DistroWatch published two review on Ubuntu MATE 21.04 and Anbox.

Ubuntu MATE 21.04 and Anbox

he Ubuntu team published version 21.04, on schedule and without much in the way of surprises. Ubuntu and its many community editions, including Ubuntu MATE, appear to have spent the past six months polishing the desktop environments. There aren't many changes, no leaps forward in terms of the underlying technology like init software, filesystems, and packaging formats which sometimes shake up the Ubuntu community. This time around the big headline change for Ubuntu was adopting Wayland as the default display software for the GNOME desktop. Meanwhile the Ubuntu MATE team included some fixes, addressed some problems when switching between desktop layouts, and polished their themes.
