Enhancements to Panzer III/StuG III kits over the years

[LesBernell]

I have seen enhancements to newer releases of kits.
I was wondering what enhancements, that were integrated into newer kits, should be integrated into older kit builds.

What I have seen so far:

A 2.5x16 pin was added to the suspension arm (CL0204) for the 2018 Panzer III kit (my 2018 Panzer III kit had this enhancement).
A M4x22 PIN was added between the Road Wheel (CL0201) halves to hold them together for the 2020 StuG III kit (I'm adding this to my 2018 Panzer III build).

Does anyone have any other enhancements that I or other builders of earlier Panzer III/StuG III kits should implement?
