It seems that Jolicloud has made their "Final" release available, although selectively. According to The Jolicloud Blog, they started making the final release available last week, by invitation only, to existing Jolicloud user/members.
A good friend sent me such an invitation (thanks for that, and thanks for thinking of me!), but when I try to follow the link, I get a "page not found" error. In any event, I expect that the final release will be generally available before too long, and when that happens I will try it on a few of my computers. If anyone else has installed the final release already, it would be very interesting to hear about it.
