If using bi-directional DShot +and the vehicle is running its motors when 32 bit microsecond time +wraps at 71 minutes (or multiples of 71 minutes) then the bug that is +fixed in this release has an approximately 1 in 3 chance of causing +the motor to stop. + +Note that the time is the time since boot, not the time since arming, +so even vehicles flying for a short time could be vulnerable if they +sit for a long time on the ground before takeoff. + Release 4.3.4 1st March 2023 -----------------------------
