When I upgraded from Debian 12 to 13 on my personal laptop running KDE, I knew that the switch from X11 to Wayland would happen and was braced for all kinds of issues, like every other time I tried to switch to Wayland in previous years.

Instead, I could tell literally no difference. Multiple desktops works fine, scaling works fine, screen capture works fine, old apps work fine, literally everything works just fine.

Good job, KDE team.
