characters now sort after ASCII names
56 * Changed OpenTelemetry `claude_code.at_mention` logging to emit at most 100 agent and 100 MCP-resource events each time a prompt is read
57 * Self-hosted runner: Changed the orchestrator to sleep 4 to 6 seconds between polls instead of a constant 5, so several replicas for one environment stop polling at the same moment
58 * \[Claude Tag] Fixed Claude in Slack saying a workspace isn't set up in Enterprise Grid channels shared across workspaces when Slack labels a message with a workspace that isn't connected
59 * \[Claude Tag] Fixed Claude in Slack stopping mid-task in a channel when an admin changed the channel's connectors, plugins, skills or rules; the change now applies once Claude finishes
60 * \[Claude Tag] Fixed asking Claude in Slack to run a thread's routine now with extra notes starting a separate run that couldn't post back; the run now continues in that thread
61 * \[Claude Tag] Fixed an access bundle's Add a connector dialog in Claude Tag admin settings showing every Google connector as connected after one Google sign-in
62 * \[Claude Tag] Improved Claude Tag admin settings to list an Enterprise Grid that isn't connected yet, with a Connect button
63 * \[Claude Tag] Changed Claude in Slack to join announcement channels, where only admins can post, without posting its intro
64 * \[Claude Tag] Changed the limit on channel rules in Claude Tag admin settings from 20 to 50 for each workspace and for the organization-wide Slack page
65 * \[Code Review] Improved Code Review's Add a repository dialog to list each repository that couldn't be added and why, such as missing GitHub write access

968<Update label="2.1.292" description="October 6, 2026">
1069 * Added `--marketplace <source>` to `claude plugin install`: adds the marketplace if needed, under the same policy checks as `claude plugin marketplace add`, then installs the plugin from it
1170 * Added an `effort` parameter to the Agent tool, so Claude runs a sub-agent at the effort level you ask for
from line 1748
16891748 * Improved `/web-setup` errors: a refused GitHub token now lists the likely reasons and the fix, and a connection failure names a configured proxy or TLS certificate problem
16901749 * Improved the in-session SSL certificate and proxy connection errors to name the error code and what to fix, such as `NODE_EXTRA_CA_CERTS` for an untrusted corporate CA
16911750 * Improved the error when a cloud session can't be created because your Claude login expired or was revoked: it now tells you to run `/login`
1692 * Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authenticate (`/mcp`)
1693 * Changed auto mode on Bedrock, Vertex and Foundry to use the local classifier by default for now; set `CLAUDE_CODE_AUTO_MODE_SERVER=1` to use the platform's server-side classifier
1694 * Changed `OTEL_LOG_TOOL_DETAILS=1` to also include real agent, skill, plugin and MCP server names on cost and token metrics
1695 * Changed sign-in with a Claude account to also request access to your claude.ai plugins
1696 * Changed `/bug` and `/feedback` reports to include only model-behavior params (model, system prompt, tools) from the last API request, omitting request metadata and `CLAUDE_CODE_EXTRA_BODY` fields
1697 * \[VSCode] Fixed "Report a problem" still appearing, and `/bug` / `/feedback` opening a report form, for organizations that have product feedback disabled
1698 * \[VSCode] Fixed a red "Claude Code process exited with code 4294967295" banner appearing after completed turns on Windows
1699 * Windows: Improved the network-path permission check for UNC paths when a mapped network drive was added with `--add-dir`
1700 * \[Claude Code on the web] Fixed routines losing access to an organization connector, and still calling the old one, after an admin removed and re-added that connector
1701 * \[Claude Code on the web] Fixed creating a self-hosted environment from organization settings occasionally failing with a server error and leaving a half-created environment behind
1702 * \[Claude Code on the web] Changed the admin "Share cloud sessions" setting to live under Data and privacy instead of the Claude Code page, where Data and privacy admins can also manage it
1703 * \[Claude Code on the web] Added a "Discard unsaved changes?" confirmation before the New routine page or the Edit routine dialog throws away a routine name, prompt or edit you typed
1704 * \[Claude Code on the web] Removed the full-page desktop-app download screen that new users without a cloud environment saw on Mac and Windows; they now go straight to setup
1705 * \[Claude Code on the web] Improved the routine detail page: menu and rename in the breadcrumb, the on/off switch and Run now at the top, and run history beside the routine's settings
