There's already a ton of DB changes for B6 to B7, so and upgrade from B6 to B7 doesn't seem viable. Since Boonex has not been accepting any tickets that involve adding features (unless critical), maybe the DB changes will slow down and B7 bugs will be fewer.

I really think Boonex wants to release a product as much as anyone here. I'm not sure B7 will be the last beta, but I dont' see it going past B8.
