Rover-4.0.0-rc4 (the 4th beta) has been released and is available using Mission Planner or QGC’s “beta firmware” links (or you can manually download the firmware from firmware.ardupilot.org). The changes vs -rc3 are in the release notes and also copied below:

- UBlox F9 GPS automatic configuration
- UAVCAN RTK GPS support
- Bug Fixes:
a) Auxiliary switch support for RTL, SmartRTL fixed
b) Fence health reporting relaxed (was showing Fence Breach when fence was not setup)
c) RangeFinder type parameter clarified for Benewake lidar
d) Barometer PROBE_EXT parameter description improvement
e) Pixhawk4 board LED brightness fix
Hopefully this will be the final release candidate so any testing you can do will be greatly appreciated!