1706 * \[Claude Tag] Fixed Claude going silent minutes after reinstalling the app when an Enterprise Grid was disconnected but one of its workspaces stayed connected
1707 * \[Claude Tag] Fixed scheduled tasks set up in an organization-shared private Slack channel silently never posting; they now keep running in the thread they were created in
1708 * \[Claude Tag] Fixed replying in an older Slack thread while Claude is mid-task sometimes restarting it from scratch and losing work it had not pushed yet
1709 * \[Claude Tag] Fixed Claude occasionally dropping a message with an incorrect "couldn't find a Claude Code environment" notice right after your account token refreshed
1710 * \[Claude Tag] Fixed AWS connections refusing region-less endpoints such as Budgets, Savings Plans, WAF Classic and Import/Export; Global Accelerator requests now sign correctly
1711 * \[Claude Tag] Improved AWS connection failures: when a request can't be signed, such as a hostname with no region, Claude is told why and how to fix it instead of a bare error
1712 * \[Claude Tag] Fixed OAuth client-credentials and JWT-bearer connections failing with providers that return a lowercase token type; requests now send the standard Bearer scheme
1713 * \[Claude Tag] Fixed adding a channel manager being refused on Enterprise Grid shared channels, on channels where Claude hasn't been used yet, and on legacy private channels
1714 * \[Claude Tag] Changed Claude to start watching related public channels on its own, such as an incident channel a conversation depends on, instead of only when asked
1715 * \[Claude Tag] Fixed the admin Memory page not listing Slack channels Claude set up on its own even when they had saved memory; admins can now open, edit and delete that memory
1716 * \[Code Review] Fixed merging the base branch into a PR whose earlier review listed "Additional findings" triggering a full re-review; these pushes now get the lighter follow-up review
1717 * \[Code Review] Fixed a whole REVIEW\.md being ignored because of an @-mention, a code span wrapped across lines, or a backticked HTML tag; only lines linking to changed files are withheld
1718 * \[Code Review] Improved suggested fixes to say what the fix must keep working when other code depends on the behavior being changed
1719 * \[Code Review] Improved review comments that point to a second affected location to state that location's issue in a full sentence instead of a cut-off stub
1720 * \[Code Review] Fixed `/ultrareview --post` so a retry after a GitHub error posts the findings comment exactly once instead of never or twice; the comment now names the reviewed commit
1721 * \[Code Review] Fixed empty or content-identical pushes being re-reviewed on GitHub repositories whose owner or name contains a capital letter; these pushes are now skipped

1725 * Bug fixes and reliability improvements
1726</Update>
1727
1728<Update label="2.1.271" description="September 14, 2026">
1729 * 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
1730 * 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
1731 * 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)
1732 * 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
1733 * 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
1734 * 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`
1735 * 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
1736 * 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
1737 * 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
1738 * Fixed the tool and command lists not updating when the organization policy finishes loading after startup or changes mid-session
1739 * 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
1740 * 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
1741 * 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
1742 * Fixed `/fast off` answering "Fast mode unavailable" instead of turning fast mode off when the organization has fast mode disabled
1743 * 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
1744 * 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
1745 * Fixed Bash permission checks missing the file that `fmt`, `column` and similar commands read when it follows an option the checker doesn't recognize
1746 * 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`)
1747 * Fixed Bash permission checks so that shell variable declaration flags cannot misrepresent the command being run
1748 * Fixed Bash commands with two directory changes, a subshell, or a `cd`+`git` chain skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories`
1751 * Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authentic
No line in this hunk matches that.
