Sat Jul 2 13:32:33 UTC 2016 - zaitor@opensuse.org
- Update to version to version 0.2.8:
+ Fixed the document rotation with newer versions of Ghostscript
(fdo#76450).
+ Build was also broken with Ghostscript >= 9.18 and has been
fixed.
+ Fixed a compile warning due to a comparison of integers of
different signs when building on OS X (fdo#56476).
+ Makefiles were updated to properly use CPPFLAGS instead of
CFLAGS (fdo#56481).
- Drop libspectre-gs-9.18.patch and
libspectre-rotate-documents-correctly.patch: Fixed upstream.
- Drop zypper BuildRequires: It was only needed for above patches.
