The bug does not occur often which is why it has been +such a long time before it was noticed. We would like to thank CUAV +for noticing and reporting the bug! + +This release also has some other changes, some of which are to sync +with the Copter 4.3.6 release (which will go to 4.3.7 with this RC +input bug fix) and some are other bugs found since the 4.3.5 plane +release. + +This release skips the 4.3.6 number to sync with copter. + +The full list of changes is: + + - fixed a fault in the INS batch sampler code if you change the INS_LOG_BAT_CNT parameter without rebooting + - fixed the RC input on IOMCU bug explained above + - fixed a bug in ICE engine control if you do a "delay engine start" mission command while flying + - added MCU voltage monitoring for the H757 microcontroller (eg. CubeOrangePlus) + - servo gimbal mount yaw handling fix (only affects 3-axis servo gimbals) + - PiccoloCAN fix for ESC voltage and current scaling + - Gremsy gimbal fix when attached to autopilot's serial3 (or higher) + - added CubeOrangePlus-bdshot build + - fixed a bug in handling bad UART data in the megasquirt serial EFI driver + - added -g option for configuring with debug symbols without full debug (helped with RCIN bug diagnosis) + - fixed airmode switch for QACRO and QSTABILIZE modes + - fixed a rare memory corruption bug in the STM32H757 + - fixed an EKF3 bug in accel bias calculations + - adjust EKF3 accel bias process noise for greater robustness + - cope with compassmot impacting GSF yaw numerical stability + + +Please test and report any issues! + Release 4.4.0 beta1 -------------------
