0.3.0-alpha307.09.2026 · Stable location and RuStore updates
- The main map uses one most reliable location provider so a precise GPS fix is not replaced by a coarse network position
- Inaccurate, outdated, and sharply degraded fixes are rejected while the last reliable position remains visible when signal is lost
- The last reliable position is stored locally and reused instead of an offline-map centre or a default point when the map is reopened
- RuStore installations open updates in RuStore and never offer a website APK sideload
- Installations from ths2.app retain secure APK downloads with package, version, signature, and checksum verification
