Introducing new social features now available in the beta version of the Blizzard Battle.net® desktop app: the new Social tab, Blizzard Groups, profiles, avatars, and the ability to appear offline! To help get these into as many players’ hands as possible, starting today the beta version of the app is open to you and your friends—no invitation required.
To switch to the beta version of the Blizzard Battle.net app, simply open your app settings, click on the Beta tab, and then click Switch to Beta Version.
These features are designed to give Blizzard players even more ways to stay connected, and we’re looking forward to continuing to evolve the app and build even more ways for you to stay in touch and join forces for your next adventure.
