The Git history is not useful. It has no details of why.

Two distributions have already transitioned from ImageMagick 6 to ImageMagick 7 by default: PLD (December 2016) and openSUSE (March 2017). As a result of that, a number of packages have already been made compatible with IM7 over the past five years. Incidentally, this means ImageMagick 7 is part of SUSE Linux Enterprise 15. When I went through and rebuilt things, most things *just worked*. I had to do a very simple tweak to the ImageMagick package to make it easier to make stuff that's compatible with both find the IM7 headers, and all but 5 packages built. Only two packages needed patches to introduce IM6/IM7 compatibility, and one of those isn't dead upstream. I'll send the patch upstream for that package. There are actually other packages I could fix in Fedora with patches from openSUSE or PLD, but they need more work to not break compatibility with building with GraphicsMagick (which these packages in question support), so using IM6 there for now is fine while that gets worked out. I only said we should do it because I know it works. Not doing it propagates this problem of continuing to default to the legacy version. As an aside: I don't appreciate the "high horse" comment, considering during most of this discussion, I was doing the work and evaluating things. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
