rebase to new upstream version 1.7
- dropped all patches (almost all issues are fixed in new upstream version, sometimes in different way) - only patch gzip-1.3.12-openbsd-owl-tmp.patch is untested - code is changed significantly and patch is undocumented from archaic time, so I drop it too Resolves: #1321560

* Tue Apr 05 2016 Petr Stodulka <pstodulk@redhat.com> - 1.7-1
|
||||
- rebase to new upstream version 1.7
|
||||
- dropped all patches (almost all issues are fixed in new upstream version,
|
||||
sometimes in different way)
|
||||
- only patch gzip-1.3.12-openbsd-owl-tmp.patch is untested - code is changed
|
||||
significantly and patch is undocumented from archaic time, so I drop it too
|
||||
Resolves: #1321560
|
||||
|
||||
* Wed Feb 03 2016 Fedora Release Engineering <releng@fedoraproject.org> - 1.6-10
|
||||
- Rebuilt for https://fedoraproject.org/wiki/Fedora_24_Mass_Rebuild
