Changes I've found so far:
* 1BBA no longer stuns, it knocks back and rings out to your right.
* Pimphand deals 12 damage normal, 14 counter.
* Pimphand knocks back to 66B range.
* 4A knocks back/down and rings out to your right.
* 3AB sends behind you on normal hit and will ring out.
* WR A now has WR A4 draw that does 28 damage vs regular WR A 18.
* I *think* CH4B:B sends them behind you further.
* CH4B:B, BT B+K seems to have changed in timing.
* Guard break/soul crush A+B+K added. Move from SC3, don't know the notation sorry.
* 66A+B4 actually listed in the move list. Forces them into a stun crouch, but doesn't seem that BT B+K will combo into it.
* 3B4, 66A+B4, BT [B+K] combos for 64-67 damage and will ring out in front of you. Yes, only the fully charged BT B+K will work.
* FC 3B, 66A+B4, BT [B+K] combos for 76 damage and front ringout.
Both of those combos can be just ukemied out of after 66A+B4.
