There was a Call of Duty 4 update released yesterday, and all you have to do to get it is restart steam. Now, on to the updates!
- Fixed a case in which un-pure players were able to play on pure servers
- Set properties so that Anti-lag is always switched to "on" once a map loads
- Fixed an issue with sniper rifle accuracy at certain distances
- Text chat between rounds of multiplayer will no longer cut out at the end
