The update will be applied automatically when your Steam client is restarted
Valve also issued a new patch for Counter-Strike: Global Offensive (CS: GO) resurrecting SourceTV as 'GOTV.' and adding free camera to spectator mode cycle. In addition, it adds a map overview that displays players, events, grenade detonations, etc. Can be drawn on in a select-able colored pen when spectating or if the "sv_competitive_official_5v5" convar is set to 1 on the server or if the client convar "mapoverview_allow_client_draw" is set on the client (drawings are not currently networked to other players).
