Found this on FB regarding hangouts on air. Couldn't find it here, but oh well. Here it is.
Hangouts On Air is moving to YouTube Live on September 12th
Hey there Create! We wanted to let you know that we’ll be consolidating our live streaming efforts by moving Hangouts on Air to YouTube Live on September 12th. After that date, as Google+ continues to grow into being the best place to find incredible content through Collections and Communities, you will no longer be able to start Hangouts on Air from Google+. You will, however, continue to be able to start Hangouts on Air on YouTube Live and share them on Google+. Hangouts on Air has been available on YouTube Live since its launch and we feel that YouTube Live is the natural new home for this service.
When Google+ was redesigned in November 2015, we pivoted away from being the social fabric between all of Google’s services to a more concise, targeted vision. That vision, as you all know, is to help people connect through their interests - specifically through a commitment to Collections and Communities. The decision to move Hangouts on Air to YouTube live is consistent both with the plan we announced a year ago to separate Hangouts from Google+ and with where we want to take Google+ in the future. By moving Hangouts on Air to YouTube Live, Google+ becomes a simpler, more user friendly destination where people can immediately discover incredible content and connect to the people behind it.
I’m sure there will be some questions about this transition, so without further ado…
Is Hangouts on Air going away for good? No. You can start Hangouts on Air through YouTube Live.
Will all of Hangouts on Air’s features be available on YouTube Live? Most! As part of this transition, users will lose some functionality, including the apps Showcase, Applause and Q&A along with Google+ calendar integration for HoA event invitations.
So, are there any alternatives to those apps in YouTube Live?
- Q&A: Live Streaming Events in YouTube Live have a feature called “Live Chat” which can be enabled in the “Advanced settings” tab. Moderators can be assigned to help moderate the questions that are asked through live chat. We also suggest using social media apps to gather and respond to questions.
- Showcase app: Links can be added to the Event’s description. When you go to create the event, there's a description field.
- Applause app: There is currently no alternative for this feature at this time.
What do I do about Hangouts on Air that I have scheduled? If you have a Hangout on Air scheduled on or before September 12, you’ll be able to host it with no changes. Beginning on September 13, you’ll need to schedule Hangouts on Air from YouTube Live.
Will I still be able to find my past Hangout on Air’s? Yes, absolutely! Past Google+ HOA events will continue to be available on Google+ in a read-only state. The recording of the event itself will be on YouTube as it is today. We are also actively working on a Google Takeout service in order to be able to download Q&A data from previous Google+ HOA events and the Help Center article will be updated with more information soon.

Phew! I know that’s a lot of information to digest, but I hope that it’s comprehensive enough to get the biggest, most obvious questions out of the way. If you have any other questions, please don’t hesitate to let us know below.
