 790 that seem to be... yes, I've just received confirmation from the beta center, they
 791 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks

 795 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
 796 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
 797 <p>I've been working on Mesa in my spare time for over five years. With Precision
 798 Insight I now have the opportunity to devote my full attention to advancing Mesa
 799 and OpenGL on Linux.</p>
 800 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
 801 my work will continue to be open sourced and available to any other programmers who
 802 may want to contribute to it, or use it for other projects or platforms</p>
 803 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>
 804 <p>
 805 </p><h2>August 23, 1999</h2>
 806 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
 807 Note that this is a new archive, so you will need to re-checkout the archive. That
 808 means don't <i>cvs update</i> from a previous download.</p>

 839 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 840 US$10,000 to the Mesa project to support its continuing development.
 841 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 842 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 843
 844 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 845 improve performance on 3d hardware.  Thanks to Keith's work, many
 846 applications using Mesa 3.1 will see a dramatic performance increase
 847 over Mesa 3.0.  The donation will allow Keith to continue working on
 848 Mesa full time for some time to come.

 855 This donation from John/id is very generous.  Keith and I are very
 856 grateful.
