Just as some were speculating that Google's invite-only signup system for their latest social networking venture would be its eventual downfall, the Google Mobile blog announced that Google+ is transitioning into beta, bringing open signups with it.
That isn't the only change Google has cooked up, though. Google+ has been updated with a host of new features in an effort by Google to show how fast they can implement users' "most requested features."
Perhaps the most exciting change to Google+ is the addition of Hangouts to the mobile app with the v1.07 update. This means you can execute group video chats from just about anywhere, using a clean, simple interface similar to the Google+ online interface.
