My guess is Debian -- the pacemaker package stagnated in Debian for a
long time, so the stock Debian packages were at 1.1.7 as late as wheezy
(initially released in 2013, but it's LTS until 2018). Then, pacemaker
was dropped entirely from jessie.

Recent versions are once again actively maintained in Debian
backports/unstable, so the situation should improve from here on out,
but I bet a lot of Debian boxes still run wheezy or earlier.
