This release resolves critical OAuth authentication issues that could cause connection failures, UI freezes, and stale status displays.
Bug Fixes
- Fixed deadlock during OAuth credential persistence - Resolved a deadlock in
persistDCRCredentialsthat could hang the Connect operation - Prevented Connect() from blocking critical operations - Connect no longer blocks Disconnect or HTTP server startup, improving application responsiveness
- Fixed stale "Connecting..." status - Corrected lock ordering in the reconcile process to ensure status updates properly reflect connection state
- Resolved stale state view and improved error handling - Fixed OAuth state view inconsistencies and now properly handle server 5xx responses as token errors
- Preserved DCR credentials during token saves - OAuth DCR credentials are now maintained when mcp-go saves access tokens, preventing authentication failures
- Protected valid legacy tokens from cleanup - Orphan cleanup process no longer incorrectly deletes legitimate legacy tokens
