This firmware is compatible with all OSD/Autopilot/GroundStation boards (this same compatibility as firmware version 2.50).

At any time user may flash this version to his devices and then  after tests flash back previous stable 2.50/2.50a  version  (available on www/pitlab.com webpage) without loosing any existing settings.

Although new version will keep all existing settings, for safety reason we recommend to make settings backup for all devices  before upgrading firmware to version 2.52.
