New: Chess Clock — free for everyone. Pick a preset from Bullet to Classical or set your own time control, with increment or delay and different times per player for coach games.
Puzzles: going back now returns you to the same puzzle, your updated rating shows right after each solve, and the previous puzzle's engine suggestions no longer carry over.
Board themes: choose Classic Brown, Tournament Green or Blue in Profile → Board Theme — it applies to every board in the app.
Also: accuracy now shows correctly (e.g. 91.7%) and the rating chart draws again.
