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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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