# Lappy v0.5.3

Track Session now labels the current course PB consistently in both Classic and Race. Completed rows compare against the same current PB, including recordings saved by earlier firmware. A historical PB event no longer leaves a slower run marked as the current best, and an improvement delta no longer hides the current PB badge.

Live progress comparisons retain the reference captured for the active attempt. Saved elapsed times, sectors, PBs, reference traces, historical event flags/deltas and file formats retain their existing meaning. No recording migration is required.

Guanlan regression: RUN 2 at 1:00.90 is PB; RUN 1 shows +35.34 and RUN 3 +37.86. The update preserves settings and SD recordings.
