- New env Wio_Tracker_L2_companion_solo_lvgl_v3 on pioarduino 55.03.312-1;
the 2.0.17 env stays until the new one passes the hardware checklist
- SerialBLEInterface: NimBLE variant (PIN pairing through encrypted,
authenticated characteristic properties; setAccessPermissions is a no-op)
- buzzer: i2s_std driver on IDF 5 (legacy driver kept for 2.0.17)
- ESPNOWRadio: IDF 5 callback signatures
- ui-lvgl: psramBuf() for trail drawing, tile cache, map marks, list rows,
keyboard maps and message metadata; internal heap back to 2.0.17 level
