Google's pushing out a new update to the official Google+ app. The red's a little redder, the floating action button's gone red with a redesigned white pencil, instead of white with a red pencil, and the shadow gone.
Update: Ah, and the Photos end of things has gotten a pretty good redesign. So it's still duplicative, but it also looks much better now.
See any other changes? Shout out in the comments.
