​New features included in this release: 
1.  The maximum tilt limit the user can specify for firing the sustainer motor has been reduced from 90 degrees to 45 degrees.  This was done because the Mx152 pyro board now has a 45 degree safety limit that cannot be disabled.  If the gyro tilt reading ever exceeds 45 degrees, even momentarily, then sustainer motor firing is permanently disabled for the rest of the flight.   Even if the rocket rotates back into a more vertical orientation.  This was done to improve safety.  Of course the user can still specify a limit less than 45 degrees.

2.  Added "GPS ALTITUDE: USE" to the pyro board deployment settings page in order to clarify that GPS is always used for deployment regardless of the other settings.

3.  The pyro board apogee timer menu page has been updated to better explain that it is used as a backup for GPS deployment at apogee.  It is not a substitute for GPS controlled deployment.

4.  Other minor bug fixes and improvements.

5.  No support yet for AUX or SSR (solid state relay) outputs on the Mx152 pyro board.  Coming soon...
