%changelog
* Tue Apr 20 2020 Mihai Vultur <xanto@egaming.ro>
- Enable vulkan-device-select-layer.

* Sun Feb 09 2020 Mihai Vultur <xanto@egaming.ro>
- Enable zink.

* Sat Feb 08 2020 Mikhail Gavrilov <mikhail.v.gavrilov@gmail.com>
- Prevent radeonsi crashing when compiled with GCC10 on Rawhide.

* Thu Jan 23 2020 Tom Stellard <tstellar@redhat.com>
- Link against libclang-cpp.so
- https://fedoraproject.org/wiki/Changes/Stop-Shipping-Individual-Component-Libraries-In-clang-lib-Package

* Sat Dec 14 2019 Mihai Vultur <xanto@egaming.ro>
- new mesa-overlay-control.py script added to the install list

* Sun Nov 03 2019 Peter Robinson <pbrobinson@gmail.com>
- adjust mesa-khr-devel requires now provided by libglvnd

* Sun Oct 06 2019 Mihai Vultur <xanto@egaming.ro>
- Architecture specific builds might run asynchronous.
- This might cause that same package build for x86_64 will be different when
-  built for i686. This is problematic when we want to install multilib packages. 
- Convert the specfile to template and use it to generate the actual script.
- This will prevent the random failues and mismatch between arch versions.

* Sun Sep 08 2019 Mihai Vultur <xanto@egaming.ro>
- Merge the two implementations.

* Sun Jul 07 2019 Mihai Vultur <xanto@egaming.ro>
- Implement some version autodetection to reduce maintenance work.

* Thu Jul 04 2019 Mihai Vultur <xanto@egaming.ro>
- Modified to point to Valve's Radeon ACO compiler patches from https://github.com/daniel-schuermann/mesa.

* Mon Oct 10 2016 Rudolf Kastl <rudolf@redhat.com>
- Synced with Leighs spec.
