In preparation for The Burning Crusade, Blizzard released patch 2.0.1 in North America and Europe on December 5th, 2006. The patch introduced some of The Burning Crusade's content prior to the expansion itself — including a revamp of the honor system, skirmish Arena matches, and a new Looking For Group interface.
The expansion was released in standard as well as Collector's Edition packages. The Collector's Edition of The Burning Crusade includes a bonus Behind-The-Scenes DVD, an in-game Netherwhelp pet and many other exclusive extras. Installing the expansion does not break backwards compatibility — players are still able to log on to non-BC accounts using The Burning Crusade client.
