<H1>Mesa 6.5.3 Release Notes / (in progress)</H1>
<p>
-Mesa 6.5.3 is a 6.5 follow-on development release mostly consisting of
-bug fixes</a>.
+Mesa 6.5.3 is a 6.5 follow-on development release with many internal changes.
</p>
<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>
<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_MAX_DRAWBUFFERS is now 4 (software rendering) so
- "multiple render targets" are really supported.
+<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
+ <li>1D convolution state could effect 2D image transfers
</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->FragmentProgram._Active field has been removed.
<h2>To Do (someday) items</h2>
<ul>
<li>Switch to freeglut
-<li>Increase MAX_DRAWBUFFERS
<li>Fix linux-glide target/driver.
<li>Improved lambda and derivative calculation for frag progs.
</ul>
