  67 <p>
  68 Mesa's directory tree has been overhauled.
  69 Things are better organized now with some thought toward future needs.
  70 </p>
  71 <p>
  72 In CVS, the latest Mesa 5.1 development code is now rooted under the
  73 <b>Mesa-newtree/</b> directory.  The old top-level <b>Mesa/</b> directory
  74 holds the Mesa 5.0.x code which will be abandoned at some point.

 634 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 635 US$10,000 to the Mesa project to support its continuing development.
 636 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 637 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 638
 639 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 640 improve performance on 3d hardware.  Thanks to Keith's work, many
 641 applications using Mesa 3.1 will see a dramatic performance increase
 642 over Mesa 3.0.  The donation will allow Keith to continue working on
 643 Mesa full time for some time to come.
