  965. 	</ul>

  966. 	Changes:

  967. 	<ul>

  970. </ul>

  971. 

  972. <p>Please report any problems with this release ASAP. Bugs should be filed on the

  985. <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>

  986. and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,

  987. that seem to be... yes, I've just received confirmation from the beta center, they

  988. are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks

  992. <p>I'm pleased to announce that I've accepted a position with Precision Insight,

  993. Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>

  994. <p>I've been working on Mesa in my spare time for over five years. With Precision

  995. Insight I now have the opportunity to devote my full attention to advancing Mesa

  996. and OpenGL on Linux.</p>

  997. <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,

  998. my work will continue to be open sourced and available to any other programmers who

  999. may want to contribute to it, or use it for other projects or platforms</p>

  1000. <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

  1003. <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.

  1004. Note that this is a new archive, so you will need to re-checkout the archive. That

  1005. means don't <i>cvs update</i> from a previous download.</p>

  1036. <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of

  1037. US$10,000 to the Mesa project to support its continuing development.

  1038. Mesa is a free implementation of the OpenGL 3D graphics library and id's

  1039. newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.

  1040. 

  1041. The donation will go to Keith Whitwell, who has been optimizing Mesa to

  1042. improve performance on 3d hardware.  Thanks to Keith's work, many

  1043. applications using Mesa 3.1 will see a dramatic performance increase

  1044. over Mesa 3.0.  The donation will allow Keith to continue working on

  1045. Mesa full time for some time to come.

  1046. 

  1047. For more information about Mesa see www.mesa3d.org.  For more

  1048. information about id Software, Inc. see www.idsoftware.com.

  1050. --------------------------------

  1051. 

  1052. This donation from John/id is very generous.  Keith and I are very

  1053. grateful.
