Claude Code v2.1.233 adds GitLab MR support, user identity forwarding, memory limits for Bash tools, and fixes several bugs, while also removing some todo/task tools from newer models by default.

READY TO POST:

claude code just dropped v2.1.233! gitlab merge request support is in for --worktree and agent views. also, better user identity forwarding for spend attribution.

new claude code update means linux users can now set memory limits for bash tools, preventing runaway builds. heads up: todo tools are off by default on opus 4.8+ and other new models, but you can re-enable them.

[MERGED across 2 sources: github_releases, pages] shared signal: claude-code --- github_releases :: anthropics/claude-code --- anthropics/claude-code release: v2.1.233 name: v2.1.233 published: 2026-08-14T22:20:57Z url: https://github.com/anthropics/claude-code/releases/tag/v2.1.233 ## What's changed - Added GitLab merge request URL support to the `--worktree` flag and the `claude agents` view (where MRs display as `!N`) - 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 - 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 - Added `CLAUDE_CODE_WEBFETCH_CACHE_TTL_MS` environment variable to configure the WebFetch session URL cache TTL (default unchanged: 15 minutes) - Fixed cloud sessions occasionally being marked as lost when the environment shut down while Claude was waiting on a permission prompt - 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) - Fixed Notification hooks not firing for permission prompts when running under Claude Desktop or VS Code - Fixed idle sessions on Linux sometimes keeping one CPU core at 100% when sandboxing is enabled - 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 - Fixed skill/command argument substitution to prevent argument values from being re-expanded as template markers - Fixed Windows paths spelled with the NT `\??\` device prefix bypassing UNC path validation, closing an NTLM credential-leak vector - Improved `claude self-hosted-runner` session start time: the session branch is now created without rewriting the working tree, and two server
