2. Hangouts on your phone :
In life we must have been connected with others in all sorts of places, at all different times. And the connections you make unexpectedly are often the ones you remember the most. But Google+ thinks Hangouts should keep pace with how you socialize in the real-world, so today they have launched it on the one device that's always by your side: your mobile phone. To get started, simply find an active hangout in the Stream, and tap “Join”:

But for now Hangouts are currently supports Android 2.3+ devices with front-facing cameras (and iOS support is coming soon). The new mobile app is rolling out to Android Market today, so you can start hanging out at any time, from just about anywhere.
3. Hangouts On Air
Google+ users already use Hangouts to create intimate onscreen experiences—with family members, prayer groups, even people with certain medical conditions. But sometimes you want to speak to a large audience, or alternatively, view as a spectator. In these cases a public broadcast is what’s needed, so they have introduced Hangouts On Air.

The setup is simple enough: just start a normal hangout, and you’ll have the option to broadcast and record your session. Once you’re “On Air,” up to nine others can join your hangout (as usual), and anyone can watch your live broadcast:

7. Named Hangouts:
It is useful when you want to join or create a public hangout about a certain topic (like fashion or music or sports...)

The extras are still under construction, but as Google +wanted to preview these features and get your feedback sooner versus later. So they recommend to start a hangout, click “Try Hangouts with extras” in the green room.
8. Hangouts APIs
If field trial has taught Google+ anything about Hangouts, it’s that the community is overflowing with creative individuals. So in the wake of last week’s Google+ API launch, they are also releasing a basic set of Hangouts APIs. If you're a developer who wants to build new kinds of apps and games (and who-knows-what-else), then you can find more details on the Google+ platform blog.

9. Search in Google+
We people were asking for it, and theywere busy building it, so today Google+ is bringing Google’s search expertise to Google+. Just type what you’re looking for into the Google+ search box, and they will return relevant people and posts, as well as popular content from around the web.
If you’re into photography, for example, then you’ll see other enthusiasts and lots of great pictures. If you care more about cooking, then you’ll see other chefs and food from around the globe. In all cases, Google+ search results include items that only you can see, so family updates are just as easy to find as international news.

For the past 12 weeks were into the field trial, and during that time Google+ just listened and learned a great deal.Google+ is nowhere near done, but with the improvements they have made so far n they are ready to move from field trial to beta, and introduce their 100th feature: open signups. This way anyone can visit google.com/+, join the project and connect with the people they care about.
