This edition includes 833,596 type-I QSOs & AGN plus 654,560 radio/X-ray associated optical objects of 80%-100% likelihood of association, with a QSO-likelihood figure provided as well -- details are in the ReadMe. Gaia-DR2 astrometry is given for ~47% of the objects, i.e., as available.
Here is the ReadMe, and a quick browse of sample data (in flat text form) is here.

index to numerical citations in the file are here (from HMQ quasars) and also here (from MORX with galaxies & stars).
The paper for
Milliquas v7.2 is here
and also on arXiv
-- it details the inclusion of SDSS quasars up through DR-16Q.
An earlier paper for
Milliquas v6.4 is here
and on arXiv
. It gives some history and informal context.
