It's been a little while since Blizzard has released a patch for the beta test of StarCraft II. However this week the developer issues the sixth patch for the beta of their upcoming sci-fi RTS sequel. While most of the previous patches were mostly about unit balancing, this particular patch actually has some gameplay changes and additions. That includes being able to view another player's profile after completing a game and some improvements in 2v2 matchmaking.
Of course there are also some tweaks made to the balance of various units. Also there's been an improvement for pathfinding so units can "properly block ramps and choke points".
