New
- The course catalog now covers 30 CS courses, with database, operating systems, and data-structure quiz authoring filled out in tracked batches.
Changed
- Classroom and quiz media gained reusable crop controls so cover and branding images can be framed before upload.
Fixed
- Ranked ELO finalization, abandonment handling, leaderboard visibility, and match-found notifications were hardened around server-authoritative writes.
Why it matters
- Educators need live controls and reusable artifacts that make classroom progress visible without making the room noisy.
