Please apply the following patch to fix a dependency issue with libzstd-dev and
a set of backported patches from the upcoming (yet unreleased) 4.15.0 release to
make rpm compatible with newer DNF versions (required for my other work).
These patches merely introduce support for new three new tags and should be very
safe to apply.
When applying the debdiff, please remove the NMU entry, which is only there to
make lintian (more or less) happy!
