This release focuses on Docker isolation improvements, environment handling for macOS GUI users, and security scan UI reliability fixes.

New Features

  • Environment Variable Forwarding (Teams): New opt-in configuration to forward proxy environment variables to upstream MCP servers for controlled network access (MCP-2769)
  • macOS Login Shell Support (Personal): GUI app now hydrates login-shell environment once at startup, ensuring consistent environment variables when launched via launchd (MCP-2751)
  • Enhanced Telemetry: Added tracking for Docker isolation flag, CLI source identification, and Docker failure codes (schema v5)

Bug Fixes

  • Security Scan UI (Teams): Fixed issue where security scan interface remained stuck on "Scanning…" despite backend job completion (MCP-2740)
  • Scan Cancellation Handling (Teams): Cancelled security scans are now properly treated as non-success states in finalization logic (MCP-2755)
  • Docker Binary Resolution: Improved Docker binary resolution for isolated spawn processes, preventing execution failures in containerized environments (MCP-2753)
  • Docker Path Caching: Fixed stat-probe logic to correctly override negative cache entries in Docker path resolution, improving reliability when Docker becomes available after initial checks
