<H1>Introduction</H1>
<p>
-Mesa is a 3-D graphics library with an API which is very similar to
-that of <a href="http://www.opengl.org/" target="_parent">OpenGL</a>.*
-To the extent that Mesa utilizes the OpenGL command syntax or state
-machine, it is being used with authorization from <a
-href="http://www.sgi.com/" target="_parent">Silicon Graphics,
-Inc.</a>(SGI). However, the author does not possess an OpenGL license
-from SGI, and makes no claim that Mesa is in any way a compatible
-replacement for OpenGL or associated with SGI. Those who want a
-licensed implementation of OpenGL should contact a licensed
-vendor.
+Mesa is an open-source implementation of the
+<a href="http://www.opengl.org/" target="_parent">OpenGL</a> specification -
+a system for rendering interactive 3D graphics.

<p>
-Please do not refer to the library as <em>MesaGL</em> (for legal
-reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
-library</em>. <br>
+A variety of device drivers allows Mesa to be used in many different
+environments ranging from software emulation to complete hardware acceleration
+for modern GPUs.

+Mesa ties into several other open-source projects: the
+<a href="http://dri.sf.net/" target="_parent">Direct Rendering Infrastructure</a>
+and <a href="http://x.org" target="_parent">X.org</a> to provide OpenGL
+support to users of X on Linux, FreeBSD and other operating systems.

+The new Shading Language compiler branch has been merged into the git
+master branch. This is a step toward hardware support for the OpenGL
+2.0 Shading Language and will be included in the next Mesa release.
+In conjunction, <a href="http://glean.sf.net" target="_parent">Glean
+</a> has been updated with a new test that does over 130 tests of the
+shading language and built-in functions.
+</p>
+
+<h2>April 2007</h2>
+<p>
+Thomas Hellström of
+<a href="http://www.tungstengraphics.com" target="_parent">
+Tungsten Graphics</a> has written a whitepaper describing the new
+<a href="http://www.tungstengraphics.com/mm.pdf">DRI memory management
+system</a>.

<h2>December 5, 2006</h2>
<p>
Mesa is now using git as its source code management system.
<li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
<li>1D convolution state could effect 2D image transfers
+<li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
+<li>Fixed a number of framebuffer/renderbuffer reference counting bugs
+<li>Fixed a few bugs in software-emulated alpha planes
</ul>
<li>Massive changes to the Shading Language compiler.
<li>The _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and
_TnlProgram fields have been moved.
-<li>The ctx->FragmentProgram._Active field has been removed.
<li>The ctx->Vertex/FragmentProgram._Current fields point to the program
in effect, whether it comes from a shader, user-program or generated
fixed-function program.
-<li>The _UseTexEnvProgram field has been removed.
</ul>
