2015 Engine differences

It looks that the FA20 engine was revised lately. I found the following differences in the 2015 model (manufacture year after July 2014):

valve-intake
valve-exhaust
camshaft sprocket
camshaft complete-intake (left, right)
camshaft complete-exhaust (left, right)
head and valve set-cylinder

Actually, they have different part numbers. Even the entire engine assembly has a different part number.

Any ideas why they made these changes? Any known issue?
