Yes. Many of the core areas of the software were adjusted which requires replacing those cores. I'm not a programmer, but as a beta tester it seems like working on software as complex as Carrara is a bit like squeezing a balloon full of water in your hands that keeps having water added to it. The goal is to not have any part of the software pop out between your fingers. But when you push in one place, it pops out in another. The computer code is connected together in ways that I don't even want to try and figure out!
