Yes they have changed. Along with doing oil changes at 24,000km just like the manufacturer recommends! Modern technology eh!

They do say 24,000km or 1year on the oil right in the owners manual sooooooooooooo
I only put on about 5K/year so do them yearly as prescribed, in the spring just before towing season.
Project Farm did an episode on his 2nd gen(?) and a tractor that debunked the need based on oil analysis and while I value his reviews, I'm sticking to the OEM recommendation.

Can the 2021 6.7 use API-FA4?
Took this from the shell site
"Shell ROTELLA® T5 Ultra 10W-30 is suitable for use in 2017 as well as some late model engines allowing an API FA-4 diesel oil in this viscosity. Some engine manufacturers do not yet approve the use of API FA-4 engine oils, while some allow limited backwards compatibility to earlier model year engines. Check with your original equipment manufacturer regarding the use of API FA-4 diesel oil."

The NON-Ultra seems like the right choice.

AFAIK, Cummins has not approved the use of FA-4 oils in any B series engines.
