* Tue Jul 28 2015 Ting-Wei Lan <lantw44@gmail.com> - 5.2.0-2
- Rebuilt for Fedora 23 and 24

* Fri Jul 17 2015 Ting-Wei Lan <lantw44@gmail.com> - 5.2.0-1

* Wed Apr 22 2015 Ting-Wei Lan <lantw44@gmail.com> - 5.1.0-1
- Update to new stable release 5.1.0
- Drop untested and possibly non-working Java support.
- Drop bundled CLooG because it is no longer required in GCC 5.
- Drop bundled ISL because it is now available in Fedora repository.
- Remove libcc1.so to prevent conflict with gcc-gdb-plugin.

* Fri Mar 20 2015 Ting-Wei Lan <lantw44@gmail.com> - 4.9.2-4
- Rebuilt for Fedora 22 and 23
- Ada support cannot be built using GCC 5, so we disable it until GCC 5
  become a stable release.

* Fri Jan 02 2015 Ting-Wei Lan <lantw44@gmail.com> - 4.9.2-3
- Enable Ada support on Fedora 21 or later.

- Disable automatic requirements finding in %{cross_sysroot} instead of
  disabling it in all directories.
- Remove the %{cross_triplet}-kernel-headers dependency. It should be pulled
  in by %{cross_triplet}-glibc or %{cross_triplet}-glibc-headers.

* Fri Dec 19 2014 Ting-Wei Lan <lantw44@gmail.com> - 4.9.2-1
- Initial packaging
