- Homing cycle failure reports alarm feedback when the homing cycle is exited via a reset, interrupted by a safety door switch, or does not find the limit switch. - Homing cycle bug fix when not finding the limit switch. It would just idle before, but now will exit with an alarm. - Licensing update. Corrected licensing according to lawyer recommendations. Removed references to other Grbl versions.
