# Software Release Notes

## Intro

ALTA QGroundControl is based on the public version of the [QGroundControl](http://qgroundcontrol.com) and is tailored for use with ALTA X and ALTA 8 Pro. Although you should be able to use the public version, we highly recommend using the Freefly version to be fully compatible. Freefly only uses and tests the ALTA QGroundControl.
