We'll keep building for Lucid, Precise and Wheezy as long as we're
supporting LinuxCNC 2.7:

http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MinimumSoftwareVersions

Building for old distros doesn't cost us much, since the infrastructure
is already in place and pretty much just keeps running without much
effort on our part.

Per that wiki page above, we're supporting LinuxCNC 2.7 on Ubuntu Lucid
and Precise, and Debian Wheezy, Jessie, and Stretch.

We're not currently promoting Ubuntu-based installs because of changes
in (or maybe clarifications in our understanding of) Canonical's
attitude towards derived products.

We strive to make it easy for non-Linux-gurus to install LinuxCNC, by
providing installer ISOs based on upstream (Debian or Ubuntu)
installers.  Canonical recently made it legally onerous to produce
derivative installers.  This was one of the major factors prompting us
to switch our focus to Debian during the Wheezy time frame.

Adding support for newer distros and producing installers ISOs with
realtime kernels for those distros is a significant effort.  Jeff has
done a fantastic job making sure we run well on RT-Preempt, and
producing installer ISOs based on Stretch and RT-Preempt.  These are not
officially released and not widely publicized yet, but I believe they're
ready for wider distribution.
