Release Notes
- Added GitLab merge request URL support to the --worktree flag and the claude agents view (where MRs display as !N)
- Added an opt-in forwarduseridentity 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 (CLAUDECODETOOLMEMORYLIMIT) so a runaway build can't stall the session
- Added CLAUDECODEWEBFETCHCACHETTLMS 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 round trips no longer block the agent's launch
- 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
- Improved claude plugin validate to check a bare .claude/skills directory, reporting SKILL.md files whose frontmatter fails to parse
- 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
- Improved print mode diagnostics: a [claude-code:unrecogni
