Lol, F40/G46 were released a full month ago 😳

So they changed (among with minor stuff)

Settings
- Reorganized tabs

File Manager
- Path editing and folder search (FINALLY they fixed UX on this one)
- Starred files (was it in v39?)
- Global search
- Better actions display (e.g. move/copy large files)

Notifications
- Actions in a drawer
- Reworked layout

General
- Calendar app redesign
- Redesign, I noticed only fixed headerbar in GTK and larger elements
- On-screen keyboard, touchpad, extensions improvements
