Any thread here about the changes from Ver.A,B,&C

I looked around but couldn't find anything. Is there any information as to the changes? How about character specific changes? I think I remember hearing once that the major overhaul was from A to B.

 

I was told that A to B had no gameplay changes whatsoever, it was just a big overhaul to the way item collection works in the arcades, and stuff like that.

Version C changes are listed in lots of forum threads... I think the easiest way to find them is to go to the character specific dojo forums, where most characters have a thread listing Ver.C stuff.
