Last month, Valve added all-new chat and friends features to Steam. Now, they're out of beta.
Everyone can now use the client's revamped messaging and social tools and, basically, they look a lot like Discord.
Crucially, the revamp works on both Steam's desktop application and its web-based version.
It looks pretty fancy, too, with dragging and dropping of friends seamlessly into groups, high quality audio chat, and lots of stuff you would now expect a modern chat client to have as standard - such as support for inline GIFs and YouTube videos and tweets.
Lots of tweaks were added over the course of the beta - such as the ability to hide offline friends, compact your friends list and collapse video embeds, for example.
Valve has a full patch list of changes, or you can just load up Steam now and see it all for yourself.
