Release Notes
- 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, filepath, 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 CLAUDECODEATTRIBUTIONHEADER (direct Anthropic API connections)
- Fixed /model rejecting Sonnet/Opus 1M for claude.ai subscribers using a custom ANTHROPICBASEURL gateway
