+## [1.12.9] — 2026-06-27
+
+### Changed
+- **Benchmark speed factor shows 2 decimal places** (`1.32×` instead of `1.3×`) in the SPEED column and live status line — more precise RTF comparison across voices.
+- **Sorting by Speed now sorts by the RTF factor** (faster voices first) instead of by raw synthesis time — voices with a higher `×` multiplier rank higher regardless of how long the benchmark sentence was.
