Maybe stupid question, but I wonder. Version 8.5.2 was released 15 of June why does it say Built on Apr 29 on the startup screen? It says 8.5.2, so is everything fine?
Yes.
The build date will (should?) always be earlier than the release date for any software. They need some time after the final build to make sure everything works as expected before releasing it to the public.
Yeah, all versions of Cubase spend at least a month or two being tested before being released, same for Steinberg’s other products.
