<H1>Mesa 6.5.3 Release Notes / (in progress)</H1>

<p>
Mesa 6.5.3 is a 6.5 follow-on development release with many internal changes.
</p>


<h2>MD5 checksums</h2>
<pre>
TBD
</pre>


<h2>New features</h2>
<ul>
<li>OpenGL 2.0 support.
<li>Entirely new Shading Language code generator.
<li>Much faster software execution of vertex, fragment shaders.
<li>New vertex buffer object infrastructure (replaces old array_cache code).
<li>Updated glext.h file (version 39)
<li>Updated glxext.h file (version 18)
<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
    "multiple render targets" are really supported.
</ul>

<h2>Bug fixes</h2>
<ul>
<li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
<li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
<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>


<h2>Internal code changes</h2>

<ul>
<li>Massive changes to the Shading Language compiler.
<li>The _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and
_TnlProgram fields have been moved.
<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.
</ul>


<h2>To Do (someday) items</h2>
<ul>
<li>Switch to freeglut
<li>Fix linux-glide target/driver.
<li>Improved lambda and derivative calculation for frag progs.
</ul>


<h2>Driver Status</h2>
