## What's changed
- 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- Fixed one-shot `claude plugin` commands leaving a stray liveness file that could prevent cleanup of outdated plugin versions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
