%changelog
* Thu Nov 3 2005 Mike A. Harris <mharris@redhat.com> 6.4-4
- Wrote redhat-mesa-source-filelist-generator to dynamically generate the
  files to be included in the mesa-source subpackage, to minimize future
  maintenance.
- Fixed detection and renaming of software mesa .so version.

* Wed Nov 2 2005 Mike A. Harris <mharris@redhat.com> 6.4-3
- Hack: autodetect if libGL was given .so.1.5* and rename it to 1.2 for
  consistency on all architectures, and to avoid upgrade problems if we
  ever disable DRI on an arch and then re-enable it later.

* Wed Nov 2 2005 Mike A. Harris <mharris@redhat.com> 6.4-2
- Added mesa-6.4-multilib-fix.patch to instrument and attempt to fix Mesa
  bin/installmesa script to work properly with multilib lib64 architectures.
- Set and export LIB_DIR and INCLUDE_DIR in spec file 'install' section,
  and invoke our modified bin/installmesa directly instead of using
  "make install".
- Remove "include/GL/uglglutshapes.h", as it uses the GLUT license, and seems
  like an extraneous file anyway.
- Conditionalize the file manifest to include libGL.so.1.2 on DRI enabled
  builds, but use libGL.so.1.5.060400 instead on DRI disabled builds, as
  this is how upstream builds the library, although it is not clear to me
  why this difference exists yet (which was not in Xorg 6.8.2 Mesa).

* Thu Oct 27 2005 Mike A. Harris <mharris@redhat.com> 6.4-1
- Updated to new upstream MesaLib-6.4
- Updated libGLU.so.1.3.060400 entry in file manifest
- Updated "BuildRequires: libdrm-devel >= 1.0.5" to pick up fixes for the
  unichrome driver.

* Tue Sep 13 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-6
- Fix redhat-mesa-driver-install and spec file to work right on multilib
  systems.
  
* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-5
- Fix mesa-libGL-devel to depend on mesa-libGL instead of mesa-libGLU.
- Added virtual "Provides: libGL..." entries for each subpackage as relevant.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-4
- Added the mesa-source subpackage, which contains part of the Mesa source
  code needed by other packages such as the X server to build stuff.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-3
- Added Conflicts/Obsoletes lines to all of the subpackages to make upgrades
  from previous OS releases, and piecemeal upgrades work as nicely as
  possible.

* Mon Sep 5 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-2
- Wrote redhat-mesa-target script to simplify mesa build target selection.
- Wrote redhat-mesa-driver-install to install the DRI drivers and simplify
  per-arch conditionalization, etc.

* Sun Sep 4 2005 Mike A. Harris <mharris@redhat.com> 6.3.2-1
- Initial build.
