New Kailh Choc V2 Switches

Looking for details on the Choc footprint… (and haven’t found a direct answer searching so far)

Is the Choc pcb footprint (pin positions) different from regular Cherry MX keys? (Related - are the pin positions on the Choc the same as the Cherry MX Low Profile key?)

Looks like the center alignment pin is bigger on the Choc V2 vs the V1 - is that the only big difference?
