Claude Code version 2.1.196 introduces organization default models, clickable file attachments, and improved security for MCP server approvals. The update also enhances background session reliability, fixes various agent status reporting issues, and optimizes token usage in code review workflows.
- Added support for organization default models visible as "Org default" or "Role default" in the model selector.
- Security updates prevent untrusted workspaces from spawning MCP servers without explicit approval.
- Improved background session reliability allows long-running commands to survive process restarts, including on Windows.
- The /code-review workflow now merges five cleanup finders into one, reducing token usage by approximately 25%.
- Fixed issues with PowerShell command reporting, duplicate recap lines, and voice dictation swallowing spaces.
- Added a streaming idle watchdog that aborts and retries streams producing no events for 5 minutes.
These changes improve the stability of background agents, enhance security controls for external servers, and reduce operational costs through optimized token consumption.
