Locale file changes
C.UTF8 locale is now included in glibc:
Credits @diabonas for this change. Systemd wants us to include C.UTF8 by default and it seems the locale may be in included by glibc upstream in the future. To fix building and avoid nasty fixing in devtools, we include the locale in the package. See systemd/systemd#23252 (comment) FS#74864 : [systemd] >= 251 breaks devtools' locale
There is a pacsave for /etc/locale.conf as it has been removed from the filesystem package. /etc/locale.conf will automatically be restored if it did not already exist.
There is a pacnew for /etc/locale.gen. Please review it and regenerate your locale if necessary.

Chromium / Google Chrome cannot save files to most folders (GNOME and Xfce)
This is an upstream bug with the package xdg-desktop-portal-gnome
In the meantime, you can try to remove the package xdg-desktop-portal-gnome (if feasible, without any dependency issues or conflicts), or wait for the bug to be fixed upstream.
Without any xdg-desktop-portal-* packages, Chromium and Google Chrome should correctly detect the environment and present either KDialog (KDE) or GTK file picker (GNOME, Xfce) upon saving and downloading files.
An alternative workaround, for now, is to intentionally click on the filename field, and then press Enter to save / download the file.

KeePassXC auto-type does not work
Upgrading KeePassXC from version 2.6.6 to 2.7.0 partially breaks the “auto-type” function. This is fixed upstream in version 2.7.1.
In in the meantime, to have it behave (and work) as it did with version 2.6.6, change the following option:
Tools → Settings → General → Auto-Type → uncheck “Always ask before performing Auto-Type”
Version 2.7.1, which did not make it into this batch of Stable Updates, works correctly, even with the above option enabled.
Desktop Icons (DING) Gnome extention and File Previews stop working due to a crash in sushi.
