  33 <h2>New Features</h2>
  34 <ul>
  35 <li>Intel i965 "broadwater" DRI driver
  36
  37 <li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
  38         arrays in an object.
  39
  40 <li>GL_EXT_texture_sRGB - non-linearly mapped texture formats
  41
  42 <li>GL_EXT_gpu_program_parameters - addes a few new functions for setting
  43         multiple vertex/fragment program parameters with one call.
  44 <li>"engine" demo
  45 <li>updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
  46 <li>many updates to the DRI drivers
  47 </ul>
  48
  49 <h2>Changes</h2>
  50 <ul>
  51 <li>The glVertexAttribARB functions no longer alias the conventional
  52         vertex attributes.
  53 <li>glxinfo program prints more info with -l option
  54 <li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
  55         compatible, in terms of glBindProgramARB()
  56 <li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now
  57         accepted by the parser, even though the GL_ARB_vertex_blend and
  58         GL_EXT_vertex_weighting extensions aren't supported.
  59         Allows Warcraft to run.
  60 </ul>
  61
  62 <h2>Bug fixes</h2>
  63 <ul>
  64 <li>fixed broken texture border handling for depth textures (bug 6498)
  65 <li>removed the test for duplicated framebuffer attachments, per
  66         version 117 of the GL_EXT_framebuffer_object specification
  67 <li>fixed a few render-to-texture bugs, including render to depth texture
  68 <li>clipping of lines against user-defined clip planes was broken (6512)
  69 <li>assembly language dispatch for SPARC was broken (bug 6484)
  70 <li>assorted compilation fixes on various Unix platforms (Dan Schikore)
  71 <li>glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
  72 <li>assorted minor fixes for 16 and 32 bit/channel modes
  73 <li>fixed assorted bugs in texture compression paths
  74 <li>fixed indirect rendering vertex array crashes (bug 6863)
  75 <li>glDrawPixels GL_INDEX_OFFSET didn't always work
  76 <li>fixed convolution memory leak (bug 7077)
  77 <li>rectangular depth textures didn't work
  78 <li>invalid mode to glBegin didn't generate an error (bug 7142)
  79 <li>'normalized' parameter to glVertexAttribPointerARB didn't work
  80 <li>disable bogus GLX_SGI_video_sync extension in xlib driver
  81 <li>fixed R128 driver locking bug (Martijn van Oosterhout)
  82 <li>using evaluators with vertex programs caused crashes (bug 7564)
  83 <li>fragment.position wasn't set correctly for point/line primitives
  84 <li>fixed parser bug for scalar sources for GL_NV_fragment_program
  85 <li>max fragment program length was incorrectly 128, now 1024
  86 <li>writes to result.depth in fragment programs weren't clamped to [0,1]
  87 <li>fixed potential dangling pointer bug in glBindProgram()
  88 <li>fixed some memory leaks (and potential crashes) in Xlib driver
  89 <li>fixed a number of build issues on HP-UX (Christopher Bell)
  90 <li>accum buffer didn't work with OSMesa interface
  91 </ul>

  94 <h2>Internal code changes</h2>
  95
  96 <p>
  97 A number of Mesa program-related structs were renamed.
  98 For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
  99 All the effected drivers have been updated.
 100 </p>
 101
 102 <p>Ian Romanick updated the GL API dispatch code in a number of ways.
 103 First, many old/unused extensions were removed.
 104 Second, the static entrypoints for some extensions were removed.
 105 This means GL function pointers will have to be used more often
 106 (e.g. use glXGetProcAddressARB()).
 107 </p>
 108
 109
 110 <h2>To Do (someday) items</h2>
 111 <ul>
 112 <li>Switch to freeglut
 113 <li>Increase MAX_DRAWBUFFERS
 114 <li>Fix linux-glide target/driver.
 115 <li>Fix lambda calculation for frag progs.
 116 </ul>
