Introduced fatigue to the melee attack in versus mode. You will see a HUD display when your melee swing is cooling down



Boomer vomit will now pass through common infected



Addressed some surround sound detection issues



Fixed a rare crash when exiting Left4Dead on Windows Vista



Fixed a case where the complete all expert campaigns achievement was not being rewarded



Corrected an issue where Windows based dedicated were sending spurious shutdown notifications to the master causing them to delist temporarily

Fixed an occasional server crash related to voting
