All of them, as far as I can tell? I'll grab a screen shot of some of the space age content that it shows.
It seems to show less than it did before for some reason. I was seeing the new planets previously, but now I'm only seeing Nauvis / Space travel. But it still shows new buildings + the space platforms. I assumed these were also meant to be hidden? Maybe I changed a setting somewhere.
Sorry, but I don't see where to add attachments if I even can.
edit: I'm not sure how the simulations are selected, so maybe I need to wait a while to see a different planet
