Rover-4.2.0-rc4 is available for beta testing and can be installed using MP or QGC’s beta firmwares links or it can be directly downloaded from firmware.ardupilot.org.
The changes vs -rc3 are in the release-notes and also copied below
- FlyingMoon F407 and F427 autopilots supported
- Bug fixes
a) Log file list with over 500 logs fixed
b) RSSI when using IOMCU pin 103 fixed
As you can see this is a very minor release to resolve a couple of regressions that turned up. If we’re lucky then this will be the last release candidate before 4.2.0 is released as the stable version.
Thanks in advance for any testing results either positive or negative!
