Claude Code version 2.1.205 introduces several bug fixes and improvements focused on stability, session management, and security. Key changes include fixing crashes related to deleted directories and file watchers, as well as correcting issues with session-to-PR linking and background agent status.
- Added an auto mode rule that blocks tampering with session transcript files.
- Fixed --json-schema producing unstructured output for invalid schemas or rejecting valid format keywords.
- Improved auto mode to ask before running rm -rf on variables it cannot resolve from context.
- Auto-update binary downloads now stream to disk, cutting the updater's peak memory usage by roughly 400 MB.
- Fixed background tasks in web and mobile Remote Control panels showing stale status by forwarding full task state.
- Reserved the "Claude Browser" MCP server name alongside "Claude Preview" ahead of the Claude Desktop pane rename.
These updates enhance reliability for Windows users and those using background agents, while also improving security by preventing fabricated approvals and reducing memory consumption during updates.
