The 2.3 PTR was updated again today, which is very strange, Saturday isn't typically a day that Blizzard patches the PTR, so maybe they're in a hurry to get it to live servers so they can move on to testing 2.4. The most immediate change seen today is the Season 3 Ret Paladin set changes (Scaled Plate). All of the Ignore Armor and Spell Damage effects were removed, and those points allocated to Strength instead, as you can see in the image below.
Update: The PvP trinkets added to the Badge of Justice vendor have also been added to the vendor that sells belts/boots/bracers/rings/necklaces in the honor barracks.

Zul'Aman Event Improved
The Zul'Aman starting event has been improved so that it's similar to a summoning stone. The difference is, as the screenshot shows, 5 players are required to participate in the channeling to open the gates.
