Enhancements

The first major release version for backpack! Lots of new VRX targets, and a swag of other features and bugfixes...

The ExpressLRS team would like to thank Divimath / HDZero for their support and collaboration on an integration between ExpressLRS, and the HDZero Video Receiver (VRX).

What does the ELRS + HDZero integration provide? Currently, the high level feature set allows a user to:

1. Change the band (R-band, F-band) and channel (1 to 8) that the VRX is receiving on from the VTX Administrator menu within the ELRS LUA,
2. At the same time, change the band and channel that a HDZero VTX is transmitting on, assuming it has been configured to use Smartaudio control, and is connected to a Betaflight FC,
3. Start and stop the DVR recording on a HDZero VRX based on the state of an AUX channel,
4. Delay the start or stop of DVR recording by a configurable timespan, when using the AUX control described in item 3 above.
5. There may be more features introduced in future to further extend this integration.

A note on versioning

The versioning scheme chosen by the ExpressLRS devs is based on the semantic versioning scheme. Where a version is defined as “major.minor.patch” major = major new feature and/or incompatible changes minor = minor features or enhancements and/or new targets patch = bug-fixes
