 # Changelog
 
+## 2026-03-15 to 2026-03-22
+
+- Device connectivity and routing: added Android USB serial companion support, serial compass support, GPS module controls, per-contact path size selection, and favourites support via firmware flags.
+- Location and map intelligence: added RSSI-based repeater trilateration and contact location estimates, isolated MET history, matched the official advert import/discovery flow, and refreshed map presentation by removing contact trails.
+- Telemetry and device info: surfaced self telemetry and sensor defaults, opened device info from signal and battery taps, improved signal chip behavior, fixed duplicate telemetry delivery, and restored telemetry refresh behavior.
+- Contacts and messaging: added meshcore:// contact sharing and repeater neighbour views, supported MeshCore message links, fixed DM retry behavior, corrected room poster naming, and compacted the recipient selector.
+- UI polish and platform upkeep: improved device settings layout, tightened sensor and contact presentation, expanded localization coverage, and refreshed platform dependencies and build numbers.
+
+## Key PRs
+
+- [#26](https://github.com/dz0ny/meshcore-sar/pull/26) Merge pull request #26 from `dz0ny/feat/sensor-telemetry-preview`
+
 ## 2026-03-08 to 2026-03-14
 
 - Discovery and contacts: finished the discovery flow, removed artificial UI delays, added profile storage and sync, and allowed contact name overrides.
