Run `claude --version` to check your installed version.

<Update label="2.1.232" description="August 13, 2026">
  * Subagent forking is now on by default: a `subagent_type: "fork"` subagent inherits the full conversation and prompt cache, and non-teammate agent spawns in interactive sessions now run in the background by default
  * Type `@` in the prompt to mention another Claude session by name; Claude then uses `SendMessage` to reach that session directly
  * `SendMessage` now delivers to a bare name that exactly matches one live session, instead of asking to confirm with a ref first
  * Interactive sessions on one machine now keep unique names: starting or renaming a session to a name another live session already uses gives it a `name-word-word` variant and tells you
  * Added `/config` rows for "Dialog expiry" and "Messages from your other sessions" (cross-session inbound accept/hold/refuse)
  * Added secret redaction for GitLab token families (`glrt-`, `gloas-`, `glptt-`, `glagent-`, `glimt-`, `glsoat-`, `glcbt-`, `glft-`, `glffct-`) and full redaction of routable `glpat-`/`gldt-` tokens; the `glab` CLI config store gets the same sandbox and credential-path protection as `gh`
  * Added GitLab support to plugin marketplaces: bare `gitlab.com` repo URLs (including nested subgroups) now clone like `github.com` URLs, and clone auth-failure hints name your actual git host
  * Settings: `additionalMarketplaces` and `allowedMarketplaces` are now accepted as friendlier aliases for `extraKnownMarketplaces` and `strictKnownMarketplaces`
  * Enterprise policy: a url-typed `blockedMarketplaces` entry for a bare repo URL keeps blocking that URL when the CLI classifies it as a git clone
  * Gateway: the `desktop:` overlay now accepts every released Desktop setting (was 11 hand-listed keys), validated at boot against Desktop's own schema; unknown or invalid keys fail boot
  * Gateway: empty `managed.policies[].match.groups`/`admin.admin_groups` entries and malformed `email_domain` values (empty, or containing `@`, whitespace, or commas) now fail at boot instead of silently matching no one or granting admin access
  * Fable 5 is offered as an advisor in `/advisor` again for organizations with Fable access, with usage-credits consent set up through `/model fable`
  * Fixed a PowerShell permission bypass where variable-writing parameters could silently overwrite `$PSDefaultParameterValues` and redirect later commands' file access
  * Fixed a Windows permission bypass where Git Bash followed Cygwin-style symlinks that path validation saw as regular files; writes through them now require permission approval
  * Fixed nested git repositories inheriting trust from a parent directory; each repository now requires its own trust confirmation
  * Fixed MCP connections hanging for the full 30-second connect timeout when a server fails to answer or sends a malformed reply to the protocol-version probe
  * Fixed Remote Control sessions hosted by a bridge inside a cloud session inheriting that session's transcript or credentials
  * Fixed Remote Control sessions started from Claude Desktop or an IDE appearing as a new claude.ai session each time the local session was resumed; they now reattach to the existing one
  * Fixed Remote Control sessions appearing unreachable to newly attached clients while idle
  * Fixed Remote Control bridge sessions not restoring conversation history when the session worker restarts
  * Remote Control: resuming a conversation whose session was deleted from claude.ai or the app now starts a replacement instead of failing with a message about your login (regressed in v2.1.227)
  * Fixed Cloud gateway `/login` exiting silently or leaving an unresponsive terminal after "Press Enter to continue" when managed settings failed to load; the reason is now shown
  * Fixed voice mode on native builds getting stuck on "listening…" when the voice service rejected the connection; the rejection is now shown immediately
  * Fixed mTLS client certificate rotation requiring a restart; Claude Code now reloads the rotated cert and key automatically on connection errors
  * Fixed malformed AWS or Vertex region values being used to build request URLs; they now fall back to the default region
  * Fixed stream idle timeout errors failing the request instead of recovering on Bedrock, Vertex, and gateway deployments
  * Fixed content-sized overlays containing truncated text rendering one column too wide, and start-truncated text collapsing to an ellipsis
  * Fixed a stray garbled character where a long shell-command or agent-description preview was cut off mid-emoji
