The latest version of Valve's non-beta Steam client has been released and has added quite a few changes, including non-Beta availability for Steam Broadcasting and an FPS counter in the Steam overlay, as well as plenty of bug fixes.
In addition to the new features, which include Steam Broadcasting, which is now no longer available for those that picked to get Beta features, as well as the new FPS counter, which has been added to Steam overlay, the new Steam client version also has fixed the previously reported
data loss bug on Linux, as well as a bunch of bug fixes for Steam Big Picture mode, In-Home Streaming feature, general usage and
quite a few other bug fixes.
The biggest feature is the Valve's response to Twitch.tv game streaming as now users can stream their gaming sessions via Steam client as well.
