@ -41,3 +41,11 @@ First official release with LoRa support.
### Removed
- LoRa SX1278 library is now a stand alone project and should be cloned separately from this project.
## [1.1.1] - 2022-02-06
### Changed
- Beacons time is now "set time" + random seconds between 0-60. This way the beacons are not send at exactly hole minutes. This also prevents rapid firing of beacons on different channels.
### Added
- Messages from APRS-IS are now also processed and displayed on the web interface.
