The Ubuntu Unity 22.10 has now been released; it is the first stable release of Ubuntu Unity as an official flavor. It introduces a new toggle from the panel to switch between the dark and light theme, and between accent colors. It also replaces all the libadwaita apps with MATE alternatives. The ISOs much smaller, at 2.8GB. The RAM usage has also gone down significantly (around 650MB when idle). You can now install Ubuntu Unity on an existing Ubuntu installation by removing gnome-shell and other GNOME apps, and then installing the ubuntu-unity-desktop package (all the Ubuntu Unity packages are now in universe in the official Ubuntu archive, and no longer in a PPA). We're actively working on adding new features to Unity7, such as support for different refresh rates in unity-settings-daemon, and even replacing such old components and apps and the indicators with the ayatana-* packages. We are working on adding extension support to the Unity shell.
