Google + upgrade to v5.0 – minor color and settings UI changes
The settings UI has been changed in the sense that the light blue accent color is now dark blue, the spacing is a little bit different and each item in the accounts settings is separated from the rest. The background color changed from gray to white. If you want to update your G+ manually you can go to the link below, or you can wait for the automatic update to pop up on your screen soon.
