Counter-Strike: Global Offensive Patch 20 April 2012

The update will be applied automatically when your Steam client is restarted
Valve has announced that a new beta patch for Counter-Strike: Global Offensive (CS: GO) is now available via Steam. It reduces the amount of stepwise variation in the weapon recoil patterns so they are smoother and easier to learn and control. Also, the number of seconds to delay showing the player id when crosshairs are hovered over a player has been increased from 0.1 to 0.5.
