Previously only offering support for iPhone, the new app will allow users to do Google+ Hangouts from their iPad as well. It also supports Google+ Events -- a potentially useful feature where users can pool and display event photos.
Google notes that it designed the new app with the iPad in mind. In its blog post, the company pointed out some new, interactive features:
Pinch and expand posts right in your stream to add your comments
Use two fingers to drag a post from your stream to easily re-share it
Start a Hangout from your iPad and stream it to your TV using AirPlay
Google announced at its developer conference last month, Google I/O, that an iPad-friendly version of the app would be coming soon. It's now available in the app store.
The first version of Google+ for iPhone was launched about one year ago, and was last updated in May.
