The next major update for Ubuntu Linux is about to arrive, with the Beta of Ubuntu 23.04 'Lunar Lobster' now available. With the final release scheduled for April 20th, this will be one of the last times you can test for issues before the main release.
One of the major changes is their new installer, which is a Flutter snap, although the original installer is still around for people that have issues with the new one.
The majority of the user-facing changes are from their GNOME 44 upgrade though, so you should hopefully get a better performing desktop, along with the enhanced Quick Settings menu and lots more. My favourite feature there is that after years of waiting, there's finally thumbnails in the GNOME file picker (if the app is using GTK4). Hopefully more applications will upgrade to take advantage of the upgraded file picker.
Of course there's lots of other updated software included like Linux kernel 6.2, Firefox 111, LibreOffice 7.5.2, Thunderbird 102.9, BlueZ 5.66, NetworkManager 1.42, Pipewire 0.3.65, Poppler 22.12 and xdg-desktop-portal 1.16. They're also still testing their new Steam snap.
You can download the Beta below, depending on which you wish to test:
