It looks like Google isn't abandoning Google+ after all. The social network (and photo sharing) app just received a huge interface makeover, laying credence to the idea that despite Vic Gundotra's departure, Google won't leave Google+ on the back burner.
The update trades in the static gray bars for vibrant red ones, and rather than utilize a "hamburger" pull out navigational menu, now there's quick access at the top of page. From here, you can access everything: your circles, your community, as well as Locations, Events, and Photos, including the new Stories feature.
Large photo libraries are also now supported on the Android app. It's interesting to note, however, that Google+ and the Photos app are now treated as two separate apps rather than one linked entity. Photos still has the pull-out menu interface of the days of yore, while both the Locations and Events page stay contained inside the Google+ app.
