I’ve done a review of the early 2nd millennium BC. There isn’t a whole lot of evident progress: Mostly, I have been pushing interconnections of the nations and peoples already included. I have some slight broadening of the nations connected to particular institutions.   In the Individual centuries, I have been able to connect classical and medieval history far enough that I can do work connecting nations and peoples to it.  For peoples of the world, I can continue a program of adding cities, and for institutions, I am adding more nations.
