I wondered about the same thing, and did some digging myself
yesterday.  The commit seems to have been merged to their 'master'
branch with the commit 0418c172 (Merge branch 'master' of
../docbook-fixed, 2015-09-20), which is after a curious 5 year gap.

... even if the fixed release was done in 2016, I would say that it
shouldn't be too recent, especially for documentation where we still
give preformatted ones (which I think about dropping once every few
years).
