- support visual odometry quality metric and added autoswitching lua script
- allow for expansion of fence storage to microSD for larger pologon fences
- allow FTP upload of fence and rally points
- fixed vehicle type of ship simulation for ship landing
- make severity level depend on generator error level in IE 2400 generator

- fixed discrimination between GHST and CRSF protocols
- fixed bug in DroneCAN packet parsing for corrupt packets that could cause a crash
- fixed handling of network sockets in scripting when used after close
- fixed bit timing of CANFD buses
New Autopilots supported
- YJUAV_A6Ultra

Other changes

In terms of when will the 4.5.0 stable version be released, because we are releasing Plane, Copter, Rover and Tracker all together, it will depend upon how quickly we can overcome a few outstanding issues but in any case there will certainly be at least one more beta.
All testing and feedback is greatly appreciated!
