+## [1.12.13] — 2026-06-27
+
+### Changed
+- **Speed column split into Factor + Time**: the old `21.8s · 1.30x` cell is now two separate sortable columns — **Factor** (`1.30x`, audio÷render, colour-coded green/amber/red) and **Time** (`21.8s`, total render time). Column order: Length · Duration · Factor · Time · WPM · Seed · dBFS · Type · Source · Rating · Tags · Note · Active.
