This was posted earlier on MMO-Champion, from the PTR:
2.3 Rogue Mace Specialization change
Live: Increase your skill with Maces by 2, and gives you a 1% chance to stun your target for 3 seconds with a mace. (Per point)
PTR: Increases the damage dealt by your critical strikes with maces by 1%, and gives you a 1% chance to stun your target for 3 seconds with a mace. (Per point)
