## Version history (last 5 releases)

### v3.2.1 — 2026-08-09

CLASS progression, reworked
One bad session no longer sends your CLASS tumbling. Even on an off day, you can win it back on your next play.
Note: CLASS is recalculated from your history with this update, so where you sit may shift.

Scoring, fine-tuned
How you build an arrangement comes down to preference. We narrowed the score gap between bull finishes, favourite double finishes and favourite triple finishes, so no single way of closing is rewarded disproportionately.

A fuller BGM
Harmony lines now sit under the melody for added depth. The transition into EXTRA GROOVE flows more naturally too.

MY PLAY STYLE, more accurate
Your diagnosis now reflects the tendencies across a whole session, rather than leaning on a handful of moments.

ON THE MIC
Call judging is gentler, so you can practise without pressure.

Also
- Your app version is now shown in Settings
- The privacy policy can be read inside the app

### v3.2.0 — 2026-07-16

Version 3.2.0
MY PLAY STYLE, reworked
A full rework of the style diagnosis, driven by your actual play data. Seven distinct types each for SOFT and STEEL put your habits into words like never before.
Sharing, improved
Share pages got a matching refresh — new design and copy that show off your reworked MY PLAY STYLE.
Introducing ON THE MIC (STEEL only)
A brand-new mode: step up as the caller for a leg of 501. Speech recognition judges your calls while a groove soundtrack keeps you in the pocket.
