Recalibrating sensors when updating to 3.4?

I am flying 3.3 since a while. Is it recommended to recalibrate the sensors after updating to 3.4 or are those values safed elswhere and stored?
(I was flying Px4 nativ firmware before and there it was not neccessary, therefore I ask).

Best wishes,

The sensor calibration between 3.3 and 3.4 is compatible, although you can improve things by using the new on-board compass calibration (if your GCS supports launching it)

Thanks Tridge, appreciated. So I will recalibrate.
