Looks like an open beta for Steam’s new library setup is arriving on September 17, according to a post on Steam Community.
Valve begins the post by explaining the ethos behind the Steam Library,
“The new Steam library was built with the belief that our libraries are valuable to us – for some customers, they contain more than fifteen years of games. From your absolute favorite AAA title that all your friends are playing, to that solo indie art project that only you seem to love, your Steam library represents your gaming history.
But, a good library shouldn't just be dusty shelves, it has to be a fun place to explore and find whatever it is that you're looking for. Whether you want to keep up to date about what's happening with your games, find a game to play with your friends, or explore what's happening in your game's community, your library should support you.
Today we want to introduce you to some of the biggest new library features and explain how they’re going help do just that.”
Along with a visual overhaul, the new design will make it easier to connect with your friends, and be kept up to date for the games you care about. Check out the full post here.