  * Fixed a startup race that could silently unregister a plugin marketplace due to concurrent writes to `known_marketplaces.json`
  * Fixed `/update` and `/tui` refusing to restart while work that survives the relaunch was running
  * Fixed usage-limit guidance suggesting unavailable slash commands in SDK and remote sessions
  * Fixed the consent message for interactive `--advisor fable` launches, which told you to run `/model fable` in an interactive session that had just exited
  * Improved fullscreen streaming: long sessions stay responsive because the whole conversation is no longer re-normalized on every update
  * Improved the managed settings approval dialog: shows endpoint URLs, uses clearer wording for telemetry-only changes, skips routine OpenTelemetry options, and requires approval for server-managed sandbox binary overrides (`sandbox.bwrapPath`, `sandbox.socatPath`, `sandbox.ripgrep`)
  * `/feedback` and `/bug` now open immediately when invoked while Claude is responding, instead of waiting for the turn to finish
  * `/plugin install plugin@marketplace` now refreshes the marketplace first, so newly published plugins install without a manual marketplace update
  * `/code-review` at high, xhigh, and max effort now runs in a background agent like the other levels
  * Pasted and clipboard images are read without blocking the event loop
  * Remote Control now keeps reconnecting for about 30 minutes after a network blip and no longer drops after a few blips spread across an hour
  * Remote Control: resuming a conversation no longer silently takes Remote Control away from another Claude Code on the same machine that still has it; run `/remote-control` there to move it
  * Updated agent panel: completed subagents hide immediately with a `/tasks` footer hint, and the "↓ N more" overflow indicator moved left for visibility
  * Remote Control: the terminal now says whether a session was taken over by another device, ended from another app, or deleted, and stops suggesting a reconnect that would undo it
  * Bash input redirections (`< file`) are now permission-checked like their argument spellings on all platforms
  * Shortened the message shown when resuming a completed background agent
  * Cowork sessions no longer inline external @-imports from user-scope memory files
  * Hardened the auto-generated cross-session messaging socket directory on shared `/tmp`: a pre-planted symlink or another user's directory is now refused instead of used
  * Hardened the Linux filesystem sandbox against a protected-path bypass
  * Changed `sandbox.ripgrep` to be honored only from user, managed, and `--settings` settings; project settings can no longer override the sandbox's ripgrep binary
  * Removed the startup tip suggesting you create custom subagents, and the matching nudge in the `/powerup` tour
</Update>

<Update label="2.1.231" description="August 13, 2026">
  * Fixed MCP OAuth sign-in failing with a redirect URI mismatch for servers that use a pre-registered OAuth client, such as Slack
</Update>

<Update label="2.1.229" description="August 12, 2026">
  * Documented `claude remote-control --continue` for resuming the most recent Remote Control session
  * Added server-supplied Claude Code hook support for self-hosted runner sessions, matching managed-environment behavior
  * Added SSE keepalive pings to gateway streaming responses during long thinking pauses, preventing idle-timeout disconnects on Vertex and Bedrock upstreams
  * Added plugin marketplace `command` sources: a local command (e.g. an IDE) prints the plugin directory, which is re-resolved each session and applied without a restart; `mode: "link"` uses it in place
  * `ListAgents` now marks disconnected Remote Control sessions as `offline` and labels your cloud sessions as `cloud`
  * Fixed long responses partly disappearing while streaming and being printed twice in the terminal
  * Fixed a crash to the error screen (including on `--resume` of the affected session) when a tool call had a non-string `glob`, `file_path`, or `command` value
  * Fixed a RangeError crash when a progress bar or markdown table rendered in a very narrow terminal window (could also crash `claude --continue`/`--resume` at startup)
  * Fixed a crash on Windows when a tool call or message referenced a file by an extended-length (`\\?\`) or UNC path
  * Fixed auto mode failing on every tool call for users who disable the attribution header via `CLAUDE_CODE_ATTRIBUTION_HEADER` (direct Anthropic API connections)
  * Fixed `/model` rejecting Sonnet/Opus 1M for claude.ai subscribers using a custom `ANTHROPIC_BASE_URL` gateway
