Almost after two and half months Google+ is now over from its testing phase and open publicly for anyone who  wish to join the service. According to Google’s senior vice president Vic Gundotra, "We think there’s lots of room for innovation".

The most liked and demanding feature over three-month old social network Google+ is the ability where user can interact with multi-person live video call named as ‘Hangout’, this multi video conferencing feature is found on popular calling software Skype, but now the features resides comfortably with Google+.

The previous day Google has announced some four latest features upgrades with Hangouts, have a brief over below to the features:

Hangout Broadcasting

Before the upgrade Hangout’s were limited to small group of about 10 users, ‘Hangout On Air’ now allows to start a normal hangout where you can invite 10 participants and broadcast your voice for everyone to see. The features is useful for official meetings, a small seminars or study discussion among your friends.

Hangout Collaboration

Do not restrict yourself with just video calls or live conference calling, check out Hangouts latest feature called ‘Hangouts with Extras’ which supports screensharing like in Teamviewer, shared sketchpad, even you can work on Google Docs in a conference.

Mobile Hangouts

Previous Google+ app didn’t support Hangouts, if you are Android 2.3 users then you can take the advantage of Google+ as front facing camera supported phones can now join Google+ Hangouts on their phone. You need to upgrade your previous Google+ app with available one from Android Market Today. Sorry to iOS users (including me) the functionality will soon be available.

APIs

Google have just released the very first API for Google+ a few days back, and today a developer preview for basic Hangout APIs has been released. Richard Dunn, Technical lead from Google+ Hangout platform describes the actual model and the process when/how your app goes live.

"The integration model is simple — you build a web app, register it with us, and specify who on your team can load it into their Hangout. Your app behaves like a normal web app, plus it can take part in the real-time conversation with new APIs like synchronization. Now you can create a “shared state” among all instances of your app so that all of your users can be instantly notified of changes made by anyone else. (This is how the YouTube player keeps videos in sync.) And we’ve added our first few multimedia APIs so you can, for example, mute the audio and video feeds of Hangout participants"
