9<Update label="2.1.233" description="August 14, 2026">
10 * Added GitLab merge request URL support to the `--worktree` flag and the `claude agents` view (where MRs display as `!N`)
11 * Added an opt-in `forward_user_identity` apps gateway setting on Anthropic upstreams that sends the signed-in user's identity as headers, so a proxy behind the gateway can attribute spend per user
12 * Added opt-in memory cgroup support for Bash tool commands on Linux (`CLAUDE_CODE_TOOL_MEMORY_LIMIT`) so a runaway build can't stall the session
13 * Added `CLAUDE_CODE_WEBFETCH_CACHE_TTL_MS` environment variable to configure the WebFetch session URL cache TTL (default unchanged: 15 minutes)
14 * Fixed cloud sessions occasionally being marked as lost when the environment shut down while Claude was waiting on a permission prompt
15 * Fixed MCP v2 connections endlessly reopening the subscriptions/listen stream against servers that terminate long-held streams on a fixed timeout (e.g. serverless hosts)
16 * Fixed Notification hooks not firing for permission prompts when running under Claude Desktop or VS Code
17 * Fixed idle sessions on Linux sometimes keeping one CPU core at 100% when sandboxing is enabled
18 * Fixed bundled skill aliases like `/checkup` and `/review` reporting "Unknown command" in `-p` mode or with plugins/MCP loaded when a user or project skill shadows the bundled skill
19 * Fixed skill/command argument substitution to prevent argument values from being re-expanded as template markers
20 * Fixed Windows paths spelled with the NT `\??\` device prefix bypassing UNC path validation, closing an NTLM credential-leak vector
21 * Improved `claude self-hosted-runner` session start time: the session branch is now created without rewriting the working tree, and two server round trips no longer block the agent's launch
22 * Improved apps gateway error forwarding: 400/413 errors from Vertex, Foundry, and Claude Platform on AWS upstreams now carry the upstream's own message; fixes a bug with auto-compact on apps gateway
23 * Improved `claude plugin validate` to check a bare `.claude/skills` directory, reporting SKILL.md files whose frontmatter fails to parse
24 * Improved screen reader mode: the `/effort` selector renders as a numbered list with a typed-number prompt, and hint and dialog text is no longer clipped
25 * Improved print mode diagnostics: a `[claude-code:unrecognized_model]` line is written to stderr when a request goes out for a model ID Claude Code doesn't recognize; map it with `modelOverrides` to silence
26 * Changed the GitHub app setup tip to no longer appear in repositories whose origin remote is on gitlab.com or bitbucket.org; the enterprise marketplace tip now covers non-GitHub internal git hosts
27 * Todo/task-tracking tools (TaskCreate/Get/Update/List, TodoWrite) are no longer available on Opus 4.8, Sonnet 5, Fable 5, Mythos 5, and newer models; set `CLAUDE_CODE_ENABLE_TODO_TOOLS=1` to bring them back
28 * Windows: fixed auto mode repeatedly stopping for manual approval on ordinary `cd <dir> && <command> > file` Bash commands (a 2.1.232 regression)
29 * Reverted the 2.1.232 Bash permission changes for Cygwin-style symlinks on Windows and for input redirections (`< file`); a narrower version will return in a later release

1033 * 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
1134 * Type `@` in the prompt to mention another Claude session by name; Claude then uses `SendMessage` to reach that session directly
from line 2201
21782201 * `/terminal-setup` now enables iTerm2's "Applications in terminal may access clipboard" setting so `/copy` works, including from tmux
21792202 * MCP servers that hit a transient error during startup now auto-retry up to 3 times instead of staying disconnected
21802203 * The terminal tab session title is now generated in your configured `language` setting
2181 * Claude.ai connectors with the same upstream URL are now deduplicated instead of appearing as duplicates
2182 * Vertex AI: support X.509 certificate-based Workload Identity Federation (mTLS ADC)
2183 * Faster startup after upgrading: removed the Recent Activity panel from the release-notes splash
2184 * LSP diagnostic summaries now expand on click/ctrl+o and show the expand hint
2185 * SDK: `mcp_authenticate` now supports `redirectUri` for custom scheme completion and claude.ai connectors
2186 * OpenTelemetry: added `stop_reason`, `gen_ai.response.finish_reasons`, and `user_system_prompt` (gated behind `OTEL_LOG_USER_PROMPTS`) to LLM request spans
2187 * \[VSCode] Voice dictation now respects the `accessibility.voice.speechLanguage` setting when no Claude Code language is configured
2188 * \[VSCode] `/context` now opens a native token usage dialog
2189 * Fixed unbounded memory growth (multi-GB RSS) when processing many images in a session
2190 * Fixed `/usage` leaking up to \~2GB of memory on machines with large transcript histories
2191 * Fixed memory leak when long-running tools fail to emit a clear progress event
2192 * Fixed Bash tool becoming permanently unusable when the directory Claude was started in is deleted or moved mid-session
2193 * Fixed `--resume` crashing on startup in external builds
2194 * Fixed `--resume` failing on large sessions when a transcript line was corrupted by an unclean shutdown — the corrupt line is now skipped
2195 * Fixed `thinking.type.enabled is not supported` error when using Bedrock application inference profile ARNs
2196 * Fixed Microsoft 365 MCP OAuth failing with duplicate or unsupported `prompt` parameter
2197 * Fixed scrollback duplication when pressing Ctrl+L or triggering a redraw in non-fullscreen mode on tmux, GNOME Terminal, Windows Terminal, and Konsole
2198 * Fixed claude.ai MCP connectors silently disappearing when the connector-list fetch hits a transient auth error at startup
2199 * Fixed "Always allow" rules for built-in tools in remote sessions not surviving worker restarts
2200 * Fixed `NO_PROXY` not being respected for all HTTP clients when set via `managed-settings.json` under the native build
2201 * Fixed managed settings approval prompt exiting the session even when accepted — now applies settings and continues
2202 * Fixed `/usage` returning "rate limited" after a stale OAuth token — now refreshes automatically
2203 * Fixed invalid legacy enum values in `settings.json` invalidating the entire settings file
2204 * Fixed `/usage` dialog content being clipped when no-flicker mode is off
2205 * Fixed `/focus` showing "Unknown command" when the fullscreen renderer is off — now explains how to enable it
2206 * Fixed embedded grep/find/rg shell wrappers failing when the running binary is deleted mid-session — now falls back to installed tools
2207 * Reduced peak file descriptor usage during `find` in the Bash tool on large directory trees

2210<Update label="2.1.120" description="April 28, 2026">
2211 * Windows: Git for Windows (Git Bash) is no longer required — when absent, Claude Code uses PowerShell as the shell tool
2212 * Added `claude ultrareview [target]` subcommand to run `/ultrareview` non-interactively from CI or scripts — prints findings to stdout (`--json` for raw output) and exits 0 on completion or 1 on failure
2213 * Skills
2204 * Claude.a
