The newest version of the Google+ app is the latest in a string of updates for the service that has kept up since Google+ launched at the end of June. These constant updates have perhaps helped Google+'s growth--the service is barely a month old, and it already has over 25 million users.
In addition to iPad support and a few bug fixes, the new version of the app also has a few updates for iOS users in general. Notably, the update brings new features to "huddles"--the service's free mobile chat feature. In the updated version of the app, users can hide huddles, set permissions for who can and cannot start a huddle with you, and launch new huddles from within a profile page.
Though Google has been constantly updating its new social network, the service still lacks some features. For example, the new iOS app doesn't support Google+'s hangouts video-chat feature, and Google+ still hasn't added business accounts. Google+'s growth so far has been impressive, but it still has a long way to go to catch up with Facebook's 750 million users.
