Steam Winter Update Released - Garry's Mod and DEFCON Update

As I reported a couple of days ago, the promised "Winter" update to Steam has been released. Included in this release are "Guest Passes" and a "new" GUI for the Valve application. Guest passes, well they are exactly what they sound like - guest passes for games. The first game to offer guest passes is Day of Defeat: Source. A "new" GUI has also been released, and by new they mean just a redone original skin, with new color offerings. Needless to say it is a fairly substantial update to Steam. All you need do is restart the Steam client and you will automagically get the update. Here is the changelog for the update for those of you who missed it the other day:

Added Guest Passes functionality - allows owners of certain Steam games to let their friends play games for free, for a limited time trial
Changed Steam client auto-update mechanism to first acquire updates in the background and then ask user whether to restart & apply
Added Favorites area and collapsable status categories to 'My Games' list
Added 5 new colored skins (Default, Ice, Sand, Obsidian, and Grey), selectable in "Settings"
Added 'next' button to Steam news window, allowing multiple messages to be viewed in a single session
Fixed client attempting to update some games which user does not own; was occuring when user had played game during a Free Weekend
Fixed games purchased via PayPal not working in offline mode

An update to Garry's Mod (version 10) and Introversion's Nuclear War RTS game DEFCON were also released at pretty much the same time. Just like with the Steam update itself, you need just log into the client and both Garry's Mod and DEFCON will both update. Please be advised, if you download the patch from the Introversion site for DEFCON, it is not compatible with the Steam version of the game. Check out the extended news area for the changelog for both updates. Enjoy everyone.
