  • Updated libpng10 to 1.0.49 and then 1.0.50; the 1.0.49 release had some unfinished editing cruft left in it (much like the 1.0.45 release had), resulting in this patch being needed for compilation to work:

  • I notified the upstream author and 1.0.50 was promptly released to fix the issue

  • Updated libxml2 to 2.7.4 (security patches upstreamed and lots of other bugfixes)

  • Updated perl-HTTP-Size to 1.13_01 and patched some of the test URLs to point to places that still exist

  • Updated perl-IO-Tty to use %{?perl_default_filter}

Fedora Project

  • Updated libpng10 in Rawhide to 1.0.50 as per local package
