That is the patch notes for WW. Most of it is cosmetic or sound fix. The first one was a bug/ exploit... Which is I'm pretty sure the OP is talking about.
When you're in WW form your skill passives from your out of WW form bars should not have ever been able to work. However, some players found out that if they respec while in WW form, any passive effects in their backbar (non werewolf form bar) would glitch out and activate when they shouldn't. This was not intended and thus was NOT a nerf...
