+
+<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>
+
+
