  32 <h2>New Features</h2>
  33 <ul>
  34 <li>Intel i965 "broadwater" DRI driver
  35
  36 <li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
  37         arrays in an object.
  38
  39 <li>GL_EXT_texture_sRGB - non-linearly mapped texture formats
  40
  41 <li>GL_EXT_gpu_program_parameters - addes a few new functions for setting
  42         multiple vertex/fragment program parameters with one call.
  43 <li>"engine" demo
  44 <li>updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
  45 <li>many updates to the DRI drivers
  46 </ul>
  47
  48 <h2>Changes</h2>
  49 <ul>
  50 <li>The glVertexAttribARB functions no longer alias the conventional
  51         vertex attributes.
  52 <li>glxinfo program prints more info with -l option
  53 <li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
  54         compatible, in terms of glBindProgramARB()
  55 <li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now
  56         accepted by the parser, even though the GL_ARB_vertex_blend and
  57         GL_EXT_vertex_weighting extensions aren't supported.
  58         Allows Warcraft to run.
  59 </ul>
  60
  61 <h2>Bug fixes</h2>
  62 <ul>
  63 <li>fixed broken texture border handling for depth textures (bug 6498)
  64 <li>removed the test for duplicated framebuffer attachments, per
  65         version 117 of the GL_EXT_framebuffer_object specification
  66 <li>fixed a few render-to-texture bugs, including render to depth texture
  67 <li>clipping of lines against user-defined clip planes was broken (6512)
  68 <li>assembly language dispatch for SPARC was broken (bug 6484)
  69 <li>assorted compilation fixes on various Unix platforms (Dan Schikore)
  70 <li>glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
  71 <li>assorted minor fixes for 16 and 32 bit/channel modes
  72 <li>fixed assorted bugs in texture compression paths
  73 <li>fixed indirect rendering vertex array crashes (bug 6863)
  74 <li>glDrawPixels GL_INDEX_OFFSET didn't always work
  75 <li>fixed convolution memory leak (bug 7077)
  76 <li>rectangular depth textures didn't work
  77 <li>invalid mode to glBegin didn't generate an error (bug 7142)
  78 <li>'normalized' parameter to glVertexAttribPointerARB didn't work
  79 <li>disable bogus GLX_SGI_video_sync extension in xlib driver
  80 <li>fixed R128 driver locking bug (Martijn van Oosterhout)
  81 <li>using evaluators with vertex programs caused crashes (bug 7564)
  82 <li>fragment.position wasn't set correctly for point/line primitives
  83 <li>fixed parser bug for scalar sources for GL_NV_fragment_program
  84 <li>max fragment program length was incorrectly 128, now 1024
  85 <li>writes to result.depth in fragment programs weren't clamped to [0,1]
  86 <li>fixed potential dangling pointer bug in glBindProgram()
  87 <li>fixed some memory leaks (and potential crashes) in Xlib driver
  88 <li>fixed a number of build issues on HP-UX (Christopher Bell)
  89 <li>accum buffer didn't work with OSMesa interface
  90 </ul>
  91
  92
  93 <h2>Internal code changes</h2>
  94
  95 <p>
  96 A number of Mesa program-related structs were renamed.
  97 For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
  98 All the effected drivers have been updated.
  99 </p>
 100
 101 <p>Ian Romanick updated the GL API dispatch code in a number of ways.
 102 First, many old/unused extensions were removed.
 103 Second, the static entrypoints for some extensions were removed.
 104 This means GL function pointers will have to be used more often
 105 (e.g. use glXGetProcAddressARB()).
 106 </p>
 107
 108
 109 <h2>To Do (someday) items</h2>
 110 <ul>
 111 <li>Switch to freeglut
 112 <li>Increase MAX_DRAWBUFFERS
 113 <li>Fix linux-glide target/driver.
 114 <li>Fix lambda calculation for frag progs.
 115 </ul>
