- Auto-mode classification for all shell commands
A new `autoMode.classifyAllShell` setting is introduced to route all Bash and PowerShell commands through the auto-mode classifier, enhancing security beyond arbitrary-code-execution patterns.
- Auto-mode denial reasons and response logging
Auto-mode denial reasons are now available in the transcript, denial toast, and `/permissions` recent denials. A new `claude_code.assistant_response` OpenTelemetry log event provides the model's response text, configurable via `OTEL_LOG_ASSISTANT_RESPONSES`.
- Live file path autocomplete and startup notices
Live file path autocomplete is now available for bash mode (`!`). A startup notice is displayed when MCP servers require authentication, directing users to `/mcp`.
Enhancements (1) ›
- Automatic memory-pressure reaping for idle background shells
Idle background shell commands will now be automatically reaped due to memory pressure. This behavior can be disabled by setting `CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP=1`.
Fixes (2) ›
- Fixed stale UI state after login and background task cancellations
Issues with `/model` and other client-data-gated UI components showing stale or empty states immediately after `/login` have been resolved. Spurrious cancellations of background tasks with "N background tasks would be abandoned" messages have also been fixed.
- Resolved phantom sub-agent creation and agent panel issues
A phantom "general-purpose (resumed)" sub-agent that incorrectly re-ran the main conversation when backgrounding the main turn has been fixed. Issues with the agent panel hiding sibling agents when viewing a subagent are also resolved.
