Genealogy.com bought the program UFT from Palladium. Genealogy.com never created or worked on a new version of UFT. Family Tree Maker was already in existance and the two programs are and have always been separate. Even now Genealogy.com owns Generations (previously of Sierra) and it's files will not and never will work with Family Tree Maker.
UFTREE.com was part of Genealogy.com and was taken down after MyFamily.com purchases Genealogy.com. Since MyFamily.com still owns the domain UFTREE.com, it has naturally decided to promote and advertise it's current program Family Tree Maker. However, Family Tree Maker is not advertised, designed, or promoted as an UPGRADE from UFT.
