-<H1>Mesa 6.5.3 Release Notes / (in progress)</H1>
+<H1>Mesa 6.5.3 Release Notes / April ??, 2007</H1>
<p>
-Mesa 6.5.3 is a 6.5 follow-on development release with many internal changes.
+Mesa 6.5.3 is a development release with many changes and new features.
+Mesa 7.0 is expected to follow shortly.
</p>
<h2>New features</h2>
<ul>
-<li>OpenGL 2.0 support.
+<li>OpenGL 2.0 and 2.1 API 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>New vertex buffer object (vbo) infrastructure
<li>Updated glext.h file (version 39)
<li>Updated glxext.h file (version 18)
<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
<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
+<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
+<li>Assorted DRI driver bug fixes.
</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.
+<li>Old array_cache module replaced by new vbo module. All geometry
+rendering is now cast in the form of vertex buffer objects.
+<li>Massive changes to the Shading Language compiler and related state.
+<li>Vertex/fragment shaders are compiled into GPU instructions and
+programs very similar to GL_ARB_vertex/fragment_program.
+<li>Vertex and fragment programs are executed with the same code now.
+<li>The SSE-optimized vertex program path has been removed since it didn't
+support more than 12 temp registers, didn't support branching/looping, etc.
</ul>
