 <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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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>
