First, everytime I want to pick 1.18/19/20 I need to scroll around.
Second, we support only N-2.
How about hiding them from the selection dialog up to N-3 versions? We can create one extra option named “Foreman Old Version” or something like that. Because I don’t believe it is very relevant if we get a fresh bug report on Foreman 1.11, I realize there is some information value for googlers however. Not sure if it is worth the effort tho.
