Steam’s redesigned library

Valve launched a beta for a redesigned Steam library, and today that redesign is available for everyone. The new library has a refreshed visual look, intended to make it easier to find your games, see what your friends are playing, and follow news and updates from the games in your library.
Developers can also post updates to this What’s New section, as well as to a game’s community hub and store page, using a new tool that Valve is calling “Events"
