Valve has issued a patch for Left 4 Dead 2 and the L4D2 SDK, with map fixes, PZ bots enabling, and other goodies.

VAC users can now play single-player, and folks can no longer quit before they're kicked out in voting.

Here's the list of changes (thanks, Blue):

Gameplay

Now ghost PZ's can never be staggered
Enabled PZ bots
PZ bots use their more aggressive survival mode behavior in versus and scavenge
Enabled finale manual spawn by default
Fixed human PZ players not getting counted when they were dead, allowing extra PZ bots to spawn
Reduced effectiveness of melee weapons against the Tank ( 5% of max health, from 10% )
Fixed a case where a player who dies, then is rescued from a rescue closet, and then is revived from a ledge hang receives the secondary weapon that he lost when he was initially killed
Improved SurvivorBot AI in cases where the bots refused to shoot through their teammates and became non-responsive
Fixed issue with witch sometimes taking on uncommon common properties
Fix for cheaters quitting before the vote to kick them would succeed and avoiding ban on server
VAC banned users can now play L4D2 single-player, commentary mode and credits

Map Fixes

Dark Carnival Fair Ground: added env_player_blocker to keep special infected from getting stuck
Dark Carnival Fair Ground: added navigation area that was missing
Dark Carnival Fair Ground: Disconnected drops that were blocked by the top of a fence
Swamp Fever Plank Country: Deleted 2 nav areas that connected between tree trunks you can't pass through
