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:

Mutation
Developer Choice - Last Man On Earth

UI
Added vote option to enable All Talk in Versus.
Added vote option to Restart Chapter in Versus.
Added the ability in the lobby for all players to vote on starting the game.

Gameplay
Removed Defibs and First Aid Kits in Realism Versus. Survivors start with a First Aid Kit, but all world spawns are disabled.

Addons
To avoid conflicts between Community Campaigns, only content vpks get loaded when starting a campaign.
Added console command "show_addon_load_order" that prints out the order of loaded vpk files.

Authoring Tools
VPK files now support their own sound.cache file.
Use the command "snd_buildsoundcachefordirectory " to create the sound.cache file that you should include when you create your vpk file.
