This release improves OAuth security error handling and enhances the resource access state UI for macOS users.

New Features

  • Enhanced Access State UI - The Connect interface now displays a tri-state access status for resources, providing clearer visibility into permission states (available, denied, or unavailable)
  • macOS Permission Remediation - Added an informational banner to guide macOS users through fixing permission denials, making it easier to resolve access issues

Bug Fixes

  • OAuth Error Sanitization - Improved security by properly sanitizing error messages from OAuth callback failures and token endpoint errors, preventing potential information leakage in error responses
