http://store.steampowered.com/uiupdate/ "As of today, a new version of Steam is available through a public opt-in beta, open to all Steam users. This Steam update provides several major upgrades to the platform's core functionality. We've overhauled the Steam user interface to enhance the way you already buy and play games, adding more info about the things that matter — getting games, playing them with friends, and staying current in the gaming world. If you already have Steam installed on your computer, you can take part in the beta by clicking this link and then selecting "2010 UI Update" under Beta Participation. If you don't have Steam installed, download it today. Following is a preview of the beta — read on to see what's new. When you're done reading, try out the beta, then head on over to the forums to let us know what you think."
