Unreal Development Kit Updated With Steamworks

Epic notes that "Steam now handles friends, matchmaking and server browsing in the UDK," the same systems that are used in Valve's Team Fortress 2 and Left 4 Dead.

Other new features include support for Scaleform's Flash-based user interfaces, attractive new light shafts and fog, performance improvements, tweaks and fixes. The full changelog for the May 2010 Unreal Development Kit beta follows below.
