Though the World of Warcraft Public Test Realm Patch Notes still list version 2.4.3, Massively reports that a new version 3.0 patch is now live on the World of Warcraft PTR, offering the chance to sample the last major update before the Wrath of the Lich King expansion. Changes include major character class revamps, the new inscription profession, a new area in the city of Stormwind, barbershops in capital cities, and more.
