+<h2>Shared library numbering</h2>
+<p>
+Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix)
+shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx).
+Bumping the shared library version to 2.x would cause linking problems
+with existing OpenGL applications. Since OpenGL 2.x is backward
+compatible with OpenGL 1.x the shared library version number doesn't
+have to be incremented (which would indicate an incompatible ABI).
+</p>
+<p>
+Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
+for the same reason.
+</p>
+
+
+
<h2>New features</h2>
<ul>
+<li>OpenGL 2.0 and 2.1 API support.
+<li>Entirely new Shading Language code generator. See the
+<a href="shading.html">Shading Language</a> page for more information.
+<li>Much faster software execution of vertex, fragment shaders.
+<li>New vertex buffer object (vbo) infrastructure
<li>Updated glext.h file (version 39)
-<li>Updated glxext.h file (version 18)
+<li>Updated glxext.h file (version 19)
+<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_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
+<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
+<li>Assorted DRI driver bug fixes.
+<li>Fixed a number of bugs that prevented "depth-peeling" rendering from working.
</ul>
<h2>Internal code changes</h2>
-
<ul>
-<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.
+<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>
<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>
