The newest Steam beta client update is all about that DLC

DLC is the way to be

Steam constantly improves itself, adding new features for us all the time. The latest beta client update includes DLC improvements, which adds in a “DLC view” to better see your add-on content. It not only shows your currently owned add-ons, but also what’s installed. It’s a neat feature since some DLC is bigger than base games these days.

There’s also a few minor fixes like push to talk improvements, and your “recent” list will include both purchases and played titles.
