See list for 2016 (they have a nice new map feature too):

And for 2020: https://www.wmf.org/2020watch

Some inspirational ones for a missing list (a Yezidi shrine near Mount Sinjar for example),

Plus a couple of WHS to add to the connection:
Kathmandu Valley
Paris, Banks of the Seine
Rapa Nui
Koutammakou
Bukhara

(still checking the Sacred Valley, may overlap with Qhapaq Nan somewhere)
(Canal Nacional seems likely for Mex City / Xochimilco, but I cannot find evidence that it is in the core zone (the 2 parts are separate))
