Overpass: Find all tracks with specific change of tracktype

Hello everyone,

i am looking for a way to find all highway=track whose tracktype was changed from grade2/3/4/5 to grade1 with the last change.

On this page there are two examples to output all versions of an object (search for "timeline"):
https://wiki.openstreetmap.org/wiki/Ove … by_Example
In a similar way, is it perhaps possible to compare the most recent and the previous version and output tracks where such a change is detected?

There is also the keyword "diff", but here I am not quite sure how to use it either. Also, an exact date is expected here.

I know that I could just download all versions and filter the data in some other way, but I'd like to be able to display it directly on Overpass Turbo.

Thanks a lot
