1201 <p>There appear to be two new files on the ftp site, <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaLib-3.1beta3.tar.gz">MesaLib-3.1beta3.tar.gz</a>
1202 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1203 that seem to be... yes, I've just received confirmation from the beta center, they
1204 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1205 Keith Whitwell for preparing these for us during Brian's absence.</p>

1208 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1209 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1210 <p>I've been working on Mesa in my spare time for over five years. With Precision
1211 Insight I now have the opportunity to devote my full attention to advancing Mesa
1212 and OpenGL on Linux.</p>
1213 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1214 my work will continue to be open sourced and available to any other programmers who
1215 may want to contribute to it, or use it for other projects or platforms</p>
1216 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>
1217 <p>

1219 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1220 Note that this is a new archive, so you will need to re-checkout the archive. That
1221 means don't <i>cvs update</i> from a previous download.</p>
1222 <p>

1244 If you are into the quake scene, you may want to try this out, as it contains some
1245 optimizations specifically in the Q3A rendering path.

1252 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1253 US$10,000 to the Mesa project to support its continuing development.
1254 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1255 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1256
1257 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1258 improve performance on 3d hardware.  Thanks to Keith's work, many
1259 applications using Mesa 3.1 will see a dramatic performance increase
1260 over Mesa 3.0.  The donation will allow Keith to continue working on
1261 Mesa full time for some time to come.
1262
1263 For more information about Mesa see www.mesa3d.org.  For more
1264 information about id Software, Inc. see www.idsoftware.com.

1268 This donation from John/id is very generous.  Keith and I are very
1269 grateful.
