1281 Mesa3D website at sourceforge.<br>
1282 After 3.2 is wrapped up I hope to release 3.3 beta 1 soon afterward.</p>

1293 <p>There appear to be two new files on the ftp site, <code>MesaLib-3.1beta3.tar.gz</code>
1294 and <code>MesaDemos-3.1beta3.tar.gz</code>,
1295 that seem to be... yes, I've just received confirmation from the beta center, they
1296 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks

1300 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1301 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1302 <p>I've been working on Mesa in my spare time for over five years. With Precision
1303 Insight I now have the opportunity to devote my full attention to advancing Mesa
1304 and OpenGL on Linux.</p>
1305 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1306 my work will continue to be open sourced and available to any other programmers who
1307 may want to contribute to it, or use it for other projects or platforms</p>
1308 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1343 <h2>May 13, 1999</h2>
1344 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1345 US$10,000 to the Mesa project to support its continuing development.
1346 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1347 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1348
1349 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1350 improve performance on 3d hardware.  Thanks to Keith's work, many
1351 applications using Mesa 3.1 will see a dramatic performance increase
1352 over Mesa 3.0.  The donation will allow Keith to continue working on
1353 Mesa full time for some time to come.
1354
1355 For more information about Mesa see www.mesa3d.org.  For more
1356 information about id Software, Inc. see www.idsoftware.com.

1358 --------------------------------

1360 This donation from John/id is very generous.  Keith and I are very
1361 grateful.
