- Removed all of the 328p-related code, which seemed to clean up things quite a bit without all those ifdefs everywhere. - Since the 328p was very memory and flash limited, lots of compile-time options were disabled by default. These have been now been enabled by default. As they are considered generally helpful and does not significantly impact how Grbl runs. - For example, status reports can now report back real time feed rate and line number being executed. Variable spindle is standard with a separate spindle enable pin. Grbl will now check if a user setting has exceeded the maximum step frequency and report an error, if so. And finally, M7 flood coolant is enabled. - In addition, all buffers have been significantly increased to take advantage of the additional memory available. The planner buffer can plan up to 36 motions. The serial buffers have been doubled in size (256/128 bytes RX/TX). And the longest line Grbl can accept is 256 bytes, per the g-code standard (Grbl 328p is limited to 80). - Removed the cpu_map folder, since this version is strictly Mega2560.
