 - Head includes the following changes.
 
+  - Fix `-Wunused-parameter` warnings from gcc. ([#196](https://github.com/mcci-catena/arduino-lorawan/issues/196)). This is v0.9.2-pre3.
   - Apply pre-release version to `library.properties` and `library.json` ([#195](https://github.com/mcci-catena/arduino-lorawan/issues/195)). This is v0.9.2-pre2.
   - Correct error, missing `return true` at end of `Arduino_LoRaWAN::ApplySessionState()`. ([#194])(https://github.com/mcci-catena/arduino-lorawan/issues/194)).
   - Correct error in logging, missing `return true` in `Arduino_LoRaWAN::cEventLog::processSingleEvent()` ([#191](https://github.com/mcci-catena/arduino-lorawan/issues/191)). This is v0.9.2-pre1.
