Dec 1, 2024December 2024 performance summary for mozilla/kitsune: Delivered a set of backend and frontend improvements focused on moderation, data quality, and UX, driving higher moderation accuracy, better data integrity, and smoother user experiences. Key backend work enhances security and auditability in moderation, including role-based access, explicit moderation timestamps, and safeguards against edits post-moderation, plus robust duplicate handling and context preservation in moderation workflows. Data quality improvements strengthen product tagging and filtering by enforcing active tags, tying product visibility to active AAQ configurations, and improving topic navigation. Slug history management now preserves data integrity when topics evolve, especially with slug reuse. Frontend gains with Alpine.js and HTMX added interactivity, followed by a controlled rollback and final reapplication with cleanup. Revision list UX was improved by persisting filters across sessions and decoupling pagination from session storage. Overall, these changes reduce risk, improve discovery, and enable faster, more reliable moderation and product discovery.