  * Fixed MCP OAuth with strict authorization servers by using `127.0.0.1` instead of `localhost` in the redirect URI
  * Fixed Remote Control clients showing a stuck working spinner after a slash command typed in the laptop terminal
  * Fixed the Claude Code Review workflow generated by `/install-github-app` completing without posting its review on the pull request
  * Fixed multi-second UI stalls after editing a file with thousands of IDE diagnostics while the IDE extension is connected
  * Fixed one-shot `claude plugin` commands leaving a stray liveness file that could prevent cleanup of outdated plugin versions
  * Fixed dynamic workflows inside CPU-limited containers using the host machine's core count instead of the container's CPU limit
  * Fixed a file-watcher handle leak after atomic file replacements, and an uncaught error on Windows when the scheduled-tasks watcher failed on a network or virtual filesystem
  * Fixed SDK and `--input-format stream-json` sessions getting a 400 API error when a whitespace-only message was submitted
  * Fixed conversations whose messages alone exceed the API's 32 MB request limit retrying compaction when no images or documents can be stripped; they now fail once with a clear message
  * Fixed OpenTelemetry export from Claude Desktop sessions being rejected by the Desktop-managed gateway when that gateway is also the telemetry endpoint
  * Fixed self-hosted runner and other remote sessions exiting at startup when `managed-mcp.json` is deployed and the server delivers MCP servers; those servers are now skipped with a warning
  * Fixed self-hosted runner repository preparation hanging on a Git Credential Manager prompt; git now fails fast when credentials are missing
  * Improved workflow fan-outs to stagger same-prefix sibling agents so subsequent agents read the cached prompt prefix instead of re-paying it (`CLAUDE_CODE_WORKFLOW_PREFIX_STAGGER_MS=0` disables)
  * Improved "prompt is too long" errors to explain why automatic compaction could not recover instead of only suggesting `/compact`
  * Improved sandbox: IPv6 literals in network domain lists are now bracketed (`[::1]:443`), and ambiguous spellings are enforced fail-closed and flagged by `/doctor`
  * Updated `/login` to repeat the `CLAUDE_CODE_OAUTH_TOKEN` override warning after a successful login
  * Changed `/commit-push-pr` so git/gh commands with dangerous flags (`--force`, `--amend`, `--no-verify`, etc.) are no longer auto-approved
  * Changed self-hosted runner Windows startup to require an explicit `--base-dir`; there is no default checkout directory on Windows
  * \[VSCode] "Report a problem" and `/bug` now open the built-in feedback dialog instead of a retired survey link
  * \[VSCode] Made the `/btw` side-question panel resizable by dragging its boundary, in both side-docked and stacked layouts
  * \[VSCode] Added session groups in the sidebar — right-click to create, rename, or delete; Cmd/Ctrl- or Shift-click to move several sessions at once
</Update>

<Update label="2.1.228" description="August 11, 2026">
  * Fixed interactive sessions that could stop redrawing entirely, while the process kept running, after a rare internal layout error
  * Fixed `git` / Git Bash not being found on Windows when Claude Code is launched from a parent folder of the git installation
  * Fixed `/tui` reverting the session to an earlier model when `/model` had been changed since the last response
  * Fixed cross-session messaging sometimes starting without an inbox in the first session after install or upgrade
  * Fixed Remote Control `/resume` while connected leaking the resumed conversation's title or history into the connected session
  * Fixed `claude self-hosted-runner` sessions failing on every fresh runner when the `checkout` hook fails for a repository the session doesn't push to; that repository is now skipped with a warning
  * Fixed self-hosted runners ending sessions in the gap between a background task finishing and the follow-up turn starting
  * Fixed session cleanup deleting contents inside a project's memory folder
  * Fixed background plugin-cache cleanup deleting a plugin's cache when its only version is a symlinked development checkout
  * Fixed a settings-merge issue where a marketplace entry redefined in a higher-precedence settings tier could inherit another tier's custom headers; marketplace entries now merge as whole entries
  * Fixed the deferred-tools reminder occasionally being sent to the model twice after a skill invocation
  * Hardened skills synced from claude.ai: they no longer shadow local commands or MCP prompts, their descriptions are sanitized and labeled, and on your machine their bodies don't run `!` commands or expand `@` files
