Update: It appears the widget for Google+ has disappeared in this update, and images now appear somewhat compressed and pixelated. It's unclear if this is intentional (It seems one of the app's developers has said the widget will return soon, over on Google+.)

The Google+ app team just dropped a surprisingly massive update onto the Market, and it brings changes galore. In fact, there's so many changes that they've called it a "completely new app." Take a look:

The UI has taken a turn towards the styling we've seen in Ice Cream Sandwich, and menus have been reworked to resemble the next version of Android as well. Here's the changelog from the Market:

    What's in this version:

    1. Completely new app and new visual design
    2. Battery life improvements
    3. Navigation and performance improvements
    4. Significant notifications improvements
    5. Brand new posting UI
    6. Several bug fixes
    7. Support for Google Apps users
    8. Ability to sign out
    9. Add people to a circle from circle profiles

"Significant notification improvements" seems to have entailed the end of the annoying pull-up notification bar, in favor of a counter at the top right of the app which more closely resembles the notification counter on desktop browsers. The settings menu now is organized in a more ICS-like fashion, with most of the options integrated into a single menu level. The posting UI has been totally overhauled, and the whole app generally just feels smoother.
