having L4 scholar's package together with some foreign language bibles and certain other individual books in my library, I do not want to necessarily want to extend my library at this time.
Considering updating "the engine" to L5, should I purchase just a L5 "Starter" package in order use my books with the new "engine features" or will a "free crossgrade" (is this even available yet?) do?
Also, will my existing library be automatically updated to L5 format when I update the "free engine" to L5? or will I need to purchase a different L5 "package" in order to use the new engine features with original language bibles, etc?
