New Plane 3.9.1 stable release


(tridge) #1


The ArduPilot dev team are delighted to announce a new stable plane release. This is a minor release, but does include some important fixes.

Important changes from the 3.9.1beta releases include:

  • updated to default values for some tuning parameters

  • fixed a critical safety issue found by Oliver Volkmann, and fixed by Michael du Breuil. The problem could lead to quadplane motors starting on reboot

  • fixed a bug where RC failsafe could lead rudder input stuck at the last rudder input value in some modes. Thanks to Michael du Breuil for the fix

  • improved DShot and BLHeli-passthrough support, fixing errors reported by BLHeli32 ESCs and making using BLHeliSuite32 much more reliable

  • new tonealarm system, bringing the tones produced under ChibiOS and Linux HALs in line with tones produced under the HAL_PX4 HAL.

  • added a new LED driver for the NCP5623 LED

  • fixed delay caused by parameter writes in AP_Stats

  • fixed default RSSI input pin on some boards

  • fixed the incorrect display of “no io thread heartbeat” message

  • fixed microSD support on some boards due to running out of DMA capable memory

Many thanks to everyone who has been testing the beta releases.

For all support issues with this release, please use the topic in the Plane forum: Plane 3.9.1 stable released

Happy flying!
