 <h2>New Features</h2>
 <ul>
 <li>Intel i965 "broadwater" DRI driver

 <li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
 	arrays in an object.

 <li>GL_EXT_texture_sRGB - non-linearly mapped texture formats

 <li>GL_EXT_gpu_program_parameters - addes a few new functions for setting
 	multiple vertex/fragment program parameters with one call.
 <li>"engine" demo
 <li>updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
 <li>many updates to the DRI drivers
 </ul>

 <h2>Changes</h2>
 <ul>
 <li>The glVertexAttribARB functions no longer alias the conventional
 	vertex attributes.
 <li>glxinfo program prints more info with -l option
 <li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
 	compatible, in terms of glBindProgramARB()
 <li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now
 	accepted by the parser, even though the	GL_ARB_vertex_blend and
 	GL_EXT_vertex_weighting extensions aren't supported.
 	Allows Warcraft to run.
 </ul>

 <h2>Bug fixes</h2>
 <ul>
 <li>fixed broken texture border handling for depth textures (bug 6498)
 <li>removed the test for duplicated framebuffer attachments, per
 	version 117 of the GL_EXT_framebuffer_object specification
 <li>fixed a few render-to-texture bugs, including render to depth texture
 <li>clipping of lines against user-defined clip planes was broken (6512)
 <li>assembly language dispatch for SPARC was broken (bug 6484)
 <li>assorted compilation fixes on various Unix platforms (Dan Schikore)
 <li>glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
 <li>assorted minor fixes for 16 and 32 bit/channel modes
 <li>fixed assorted bugs in texture compression paths
 <li>fixed indirect rendering vertex array crashes (bug 6863)
 <li>glDrawPixels GL_INDEX_OFFSET didn't always work
 <li>fixed convolution memory leak (bug 7077)
 <li>rectangular depth textures didn't work
 <li>invalid mode to glBegin didn't generate an error (bug 7142)
 <li>'normalized' parameter to glVertexAttribPointerARB didn't work
 <li>disable bogus GLX_SGI_video_sync extension in xlib driver
 <li>fixed R128 driver locking bug (Martijn van Oosterhout)
 <li>using evaluators with vertex programs caused crashes (bug 7564)
 <li>fragment.position wasn't set correctly for point/line primitives
 <li>fixed parser bug for scalar sources for GL_NV_fragment_program
 <li>max fragment program length was incorrectly 128, now 1024
 <li>writes to result.depth in fragment programs weren't clamped to [0,1]
 <li>fixed potential dangling pointer bug in glBindProgram()
 <li>fixed some memory leaks (and potential crashes) in Xlib driver
 <li>fixed a number of build issues on HP-UX (Christopher Bell)
 <li>accum buffer didn't work with OSMesa interface
 </ul>


 <h2>Internal code changes</h2>

 <p>
 A number of Mesa program-related structs were renamed.
 For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
 All the effected drivers have been updated.
 </p>

 <p>Ian Romanick updated the GL API dispatch code in a number of ways.
 First, many old/unused extensions were removed.
 Second, the static entrypoints for some extensions were removed.
 This means GL function pointers will have to be used more often
 (e.g. use glXGetProcAddressARB()).
 </p>


 <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>
