Comparison between the 2014 and 2016 version. (2014 version is on the left).
With the 2016 version the heatsink is about 18mm shorter. Use the slider to see the difference between the two. (The photographs come from different cameras/lenses/focal lengths so offer slightly different views of the two circuit boards but you should get the idea).
