Ive never heard of RE changing the oil filter and I can't think of one good reason they would do it.
They might have changed the kit number because originally, the filter kit included some extra O-rings to rebuild the spring loaded thing that pushes on the filter body but they changed that to something that doesn't need to be taken apart and it doesn't need to have anything replaced in it.
The basic filter is the same as it always was.
I might add, the O-rings don't need to be replace 99 percent of the time. If they don't have any rips or tares in them go ahead and reuse the existing rings.
