The World of Warcraft: Burning Crusade patch 2.1.1 has been released.  Here are the patch notes:

BUGS

  • Players will now be able to properly destroy the infernals in the quest “The Fel and the Furious”.
  • Gladiator’s Plate Legguards: Fixed a graphical display error.
  • Fixed a bug that caused some systems to see terrain holes appear in the distance.
  • Stackable items retrieved from mail will no longer automatically stack in your inventory.  This has been disabled pending a future patch fix.
  • Players will no longer see the flickering terrain issues that were introduced with 2.1.0 when the LOD system is enabled.
