Latest documented release · 0.8.1
Smoother track recovery. Clearer recording diagnostics.
Refines off-course detection, automatically starts the next circuit lap after recovery, and improves route recording diagnostics. Existing course identities, PBs and reference traces are retained. Browser update/recovery passed on macOS + Chrome; Windows and Edge remain unverified.
In this release
- Off-course detection. Uses a 20 m default corridor and confirms a continuous excursion for at least one second of both GPS and arrival time.
- Next-lap recovery. After an invalid circuit lap, good continuity and a fresh forward start/finish crossing start the next lap automatically.
- Route recording. Confirmed movement can reconnect within 10 m of the last trusted position after a stationary hold; larger unexplained jumps remain blocked.
- Recording diagnostics. JSON and VBO distinguish sample gaps, quality pauses, clock changes, position jumps and route breaks.
- Saved data. Existing route geometry, identities, PBs and references keep their formats.
- Validation scope. Recorded and synthetic replay tests passed; complete field laps and browser USB acceptance remain separate checks.
