Jun 1, 2025June 2025 monthly summary for instructure/canvas-lms focused on reliability, localization, and user feedback improvements. Deliverables include a feature enhancement (Tag-Based Assignment Visibility) and several critical bug fixes that enhance correctness and user experience: - Feature delivered: Tag-Based Assignment Visibility, with updated module queries and tests to restrict visibility to students with matching tags. - Bugs fixed: Auto Peer Review Scheduling Guard (Touch Events) to prevent scheduling do_auto_peer_review when touched; Locale-Aware Section Date Saving to ensure correct 24-hour format across locales with tests and utilities refactor; Clear Deleted Discussion UX Message to display a dedicated 'This Discussion has been deleted' message instead of a generic error. Overall impact: Reduced scheduling errors, improved date handling across locales, clearer feedback for deleted discussions, and finer-grained access control for assignments. These changes contribute to more reliable workflows, better localization support, and improved end-user experience. Technologies/skills demonstrated: backend Rails/Ruby changes, SQL/query updates, test-driven development with added tests, utilities refactor for date/time validation, localization considerations, and UX/message clarity enhancements.
