I don't understand this sentence of yours.
The debian revision in a version doesn't convey any particular meaning
about the "dimension" of the changes.  In fact going from 2.8.7-1 to
2.8.7-2 could techinically ship a completely different upstream tarball
with completely different code in it, still you would call that a "minor
upload"?

So everything could have happened in between.

Please also read the rest of my email, that's what I deduced and
recomended as well (apart from suggesting a particular name for the
binary).

Also, before doing that somebody should check all the other binaries,
and verify they didn't change their ABI either.


BTW, it bothers me quite a lot that such a big change as moving from
VTK6 to VTK7 has not been mentioned in the changelog at all.