  * Improved cross-session messages: the sender and body now display inline instead of a collapsed line, and messages to Remote Control sessions on other machines show your Remote Control session name as the sender
  * Improved Vertex AI credential handling: expired or missing Google Cloud credentials now fail within seconds instead of retrying for minutes
  * Improved compaction progress: the retry countdown and stall hint now appear during compaction instead of only a progress bar
  * Updated terminal title busy-spinner glyphs to reduce tab-bar jitter on some terminals
  * Changed the Write tool so newer models can overwrite an existing file they haven't read this session, matching the Edit tool's rules; older models still require the read first
  * Removed the outdated note about auto mode sessions costing slightly more from the first-use notice for Pro, Max, and Team plans
</Update>

<Update label="2.1.227" description="August 10, 2026">
  * Fixed feature flags being evaluated without the user's subscription tier when a session started with an expired login token, which could wrongly prompt Max plan users to enable usage credits for Fable
  * Fixed every Bash command failing under `claude-code-action` with `allowed_non_write_users` on GitHub-hosted runners
  * Fixed `/tui` bringing back a conversation that had been rewound to before its first message
  * Improved slash-command menu: blue now marks only the selected row, matched characters are bolded instead of recolored, and emoji or accented names keep their glyphs
  * Improved performance: fewer event-loop stalls on file-not-found suggestions and at-mention size checks
</Update>

<Update label="2.1.226" description="August 8, 2026">
  * Bug fixes and reliability improvements
</Update>

<Update label="2.1.225" description="August 8, 2026">
  * Added gateway spend-limit support to Claude Code's usage warning; the limit-reached message now names the cap, its reset time, and the operator's message (requires the gateway on 2.1.225)
  * Added a workspace trust prompt to `claude agents` for untrusted directories, matching the behavior of `claude`
  * Fixed a transient 401 replacing a long-lived `CLAUDE_CODE_OAUTH_TOKEN` with a stored login's short-lived token, breaking headless sessions until restart
  * Fixed MCP OAuth servers on macOS intermittently failing with a burst of 401 errors, as if never authenticated, after a keychain read timed out
  * Fixed auto mode counting a safety-filter refusal of its own permission check toward the consecutive-block limit; the action is still denied, but the model is now told to move on rather than retry
  * Fixed cross-session messages staying parked without a notice or expiry in headless sessions and during startup
  * Fixed conversation history breaking on Remote Control session resume after very large conversations were compacted
  * Fixed hovering over a session in another project in the agents list changing the directory the next agent starts in
  * Fixed `claude self-hosted-runner` registering and then failing every session when `--base-dir` cannot be created or written; it now exits at startup with a clear error
  * Fixed Claude Code on the web sessions being misreported as stuck, re-sending a growing event backlog on every reconnect
  * Improved Remote Control: photos attached from the Claude app are now shown to Claude directly instead of being read from disk with a separate tool call
  * \[VSCode] Fixed Focus view folding away the latest to-do list, a pending question's context, and settled answers; thinking-only folds show "Thought for Ns" and re-collapse when their turn completes
  * SendMessage can now start a conversation with your Remote Control sessions on other machines by name (`ListAgents` shows them as `name [ref]`), instead of only replying after they message you first
  * SendMessage: a Remote Control recipient you already confirmed is never swapped for a same-named session on this machine when its own list couldn't be checked
</Update>

<Update label="2.1.224" description="August 7, 2026">
  * Added self-hosted environments: `claude self-hosted-runner` turns your own machines or containers into a place Claude Code web, mobile, and desktop sessions can run, on Team and Enterprise plans
  * Added `archive` plugin source: install plugins from a zip over HTTPS without git or npm, with optional SHA-256 pinning
  * Added a cancel-and-confirm step when removing an unavailable paste changes a command's text
  * Added `ANTHROPIC_BEDROCK_REGION_PREFIX` env var for Bedrock to prefer a specific cross-region inference profile over the `AWS_REGION`-derived one
