I just picked my new Freedom today from Port Rowan, so great timing on your post! I'm extremly impressed with the fit and finish and Mike was very accommodating in regards to customizing any feature you want, from lights, to blind, to paint scheme.
I can't really comment on any changes over the years as I have limited experience with the early model other than a tour of the prototype when it was first built, but I think the hull, blind and interior remain unchanged.
