That's correct. There is no change to Docker CE or Docker EE. We are adding a 3d thing, upstream from both of them: Moby. We use Moby to assemble all the pieces of Docker. You can also use it to assemble all the pieces of other things like Docker, and maybe in the process collaborate with Docker on the common parts.
