486 - glXCopyContext's mask parameter is now unsigned long, per GLX spec
487 </ul>
488</ul>
489
490<p>Please report any problems with this release ASAP. Bugs should be filed on the
491Mesa3D website at sourceforge.<br>
492After 3.2 is wrapped up I hope to release 3.3 beta 1 soon afterward.</p>

510<p>I'm pleased to announce that I've accepted a position with Precision Insight,
511Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
512<p>I've been working on Mesa in my spare time for over five years. With Precision
513Insight I now have the opportunity to devote my full attention to advancing Mesa
514and OpenGL on Linux.</p>
515<p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
516my work will continue to be open sourced and available to any other programmers who
517may want to contribute to it, or use it for other projects or platforms</p>
518<p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

554<pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
555US$10,000 to the Mesa project to support its continuing development.
556Mesa is a free implementation of the OpenGL 3D graphics library and id's
557newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
558
559The donation will go to Keith Whitwell, who has been optimizing Mesa to
560improve performance on 3d hardware. Thanks to Keith's work, many
561applications using Mesa 3.1 will see a dramatic performance increase
562over Mesa 3.0. The donation will allow Keith to continue working on
563Mesa full time for some time to come.
564

566information about id Software, Inc. see www.idsoftware.com.

571grateful.
