It wasn't a major tweak or anything~ I think they just changed the girl's bust a little bit and got rid of the old eye option.. but I think it made quite the difference. xD
found the DA page explaining it. There's a link to the old base in there too.

I think I notice the change way more cause half of my friends list is inactive. o.o Don't worry! I don't mean to make you freak out or anything, these are just my observations. ;_;
