Just logged into the CS and saw this-New YouTube Update

[Boris Qs]

As of September 18, 2017, we’ve added additional subscription sources to make it easier for you to analyze patterns and fluctuations in subscriber data.

You can now see more granular data in the sources report. For example, you can see all subscribes from interactive features, such as end screens.

Here are the source categories that you can see in the report:

YouTube watch page:
Your YouTube channel:
Interactive features:
External:
YouTube home:
Other YouTube channel:
Subscriptions feed:
Subscriptions channel list:
YouTube search:
Closed accounts:
Other: Subscriptions from unspecified sources.

I just saw a notification at the top of my analytics page and I'm SO PUMPED for this
I'm so happy they included something like this, knowing lots about my analytics and how/where/when my channel grows or shrinks, where my traffic is coming from and which videos get the best 'minuets watched' all help me improve, and this is another step forward!
Very happy with this addition, to say the least
