Counter-Strike: Global Offensive Beta Patch 10 August 2012

The update will be applied automatically when your Steam client is restarted
Valve has issued a new beta patch for Counter-Strike: Global Offensive (CS: GO) updating the bot aiming system. Players should see a substantial decrease in the ability of bots to get perfect shots on moving targets, especially at lower difficulty levels. Bots now can react poorly (or well) to enemies that are dodging/strafing, and also must now account for their own movement while shooting.
