This release brings a grid view in the file chooser, improved settings panels for
Device Security, Accessibility, etc, and refined quick settings in the shell. The Software
and Files apps have seen improvements, and a whole slew of new apps has joined
the GNOME Circle.
The release notes have all the details. The grid view in the file chooser alone would be worth a major version bump, considering how long it took them to implement it.
I did not think gtk would survive, my prediction was wrong. Here we are with an even worse linux desktop than ever before.
