Blizzard has rolled its latest content update out across US World of Warcraft servers. Its European counterparts will follow soon.
Patch 2.3 brings with it a whole host of goodies, including a new dungeon called Zul'Aman; guild banks; faster levelling from 1-60; fresh Honour, Badge of Justice and gladiator rewards; and schematics for Engineers to build their own flying mounts.
There are also lots of fixes and tweaks to absorb, including the usual class, item and world fiddles. Better pop over to the official site for those, because it will take me all day to describe them.
