Mar 1, 2025March 2025 (nttcom/threatconnectome) delivered high-impact UI, API, and code-quality improvements that strengthen reliability, security, and admin workflows. Key outcomes include a robust user-management API with a new deletion endpoint, the /me endpoint, and tests ensuring safe cascade deletion; extensive UI/UX enhancements (CloseIcon, delete confirmation dialogs, PropTypes validation) with improved dependency handling; and substantial frontend/backend cleanup and performance optimizations. PTeam permissions enhancements (pteam deletions persistence, renaming pteam_role to pteam_roles, and documentation of invitations) plus endpoint modernization (/users to /users/me) further strengthen data integrity and developer experience. These changes reduce risk of unintended actions, accelerate operations, and improve maintainability and test coverage.
