A few days after I installed Debian 'Jessie' Release Candidate 3 on one of my laptops, the full release happened.
On 25th April 2015 Debian announced the release of Debian 8.0 'Jessie'.
Long-awaited by fans of Debian, like me.
This release gives the choice of several different desktops, not just Gnome.
These desktops probably have differing levels of accessibility, but as noted before, the Mate desktop seems to be very accessible and is a joy to use.
I will be posting a full installation guide in the next few days.
