In 4.4.5 the methods were included. In 4.5.X there are no payment methods included that are non-compliant. I believe that is why the version incremented into the 4.5 branch, it was a significant change.

So it works in the older version, because the methods are there, new version they are missing. Sure you can always install an older version and run that, question is, do you really want to? Security concerns and improvements aside, you don't want to make a decision to get "stuck" in an old branch.
