  22 <h2>March 26, 2007</h2>
  23 <p>
  24 The new Shading Language compiler branch has been merged into the git
  25 master branch.  This is a step toward hardware support for the OpenGL
  26 2.0 Shading Language and will be included in the next Mesa release.
  27 In conjunction, <a href="http://glean.sf.net" target="_parent">Glean
  28 </a> has been updated with a new test that does over 130 tests of the
  29 shading language and built-in functions.

1063 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1064 US$10,000 to the Mesa project to support its continuing development.
1065 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1066 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1067
1068 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1069 improve performance on 3d hardware.  Thanks to Keith's work, many
1070 applications using Mesa 3.1 will see a dramatic performance increase
1071 over Mesa 3.0.  The donation will allow Keith to continue working on
