The StarCraft II Website announces that a new version 1.5.4 patch is now automatically available for StarCraft II: Wings of Liberty, Blizzard's real-time strategy sequel. This is moot at this very moment, as Battle.net is down for scheduled maintenance (perhaps the installation of this very patch), but in the meantime, players can read about changes the new version brings. Here are the patch 1.5.3 notes, and here's an overview:
