It seems like Google Analytics is now showing some of Google Discover traffic, likely from the Google News Showcase. If you check your acquisition, source and medium traffic, you may see [newsshowcase / discover] in the list.
Vishal Marathe was the first to spot this and post about it on Twitter, from what I can tell:
@VorticonCmdr @glenngabe Coming across this source/medium traffic from last few days for a publisher site. Have you seen this before? pic.twitter.com/oaUQhm3C0m

Valentin Pletzer and Glenn Gabe dug in and discovered this was likely coming from the Google News Showcase product. Valentin wrote "Looks like Google News showcase does attach utm-parameters to the URLs." Glenn Gabe added "Yep, I'm seeing that too starting on Thursday 7/29. And when you dimension by country, it's from countries running Google News Showcase."
Great catch Vishal. Yep, I'm seeing that too starting on Thursday 7/29. And when you dimension by country, it's from countries running Google News Showcase. pic.twitter.com/hluBNmUT7q

It also can show up in your real time view in GA:
Hello @rustybrick @glenngabe @lilyraynyc , In GA real-time I'm noticing a new source 'Discover' starting from today. And it going under the traffic source 'Other'. Is this a new one. Is Google splitting up the Discover traffic from the Organic. pic.twitter.com/iHSUnNrfLp

This is a nice addition but it does not yet show all Google Discover traffic yet, I don't think.
But maybe?
a colleague of mine just made me aware that even non-showcase cards get tagged with ?utm_source=newsshowcase&utm_medium=discover&utm_campaign&utm_content cc @rustybrick

Forum discussion at Twitter.
Update: This might be a bug or not working as expected - but it seems the GA team is working on bringing us this Discover and/or News Showcase data:
I don't have the full insight into this change, but I think the idea at the moment is to pull this back and make sure it's less confusing first. Overall I think you'll like it, but let's give the team some time to figure out the details & plans :).

We've been looking into it but don't have any details just yet.
