In addition to Glenn's document below have a look at the supplemental agreement Glenn and I put together to transition NEC3 to NEC4. Not quite what you are after but it does pick up the most useful stuff (https://gmhplanning.co.uk/downloads/nec3-nec4-supplemental-agreement/).
Also have a look at the NEC4 supplement I wrote while at my previous firm which picks up the key issues, not as bullets but with some explanation (http://www.elexica.com/-/media/files/articles/2017/construction/4434577_1.pdf)
These are free also!
