says the following:

Users might ask why we are not running Windows 10 x64 RS4, the latest major update – this is due to some new features which are giving uneven results. Rather than spend a few weeks learning to disable them, we’re going ahead with RS3 which has been widely used.

What are these new "features" the author is talking about?

(Also, isn't the latest major update RS5? Aka v1809.)
