Copter-3.6.7-rc1 released for beta testing

Hi Roman,

It’s on the to-do list but we haven’t gotten to it yet. I’ll try and bump up the priority on that.

By the way, it shouldn’t be necessary to re-do the compass calibration unless some equipment on the vehicle has been moved around which could affect the magnetic field. ArduPilot includes a small database that holds the declination (the difference between true north and magnetic north) values for anywhere on Earth and the EKF detects the “inclination” soon after startup. So there’s generally no need to re-do the compass calibration.
