Kevin Knocke from Blizzard details the new multi-player patch for Starcraft II: Heart of the Swarm. The patch is releasing very soon, and adds some great functionality to custom interfaces and observer modes. Please note that because of the nature of the patch any replay video saved before the patch will have to be viewed in the older versions of the game. Patch notes will be detailed here and any updates of course will be found at that link as well.