  * Added `crossSessionInbound` and `dialogExpiry` settings: cross-session messages sent to a session running with bypassed permissions are held for your approval, and messages to other sessions auto-deliver
  * Added sandbox credential-masking options: `extract` and `onExtractNoMatch` for structured env values, `decode: "jwt"` with `maskClaims` for JWT-aware masking, and `awsPairs`/`sigv4` for AWS SigV4 re-signing; these need `network.tlsTerminate` and are honored only from user, managed, or `--settings` settings
  * Added cross-session `SendMessage`: Claude Code sessions can now message each other, on any of your machines, with `ListAgents` to discover them (macOS and Linux)
  * Fixed long (>200 char) project paths resolving to another project's session directory under a shared sanitized prefix; session list, rename, fork, delete and `/resume` no longer cross projects
  * Fixed `SendMessage` reporting "Message sent" when the write to a teammate's inbox had actually failed; failed deliveries are now reported as errors
  * Fixed sandbox filesystem deny entries written with a trailing slash (e.g. `denyRead: "~/.aws/"`) being silently bypassable on Linux and macOS
  * Fixed sandbox violation details never appearing in Bash tool results; Claude now sees which file or network access was denied and why
  * Fixed MCP tools that connect mid-turn being deferred for tool search without their names announced to the model
  * Fixed plugin install records being silently corrupted when the same plugin is installed in multiple projects
  * Fixed recalled or restored paste content occasionally attaching wrong data or silently losing text when the paste had aged out or placeholder numbers collided
  * Fixed copy-on-select on Wayland sometimes not reaching the clipboard; the two selection writes no longer race
  * Fixed the feedback survey's transcript share silently failing on long sessions; a failed share now shows an error instead of a success message
  * Fixed Remote Control auto-start intermittently failing with "Remote credentials fetch failed" on a cold start with a stale login token
  * Fixed Remote Control and SDK clients showing a blank "(no content)" message after `/clear` and other output-less commands
  * Fixed a Remote Control session recreated after its server session expired uploading prior local conversation history into the new session
  * Improved fullscreen mode to keep the full pre-compaction history in scrollback across repeated compactions, instead of only the most recent interval
  * Improved Remote Control: attached web and mobile clients now see compaction progress and the post-compaction boundary instead of a silent pause; `/clear` resets now propagate to attached clients
  * Improved Remote Control: connection failures now show a persistent failure indicator with details and a reconnect shortcut, instead of only an 8-second toast
  * Removed the 200-subagent-per-session spawn cap; long-running sessions no longer refuse new agents (concurrency and depth limits still apply)
  * Changed managed settings: the approval prompt no longer re-appears after re-login or org switching when the organization's settings are unchanged
  * Changed the feedback-survey transcript share: with your consent it now also uploads the last request's model settings — the system prompt (which includes your `CLAUDE.md` instructions), tool definitions, and model parameters. Secrets are redacted as before, and these fields are dropped first if the share is too large
  * Changed the Bash tool description to always note that command output is displayed to the model, not reliably to the user
  * Changed recalled paste placeholder numbers to renumber when accepted into the input
  * Changed Remote Control to archive the stale server session instead of leaving a dead one listed when a fresh session is minted after compaction or `/resume`
  * \[VSCode] Fixed the extension showing Remote Control as connected after the connection failed
  * Fixed a session resume silently reconnecting Remote Control after the user turned it off (`--resume`, SDK hosts, and the VS Code extension)
  * \[VSCode] Fixed sessions not honoring `remoteControlAtStartup` when explicitly enabled
</Update>

<Update label="2.1.223" description="August 6, 2026">
  * Added owner wildcard entries (`"owner/*"`) to the `strictKnownMarketplaces` and `blockedMarketplaces` managed settings for allowing or blocking all marketplace repos under a GitHub org
  * Added a warning when workflow agents, forked skills, slash commands, or resumed background agents' requested subagent model is restricted and the parent model runs instead
