Apr 1, 2025April 2025 for microsoft/json-schemas focused on stabilizing release processes, modernizing schemas, and cleaning code while reducing UI maintenance. Key outcomes include release tagging automation for the April PP cycle, a major JSON Schemas overhaul with improved structure and validation rules, and targeted code quality cleanups to improve readability and maintainability. UI cleanup removed the localization context menu to simplify the interface. ActivityIcon description improvements were implemented to clarify usage, and unintended changes were reverted to restore prior behavior, reducing risk. These efforts collectively improved release traceability, validation accuracy, and code health, enabling faster, safer iterations.
