Debian 8 has finally been released by the Debian Project. You can grab the release and read about the latest changes here. In accordance with their “Toy Story” naming scheme, the “testing” branch has been renamed to “Stretch”. I don’t know when I’ll make the switch (to the new testing environment), but will probably do so when it becomes feasible.
So, go grab a blank DVD if you’ve got one, because (so far), Debian seems to be the best Linux distro I’ve used. Most of the articles I’ve written are with respect to users who are creating games within the GNU/Linux userspace.
