so i've been on vacation for a while and i've lost track of all the CFWs and stuff

so what i want to know is:
what's the newest CFW for 6.20 and 6.39 (oh and there's a 6.60 now?), like all the different kinda, PRO, ME..etc
and there seems to be two kind of PROs spread around the web, one the original PRO and there's the GodPRO, what's the difference?
