I am not fully sure what they are doing. They do increment values sometimes, sometimes they keep them. I mostly just followed along. We also for a time tried to accomodate lagging Debian packages. I do not think that that winnable strategy long term. I could add a versioned breaks for libmath-gsl-perl.
