The update offers a number of bug and exploit fixes. Among the changes: fixed damage dealing for the Heavy's Natascha unlockable, updated AutoTeam balancing logic, and players no longer getting stuck in the "prepare to respawn..." countdown. Some of the exploit fixes also apply to Day of Defeat: Source.
