Is it confirmed the single hinge plate version made it to production? AFAIK this was only used for the box art. Would be interesting to find those instructions.
Here are a few sets with more significant changes:
6987 - redesign of the gate opening mechanism
6923 - Crane arm and rotor attachment redesigned
6851 - Chassis reinforced
6531 - Panels changed for 1x3 Slopes
Smaller changes would be something like this:
8880 - wheel attachment altered (including a new exclusive mold)
4563 - Train window replaced with newer more sturdy variant
6990 - later ones might have come with the more common thicker connector cable
