New CompassMOT Required After Update?

ArduCopter Copter 3.4

Hi, I just updated my Pixhawk to 3.4.3 and discovered I needed to recalibrate my compass and while the two may or may not be related I have a question:

When performing a minor update are you required to also perform a new CompassMOT and/or any other calibrations?

Thanks!

The best is to read the changelog or the the new release post in this forum. Unless it is stated, it is not usually needed for minor updates, however major releases usually requires to recalibrate the IMU / compasses.

Yes, as @tabascoz stated, read the chnagelog for details on what needs calibrating.

It is probably wise though, if the compass needs recalibrating, then the compass/Mot will need redoing too.

Ah, forgot about the changelog.

Thanks!
