- G92 Coordinate offset support.
- (Beta) Limit switch and homing cycle support.
- Many other bug fixes and efficiency improvements.
*Important note for Atmega 168 users:* Going forward, support for Atmega 168 will be dropped due to its limited memory and speed. However, legacy Grbl v0.51 "in the branch called 'v0_51' is still available for use. *Important note for Atmega 168 users:* Going forward, support for Atmega 168 will be dropped due to its limited memory and speed.
