Download Claude Code 2.1.229

- 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- Fixed one-shot claude plugin commands leaving a stray liveness file that could prevent cleanup of outdated plugin versions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
