It's slow, and not great for desktop usage. Also, some apt packages have been transformed into snaps. If you do sudo apt install firefox it no longer installs the deb version, but the snap. I (and probably many other people) don't like this lack of transparency and choice. It just feels like getting snaps pushed down our throats.
That might mean it needs to be implemented at the distro level. Not the kernel. This means that any distro that won't comply will be illegal in California. I'm pretty confident this won't cause any issues for anyone outside the "Land of the Free".
That's because android doesn't let you do what you want. It treats the user like an idiot. Too many checks and "security" measures that boil down to "we don't trust you, and you shouldn't trust yourself, so we're making this harder.
Valve Steam Runtime 3.0 (I really don't know what this really improves, probably better game compatibility)
PS4 and Xbox360 emulator support (you can now have those console's roms neatly organized in lutris)
Gamecube emulator now runs using appimage (no more dependency issues, should work on every system)
Lutris now uses the more descriptive GPU info in vulkaninfo (Intel ARC GPU's no longer show up as 'intel graphics')
Lutris also changed its system information reporting. It now displays the Python version in its system information panel and reads the host os-release file when running inside Flatpak.(Basically, better for bug reporting and diagnostics)
User interface:
The sidebar can now collapse sections (can be used to make things look less cluttered, helps you see everything you're interested in without scrolling)
Uncategorized games can now be sorted
When a certain icon is unavailable, lutris now provides a fallback icon set.(Means that incomplete icon sets won't make Lutris impossible to use, you'll see mismatched icons, but it's far better than nothing)
A bug is fixed where categories would remain with their old names after being renamed.
Miscellaneous:
Proton versions are now grouped together with wine in the internal file structure, instead of being in separate folders.
A bug was fixed where wine would show a warning about running under Wayland to all users, even those on X11.
It's meant to look like Krita's mascot, Kiki.
Take notice of her ears and her eyes.
KDE's official site about Kiki, from where I sourced the image.
