Ubuntu 21.10 brings GNOME 40 debut and a focus on devs

Ubuntu 21.10 comes out today, an interim release with nine months of support, and the first to use GNOME 40 for the desktop. The Ubuntu release cycle delivers a new LTS (Long Term Support) version every two years, the next one being 22.04 in April. This means that 21.10 is a handy preview of features that may not get production use until 22.04.
