I am currently working on the tool that is able to compare two versions of fhir and show the differences in structure definitions/search params, etc. I ve encountered the following problem: in general there is no way to determine renaming of elements. Now I just compare names and if one is the substring of the other elements are labelled the same. So I wonder if fhir community can provide (preferrably machine readable) changelog from which I can easily identify that type of change. Or maybe there is the other solution which I do not see?