  * Added a `/teleport` hint in cloud sessions showing how to continue locally with `claude --teleport <session id>`
  * Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks
  * Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog
  * Fixed workflow scripts being able to use dynamic `import()` to run code outside the workflow sandbox
  * Fixed a permission gap where an agent definition's `bypassPermissions` mode ignored the org bypass-permissions disable policy
  * Fixed resuming a session after a mid-session `/cd` coming back empty
  * Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as `vertex_ai/claude-*` or `bedrock/anthropic.claude-*`
  * Fixed `modelOverrides` keys that aren't Anthropic model IDs being treated as the session's canonical model ID; unknown keys are now ignored as documented
  * Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local `managed-settings.json` or MDM profile; admin env now merges per key
  * Fixed sandboxed commands failing to start on Linux when `sandbox.filesystem.denyWrite` covers the working directory
  * Fixed forked background agents getting stuck "already resuming" for the rest of the session when rebuilding the fork's parent prompt failed during resume
  * Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment
  * Fixed a rare hang when parsing unusual `git push` output
  * Changed `CLAUDE_CODE_DISABLE_1M_CONTEXT` to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn't holding the session to 200K
  * Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set `CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1` to restore the previous behavior
  * Changed `/review` to be an alias of `/code-review`, which reviews the current diff or a PR (`/code-review <level> <pr#>`); use `/code-review ultra` for a deep cloud review
  * Changed `/code-review` with no effort level to reuse the level you typed last; type a level like `/code-review high` to change it
</Update>

<Update label="2.1.222" description="August 4, 2026">
  * Fixed worktree-isolated sessions and their subagents being able to run destructive git commands against the main checkout; isolation now applies to file edits and Bash in every session type
  * Fixed PreToolUse auto-allow hooks bypassing tool restrictions in background agent tasks (summaries, compaction, renames)
  * Fixed `/usage-credits` on Team and Enterprise showing "you've already sent a usage credit request" for members whose earlier request was dismissed, blocking them from sending a new one
  * Fixed the startup connectivity check hanging and then failing behind an HTTPS proxy; it now uses the same proxy-aware transport as API requests and times out with a clear message
  * Fixed "Connection closed mid-response" errors being reported on responses that had actually completed
  * Fixed `/usage` overattributing usage to MCP servers: a server's share now reflects only the requests that actually consumed its tool results, instead of every turn after any call to it
  * Fixed sessions not linking to pull requests created after the branch was pushed, including through the GitHub REST API
  * Fixed org-restricted `model: opus`-style subagent and teammate family aliases dropping to the parent model instead of stepping down to the newest org-allowed model in the family
  * Fixed stream idle timeout firing on custom `ANTHROPIC_BASE_URL` gateways despite server keep-alive pings arriving on the wire
  * Fixed claude.ai connectors being falsely marked as needing authorization when the session token is invalid — they now show a `/login` hint instead
  * Fixed tool errors not being displayed for tools no longer available locally, for example after an MCP server is removed
  * Fixed `SendMessage` rejecting a long summary — it now truncates instead, so sends no longer fail on a character limit
  * Fixed the spinner's effort label in a subagent's transcript view showing the session's effort level instead of the subagent's own `effort:` setting
  * Fixed rare crashes when a file watcher hit a filesystem error or during file-watcher teardown
  * Fixed screen readers re-reading the whole input line on every backspace in `--ax-screen-reader` mode — end-of-line deletions now echo just the deleted characters
  * Fixed host model-selection keys not taking precedence over a stale on-disk `managed-settings.json` when `CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST` is set
  * Improved auto mode safety: messages sent to other agent sessions via `SendMessage` are now evaluated by the permission classifier before dispatch
