diff_versions

Compare two consecutive versions of a served dataset row by row on its key fields, to see what a publisher changed between releases. from and to must be adjacent dates in the version history from get_dataset, older first. Any other pair returns a 404 error, so step through a longer span one pair at a time. A dataset with no key, which list_fields shows as an empty key, gets row counts only, and a dataset with one version has nothing to compare. One answer holds the counts of rows added, removed, changed and unchanged, the keys of the rows added, removed and changed, and up to ten changed rows with their old and new values. The call costs nothing against the rate limit.
