Notes for World of Warcraft patch 6.1 have reportedly leaked online, and they include a number of unexpected additions to the game.

The notes were reportedly leaked as the patch was being deployed on the public test realm.

According to the patch notes, the patch will add a number of anti-aliasing options to the game, including MSAA, SSAA+ and CMAA, and Nvidia’s HBAO.

Twitter integration has also reportedly been added. The system will allow players to tweet from in-game, and can be configured to automatically tweet on special occasions, for example, when a boss is killed, or when a new piece of epic loot is obtained. A screenshot can also be attached.

A full list of the rumoured changes can be found on MMO Champion.
