Mesa 7.4.1 Release Notes / 18 April 2009
========================================

Mesa 7.4.1 is a stable development release fixing bugs since the 7.4
release.

Mesa 7.4.1 implements the OpenGL 2.1 API, but the version reported by
glGetString(GL_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 2.1.

See the :doc:`Compiling/Installing page <../install>` for
prerequisites for DRI hardware acceleration.

Bug fixes
---------

-  Fixed a two-sided lighting bug in fixed-function-to-GPU code
   generation
-  Fixed some Darwin issues (Jeremy Huddleston)
-  Indexing the GLSL gl_EyePlane[] or gl_ObjectPlane[] arrays with a
   variable was broken, bug 20986
-  Fixed incorrect texture unit bias in TXB instruction
-  glTexParameter settings weren't always propogated to drivers
-  Assorted vertex/fragment program bug fixes
-  Fixed point rendering in software rasterizer
-  Fixed potential deadlock in object hash functions
-  Fix a couple bugs surrounding front-buffer rendering with DRI2, but
   this is not quite complete.
-  Fixed glPopAttrib() bug when restoring user clip planes
