Release Notes
- Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted
- Added the session's additional working directories to MCP roots/list, with notifications/roots/listchanged sent when the set changes
- Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196)
- Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically
- Fixed returning to claude agents silently stopping running subagents and re-running the prompt from scratch — their work now carries over
