oort, these are questions I cannot answer, so I transferred your question to DavidBluecame (here):
This was his answer:

About the visibility setting for Mesh Light and volumes, I would have to
check, but it's possible that it never actually worked.

Light portals are supposed to be just that, not objects casting shadows. As
far as I understand they just bring the background into the scene through
the surface of the portal object.
