The Million Quasars (Milliquas) catalogue presents a new release,
v5.4 which includes all published quasars to 15 October 2018. The
long-term intent is to include SDSS-DR15 in July 2019 and probably
SDSS-DR16 in December 2020, but one step at a time.

The catalogue and ReadMe are available on
http://quasars.org/milliquas.htm
and on NASA HEASARC at
