The Google+ app for iOS has been updated to bring some features that had hit Android a while ago including resharing posts, setting your user profile picture, and creating new Circles. Unfortunately for those of you who are annoyed by it, the app is still essentially an HTML5 wrapper rather than a proper native app.
The update brings a few bug fixes including improving autocomplete in Huddles, properly refreshing notifications when returning to the app, and fixing issues when using Google's new 2-step verification on your account. The bigger changes to the app are the features of course. As mentioned, you will now be able to set your own profile picture directly from the app, and create new Circles for easier organization of people you're following. But, the number one change is the addition of resharing posts. This was a feature that was also absent in the original G+ app for Android, and is a key feature to have.
