 735 that seem to be... yes, I've just received confirmation from the beta center, they
 736 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
 737 Keith Whitwell for preparing these for us during Brian's absence.</p>

 740 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
 741 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
 742 <p>I've been working on Mesa in my spare time for over five years. With Precision
 743 Insight I now have the opportunity to devote my full attention to advancing Mesa
 744 and OpenGL on Linux.</p>
 745 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
 746 my work will continue to be open sourced and available to any other programmers who
 747 may want to contribute to it, or use it for other projects or platforms</p>
 748 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

 751 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
 752 Note that this is a new archive, so you will need to re-checkout the archive. That
 753 means don't <i>cvs update</i> from a previous download.</p>

 784 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 785 US$10,000 to the Mesa project to support its continuing development.
 786 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 787 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 788
 789 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 790 improve performance on 3d hardware.  Thanks to Keith's work, many
 791 applications using Mesa 3.1 will see a dramatic performance increase
 792 over Mesa 3.0.  The donation will allow Keith to continue working on
 793 Mesa full time for some time to come.
 794
