Another week, another patch. Tonight, the good guys over at Valve have declared that they have finally implemented a much-missed and much desired feature from WarCraft III DotA: the Swap Hero function.

While the highlight of the patch is obviously the Swap ability - which cannot be used in Single Draft mode - other improvements have been made to the broadcasting and spectating experience in the Dota 2 game client and the user interface, among the usual array of bug fixes.

HIGHLIGHTS:
Added Swap Hero. This cannot be used after creeps spawn or in SD. Accessible via right click on heroes in the scoreboard.
