For those of us who can't seem to let a day pass without fragging someone in Valve Corporation's very excellent multiplayer FPS, Team Fortress 2 (PC, PS3, Xbox 360), here's a special news bulletin: the highly-anticipated Gold Rush update is now live and available for automatic download as soon as you restart your Steam client. This includes the Goldrush map, and the much-awaited Blutsauger, Kritzkrieg, and Ubersaw weaponry for the Medic. Wunderbar, we say!

Besides those key features, there's also a lot of changes made to the overall gameplay, such as the removal of a lot of exploits and glitches. So if you've ever noticed them before or even made them a part of your strategy, then you might want to look over the complete changelog so you'll know what sort of changes in your gameplan that you'll have to make.

In any case, here's the complete changelog:
