It's in development.
It's usually a pretty good development period. Then it's beta tested by a private beta group.
Then when that's settled, it gets put the the members area as a "beta". Then when it's tidy enough, it comes out as a public release.
I don't know the timetable.... but I think it'll be a while.
But while it's in development, with each new feature/change, Rick will update that changelog.
