 100 Gallium3D is the codename for the new Mesa device driver architecture
 101 which is currently under development.
 102 A <a href="http://wiki.freedesktop.org/wiki/Software/gallium"
 103 target="_parent"> summary</a> of the architecture can be found on the
 104 Tungsten Graphics website.
 105 </p>
 106 <p>
 107 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
 108 of the git repository.
 109 Currently, there's only a software-only driver and an Intel i915/945 driver
 110 but other drivers will be coming...

1120 <p>Please report any problems with this release ASAP. Bugs should be filed on the
1121 Mesa3D website at sourceforge.<br>
1122 After 3.2 is wrapped up I hope to release 3.3 beta 1 soon afterward.</p>

1133 <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>
1134 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1135 that seem to be... yes, I've just received confirmation from the beta center, they
1136 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1137 Keith Whitwell for preparing these for us during Brian's absence.</p>

1140 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1141 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1142 <p>I've been working on Mesa in my spare time for over five years. With Precision
1143 Insight I now have the opportunity to devote my full attention to advancing Mesa
1144 and OpenGL on Linux.</p>
1145 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1146 my work will continue to be open sourced and available to any other programmers who
1147 may want to contribute to it, or use it for other projects or platforms</p>
1148 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1151 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1152 Note that this is a new archive, so you will need to re-checkout the archive. That
1153 means don't <i>cvs update</i> from a previous download.</p>

1176 If you are into the quake scene, you may want to try this out, as it contains some
1177 optimizations specifically in the Q3A rendering path.

1184 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1185 US$10,000 to the Mesa project to support its continuing development.
1186 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1187 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1188
1189 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1190 improve performance on 3d hardware.  Thanks to Keith's work, many
1191 applications using Mesa 3.1 will see a dramatic performance increase
1192 over Mesa 3.0.  The donation will allow Keith to continue working on
1193 Mesa full time for some time to come.
1194

1196 information about id Software, Inc. see www.idsoftware.com.
