New features

 * New achievements for Broken Steel

Bug fixes

 * Fixed issue with V.A.T.S. calculations not appearing properly for perks (PC)
 * Fixed crash related to altered references between master files
 * LOD objects render properly when loaded from DLC worldspaces
 * Fixed issue with companion NPCs not loading into cells immediately after player
 * Fixed the issue with the door in Vault 87 where Colonel Autumn came through.

 * New bugs introduced, check discussion page

Bugs

 * Playing with mods that place new objects in the game may cause the game to crash. (This is fixed by converting the .esp files into a .esm through an application like Fallout Mod Manager)
 * Saving the game with mods may cause the game to crash. (This too is fixed through the manner stated above)
 * Playing a stock installation of the game with this patch installed may cause the game to crash after 1 to 5 minutes.
 * It appears that when the player (or an NPC) opens a door or cabinet, closes it and then opens it again, it will make a double sound. It can be especially annoying when opening a vault door.
 * It appears that many users experience freezing when attempting to exit the game.
 * Operation Anchorage may fail to start for certain users.
 * After selecting targets in V.A.T.S. the game may freeze.
 * In some reported cases, none of the intentional changes (as listed at the top of this page) occurred, and the patch was therefore useless to said users.
