I’ve searched in these pages:
but I could find only a link to the Silverblue issue tracker.
I was curious to find out how the image is built.
And I was also wondering when I could expect some GNOME packages in the image to be upgraded from 40.alpha to 40.beta (e.g. gnome-shell 40.beta released two days ago). I’m using Fedora 34 Prerelease (Silverblue).
