You can see in a few pics that I snagged from them the differences right away. The screen shots on the left are the old Google+ and the ones on the right are the new Google+. Google moved the notification box from a lower level banner to a small counter at the top right. It really makes the opening page look a lot better. They also added a counter to the ‘Chord’ section as well, I don’t use the app much so that might have been old. In the image below you can see the new viewing style. Keeping true to a lot of the new swiping navigation and the ICS blues.
Enough rambling about the changes. I know you guys are only here for the download. Before I offer up that link, be sure to check out the full review and all the differences as posted at AndroidPolice. Great work guys.
[Update] Apparently many of you have had issues installing this app. You have to uninstall the current version of Google Plus before you can install this one. It is just like installing a modded version. Same goes for the Google music app.
