I can’t speak for anything else, but I’ve read up to the Meta-ethics sequence without encountering any gaps. I can’t vouch for anything after that, but the pdf seems complete. Maybe someone else can shed a light on your question.
From posts like this one I got the impression that they were being edited and released together in a possibly new order. Maybe I am mistaken?
There was a plan to release two books. That was scrapped in favor of other uses of MIRI’s time/resources.
