We got new app icons almost immediately after Google announced a new logo last week, but not Google+. It's been languishing with that old icon. Well, it steps into the future today, like it or not. Google+ v6.3 has the new round icon from the web. That's it right above.
So is there anything else going on in the new Google+ app? Maybe. We're still looking, but there's nothing really sticking out for us yet. It's possible the new icon is the only user-facing change.
You can grab the APK from APK Mirror if you don't want to wait for the update to hit the Play Store. And really, who can resist a new icon?
