Looking through the information from the PTRs, a couple of things leapt out at me:
New achievement: Brew of the Month - Join the Brew of the Month Club - Required for Brewmaster.
A lot (20+) of cooking recipes have been changed to allow players to skill up to 450 with them.
What this means is that it won't take Andro until October 2010 to complete her brewmaster achievement, and she might finally get that last point of cooking ...
(The full list of changes can me found at MMO Champion.)
