This thread is intended to present any known bugs and other issues with the 3.2 stable release. It should not become a general chit-chat thread, nor is it a problem resolution or investigation thread. But if I've missed something, please feel free to post to highlight the issue. Only significant problems which would cause a crash or other dangerous operation will be shown, to keep the list short.
Do not use DO_Set_Home mission command. This results in a bad operation within the program, and definitely lead to a crash. https://github.com/diydrones/ardupilot/issues/1677
Sometimes the Landing Detector has a false positive and will shut down the motors even while flying at altitude. https://github.com/diydrones/ardupilot/issues/1678 This error is very rare, but has happened a few times. The error is recoverable if the user immediately increased the throttle stick position to full, or switches to Stabilize and raises the throttle. The copter will begin flying again.
RCMAP do not use the correct RC_Min and Max values. https://github.com/diydrones/ardupilot/issues/1661
There is a workaround, ensure all your channels have exactly the same Min and Max in your Transmitter, then redo the radio calibration and ESC calibration. Now even though the RC_Min and Max params are not working right, it has no effect as they are all the same anyway.
