Aus heutigem Patchnote:

There are a couple of known issues that are serious and which make playing MP an exercise in frustration for the client right now. I'm having to juggle multiple things, so will hopefully have that resolved over the weekend or on Monday by the latest. Balancing that around the needs of the trailer work and related things is really tough.

Multiplayer is going to continue to see weekly updates, and continue to make rapid improvements (this past week or two has been a backslide in stability as I chased the ghosts problem), but it looks unlikely to be ready to call final on the 18th. We're going to stick with accurate names. Right now it's beta, and rapidly getting better. We'll call it done when it is.
