GPL-2.0-only
* Thu Sep 11 2025 Jan Engelhardt <jengelh@inai.de>
- Specifically request pkgconfig(cddgmp) now that it exists.
* Tue Sep 10 2024 Jan Engelhardt <jengelh@inai.de>
- Update to release 0.7
* Introduction of ``_tropicalprevariety`` which is much faster
than the old ``_tropicalintersection``.
- Add gfan-c++20.patch, gfan-gcd.patch, gfan-multiplicities.patch,
gfan-soplex.patch, gfan-warning.patch
- Delete gfan-warnings.diff & cddlib.patch
(replaced by gfan-warning.patch), delete gfan-odr.patch (obsolete)
* Tue Jul 13 2021 Alois Wohlschlager <alois1@gmx-topmail.de>
- Add gfan-odr.patch: A patch to fix ODR violations, which were
causing segfaults in the respective programs with LTO enabled.
* Sat Sep 19 2020 Jan Engelhardt <jengelh@inai.de>
- Add cddlib.patch
* Sat Aug 24 2019 Jan Engelhardt <jengelh@inai.de>
- Specfile modernization.
* Mon Dec 25 2017 jengelh@inai.de
- Update to new upstream release 0.6.2
* Improved mixed volume computation, improved Gröbner basis
implementation.
* New tropical starting cone algorithm, resultant fan
algorithms, tropical hypersurface reconstruction algorithm,
tropical basis detection (in _tropicalintersection -t was
replaced by --tropicalbasistest)
* Stable intersection of tropical cycles (_fancommonrefinement
- -stable)
* Better implementation of the field of rational functions).
- Delete gfan-format.diff, gfan-returns.diff,
gfan-remove-debug-code.diff (fixed upstream)
- Add gfan-warnings.diff
* Thu Jun 16 2016 jengelh@inai.de
- Add missing post and postun sections for ldconfig
- Build with std=gnu++98 because the code has not been written
with C++11's std::rank in mind.
* Sat Oct 11 2014 jengelh@inai.de
- Use source URLs
* Thu Sep 12 2013 werner@suse.de
- Make it build with latest TeXLive 2013
* Thu Dec 06 2012 jengelh@inai.de
- Add symlinks that are expected by other programs
