Updates to Left 4 Dead 2 have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

• Console commands updateaddonpaths and unloadalladdons can't be used while connected to a server.
• Some custom UI's give the ability to change which add-ons are active from the in-game menu. Now those changes won't be applied until the player returns to the lobby or main menu.
• Melee weapon scripts can optionally define the HUD icon data inside the script, similar to other weapons. See golfclub.txt for a format sample.
• Fixed a rare crash in the Spitter attack.
• Fixed a rare crash in bot navigation involving ladders.
