1211 that seem to be... yes, I've just received confirmation from the beta center, they
1212 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1213 Keith Whitwell for preparing these for us during Brian's absence.</p>

1216 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1217 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1218 <p>I've been working on Mesa in my spare time for over five years. With Precision
1219 Insight I now have the opportunity to devote my full attention to advancing Mesa
1220 and OpenGL on Linux.</p>
1221 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1222 my work will continue to be open sourced and available to any other programmers who
1223 may want to contribute to it, or use it for other projects or platforms</p>
1224 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1227 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1228 Note that this is a new archive, so you will need to re-checkout the archive. That
1229 means don't <i>cvs update</i> from a previous download.</p>

1252 If you are into the quake scene, you may want to try this out, as it contains some
1253 optimizations specifically in the Q3A rendering path.

1260 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1261 US$10,000 to the Mesa project to support its continuing development.
1262 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1263 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1264
1265 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1266 improve performance on 3d hardware.  Thanks to Keith's work, many
1267 applications using Mesa 3.1 will see a dramatic performance increase
1268 over Mesa 3.0.  The donation will allow Keith to continue working on
1269 Mesa full time for some time to come.
1270

1272 information about id Software, Inc. see www.idsoftware.com.

1276 This donation from John/id is very generous.  Keith and I are very
1277 grateful.