  * Improved the refusal when Claude tries to invoke a skill with `disable-model-invocation`: Claude is now told to ask you to run the skill instead of replicating its workflow
  * Improved the `/diff` view, the Remote Control workspace diff, and file-edit diffs in Claude Code on the web sessions to use raw git blob content, ignoring workspace-configured diff drivers and textconv
  * Changed Remote Control auto-start so repo-local settings (`.claude/settings.json` or `.claude/settings.local.json`) can no longer turn it on (they can still turn it off); enable it at user scope via `/config`
  * Removed ultraplan feature
</Update>

<Update label="2.1.221" description="August 4, 2026">
  * \[VSCode] Added Focus view: a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator, toggled with `Ctrl+Alt+F` or the "Claude Code: Toggle Focus view" command
  * Added `mode: "mask"` for sandbox credential files on Linux and WSL — sandboxed commands read a sentinel copy (the whole file, or just the spans captured by an `extract` regex) while the sandbox proxy substitutes the real value on egress; on macOS file masking falls back to `deny`
  * Added warnings to `claude plugin validate` when a marketplace or plugin name would be rejected by Claude Desktop's managed marketplace sync
  * Added a `prompt-audit` subcommand to the `claude-api` skill for auditing prompts and tool descriptions for patterns written for older models
  * Fixed a Bash tool permission-check bypass where zsh could execute hidden commands in `[[ ]]` regex conditionals; affected commands now prompt for permission
  * Fixed PowerShell permission checks mishandling paths containing quote characters on Windows; such paths now prompt for approval
  * Fixed the thinking toggle having no effect for the rest of a session that started with thinking off; disabling an MCP server mid-connect no longer silently reverts
  * Fixed MCP servers from `--mcp-config` not being connected before the first turn in print mode (`-p`), which made the model emit tool calls as literal text
  * Fixed @-mentioned files being silently dropped when pressing Esc to retract a prompt and resubmitting it
  * Fixed a crash when preparing API requests for SDK MCP tools named after built-in object properties such as `constructor`
  * Fixed WebSearch failing with a 400 error at effort `xhigh`/`max` when thinking is disabled
  * Fixed sandboxed large uploads failing with TLS errors through the sandbox proxy
  * Fixed Team and Enterprise spend-limit message incorrectly blaming the org's monthly limit instead of your individual spend limit
  * Fixed Bedrock authentication with AWS SSO named profiles failing in desktop-managed sessions on Windows machines that set a stray `HOME` environment variable
  * Fixed `CLAUDE_CODE_RESUME_INTERRUPTED_TURN=0` not disabling interrupted-turn auto-resume; falsy values are now honored
  * Fixed a rare wake-from-sleep race where two Claude Code processes could both refresh the same MCP connector or WIF OAuth token at once, forcing re-authentication
  * Fixed renaming a session from Claude Code Desktop or claude.ai not updating the CLI's session name; session names from every rename surface are now sanitized
  * Fixed plugin- and org-delivered skills named after terminal-only built-ins (e.g. `/help`, `/feedback`) being un-invocable in non-interactive sessions
  * Fixed the "Plugins changed" notification lingering after plugins were reloaded instead of clearing
  * Fixed Vim mode: the yank register now survives dialogs, history search, and the transcript view instead of being silently emptied
  * Fixed Vim mode: undoing back to an empty prompt now arms the "press ← again" confirm before returning to the agent view
  * Improved tool search on Google Vertex AI: re-enabled for Claude 4.5-generation and newer models
  * Improved auto mode: permission checks for parallel tool calls are now cache-efficient, and switching modes while a check is pending reliably prompts instead of applying the stale result
  * Reduced prompt-cache costs for auto-mode permission checks by reusing the cached conversation prefix across decisions
  * Improved Stats panel to count cache tokens in its token totals, with a breakdown by input, output, cache read, and cache write
  * Improved `/ultrareview` error messages when a repo shares no history with its base: a checkout with no branches is now refused up front with advice to create one, and refusal hints no longer suggest `git fetch --unshallow` on clones that are already complete
  * Improved Windows startup: process creation times are now read via a native kernel32 call instead of spawning PowerShell, so endpoint security tools that gate `powershell.exe` no longer prompt
