+<h2>New Features</h2>
+<ul>
+<li>OpenGL Shading language support
+<br>
+ This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
+ GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of
+ the work was done by Michal Krol.
+ There's probably a fair number of bugs since this is a pretty large,
+ complicated body of code.
+<br>
+ The OpenGL 2.0 interface to these features will be implemented in a
+ future version of Mesa,
+
+<li>GL_EXT_timer_query
+<br>
+ Used to measure the time of OpenGL operations at high precision.
+ Only supported in the software/Xlib driver at this time.
+
+<li>GL_EXT_packed_depth_stencil
+<br>
+ Defines a new GL_DEPTH_STENCIL_EXT pixel format.
+
+<li>GL_EXT_framebuffer_blit
+<br>
+ A simplified glCopyPixels-like feature for copying pixel rectangles.
+
+<li>GL_ARB_half_float_pixel
+<br>
+ Adds a new half-precision floating point format for image transfers,
+ such as for glDrawPixels, glReadPixels, glTexImage, etc.
+</ul>
+
+<h2>Changes</h2>
+<ul>
+<li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
+<li>removed GL_SGIX/SGIS_pixel_texture extensions
+</ul>
+<h2>Bug fixes</h2>
+<ul>
+<li>fixed glxcontextmodes.c datatype problem (bug 5835)
+<li>fixed aix-gcc build/install bugs (bug 5874)
+<li>fixed some bugs in texture env program generation
+<li>glXCopyContext() didn't handle texture object bindings properly
+<li>glXCopyContext() didn't copy all lighting state
+<li>fixed FreeBSD config (Pedro Giffuni)
+<li>fixed some minor framebuffer object bugs
+<li>replaced dprintf() with _glu_printf() in GLU (bug 6244)
+<li>fixed a number of thread safety bugs/regressions
+<li>fixed a number of GLU tesselator bugs (John Shell, bug 6339)
+<li>paletted texturing was broken w/ floating point palettes (K. Schultz)
+<li>lots of assorted framebuffer object bug fixes
+</ul>
+
+
+<h2>Known Issues</h2>
+<ul>
+<li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL
+textures should work.
+</ul>
+
+
+<h2>Driver Interface Changes</h2>
+<ul>
+<li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
+the two-sided versions: Driver.Stencil*Separate().
+<li>Render-to-texture: The functions for rendering to textures have changed.
+</ul>
+
+
+<h2>To Do (someday) items</h2>
+<ul>
+<li>Switch to freeglut
+<li>Increase MAX_DRAWBUFFERS
+<li>Fix linux-glide target/driver.
+<li>Fix lambda calculation for frag progs.
+</ul>
+
