This release focuses on bug fixes and reliability improvements, particularly around configuration handling, text encoding, and server imports.

Bug Fixes

  • Configuration management: Fixed an issue where not all server configuration fields were properly copied during config operations, which could lead to incomplete server settings
  • Text handling: Resolved UTF-8 encoding errors in direct-mode by ensuring text truncation occurs at valid character boundaries instead of mid-character
  • Server imports: Fixed conflict resolution when importing servers with duplicate names, ensuring the conflict-rename mapping works correctly with both original and sanitized server names
  • Release process: Improved reliability of the code-signing retry mechanism with corrected artifact patterns

New Features

  • Audit logging (Teams edition): Added per-user audit records for credential brokering operations, providing detailed tracking of credential access and usage for compliance and security monitoring (MCP Spec 074 T10)