  * Changed background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives
  * Changed `/plugin install` to refresh a stale marketplace catalog and retry before reporting a plugin not found
  * Changed plugins installed from `/plugin` to activate immediately when safe, instead of always requiring `/reload-plugins`
  * Changed plugins to accept `"."` as a `skills` path, and the root-level `SKILL.md` validation error now suggests using the plugin root
  * Changed `/status` to show the session kind: `interactive`, or a background job that is `attached` or `unattended`
  * Changed emoji autocomplete to accept common alternate shortcodes like `:thumbsup:`, `:thumbsdown:`, and `:love:`
  * Changed sessions forked with `/fork` to create a new worktree of their own instead of working in the original session's checkout
  * Changed Claude in Chrome to close the browser tabs it opens once it no longer needs them
  * Changed fast mode to report on the stream when usage credits run out mid-session, instead of failing silently
  * Changed Monitor: a watch that exits without producing any output now says so instead of reporting "stream ended"
  * Changed the Gateway `model` field validation: non-string values are rejected with a 400 instead of being forwarded
  * Removed the repeated "Permission mode changed while the auto-mode classifier call was queued" notice from approval prompts
</Update>

  * Bug fixes and reliability improvements
</Update>

<Update label="2.1.219" description="July 24, 2026">
  * Added Claude Opus 5 (`claude-opus-5`), now the default Opus model — 1M context, fast mode at $10/$50 per Mtok
  * Added `sandbox.network.strictAllowlist` setting to deny non-allowlisted hosts for sandboxed commands without prompting
  * Added `DirectoryAdded` hook that fires after `/add-dir` or the SDK `register_repo_root` control request registers a new working directory mid-session
  * Added `mcp_server_errors` to the headless stream-json init event, listing `--mcp-config` entries skipped by config validation; terminal runs print a startup warning
  * Added the `workflowSizeGuideline` settings key so the advisory Dynamic workflow size guideline can be set from any settings file; the `/config` row is hidden while one does
  * Added nested subagent forwarding in stream-json: subagents spawned at depth-2+ now appear when `--forward-subagent-text` is set, keyed by their spawning Agent `tool_use` id
  * Fixed `claude -p` text output dropping the answer already produced when a turn dies on a mid-stream API error
  * Added HTTP status and error text to `claude mcp list` and `/mcp` when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
  * Fixed the Fable model row showing "Requires usage credits" for plans that include it, when a stale cache had baked the label in
  * Fixed the `/model` picker showing the merged Opus row as plain "Opus" instead of "Opus (1M context)"
  * Fixed copy-on-select inside GNU screen printing base64 into the terminal instead of copying the selection
  * Fixed Remote Control clients keeping a stale fast-mode status after a model switch, reconnect, or failed org check
  * Fixed `CLAUDE_CODE_GIT_BASH_PATH` on Windows exiting or being used as bash when the path isn't a bash/sh binary; it's now ignored with a warning
  * Fixed Vim mode: pressing ← on an empty prompt now returns to the agent view from NORMAL mode, not just INSERT
  * Fixed screen-reader mode rewriting the entire input line on every keystroke instead of echoing only the typed character
  * Improved the "Remote Control is only available via api.anthropic.com" error to name the specific setting that caused it
  * Improved `claude --teleport` to show which repo your current checkout points at when it doesn't match the session's repo
  * Changed dynamic workflows to default to a medium size guideline (aim for fewer than 15 agents); pick another size or unrestricted with Dynamic workflow size in `/config`
  * Changed managed MCP allowlist/denylist `${VAR}` entries to resolve from the startup environment and managed-settings env instead of settings-file env
  * 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
  * Added the current default workflow size to the running-workflow status line, with a pointer to `/config` for changing it
  * Removed Opus 4.7 from fast mode; `/fast` now applies to Opus 5 and Opus 4.8
  * Updated the claude-api skill to default to Claude Opus 5, with a migration path from Opus 4.8
  * Subagents can now spawn nested subagents up to depth 3 by default (was 1); set CLAUDE\_CODE\_MAX\_SUBAGENT\_SPAWN\_DEPTH=1 to disable nesting
