Updates for Groove Agent release notes?

Saw these updates pop up in the SDA today and wonder what they are. Anyone know if there are release notes?

I don’t think I’ve ever seen release notes on content (as opposed to applications).
In my case, I only see the GA Factory Content update, and it’s only 1.24GB, so I guess it depends on what you’ve installed previously.

It might be to address the present errors in earlier versions of Cubase.
