November 2025 Highlights for IT-Academy-BCN challenges: Delivered UX improvements and backend refactors that increased data freshness, UI stability, and maintainability. Frontend delivered auto-refresh of the challenge list after creation, a collapsible and streamlined filters UI with an All option, and UI/layout fixes that enhance responsiveness and accessibility. Implemented and then aligned progress filtering with status semantics, and completed release/documentation work across 3.11.x and 3.12.0-RELEASE. Backend introduced a consolidated InteractionDocument base class for user interactions, and improved test coverage for BookmarkDocument and FavoriteDocument. Extensive test cleanup, linting removal, and regression tests further improved quality. These changes reduce time-to-value for features and decrease risk in future releases.
