  39. <h2>New Features</h2>
  40. <ul>
  41. <li>Intel i965 "broadwater" DRI driver
  42.  
  43. <li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
  44.         arrays in an object.
  45.  
  46. <li>GL_EXT_texture_sRGB - non-linearly mapped texture formats
  47.  
  48. <li>GL_EXT_gpu_program_parameters - addes a few new functions for setting
  49.         multiple vertex/fragment program parameters with one call.
  50. <li>"engine" demo
  51. <li>updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
  52. <li>many updates to the DRI drivers
  53. </ul>
  54.  
  55. <h2>Changes</h2>
  56. <ul>
  57. <li>The glVertexAttribARB functions no longer alias the conventional
  58.         vertex attributes.
  59. <li>glxinfo program prints more info with -l option
  60. <li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
  61.         compatible, in terms of glBindProgramARB()
  62. <li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now
  63.         accepted by the parser, even though the GL_ARB_vertex_blend and
  64.         GL_EXT_vertex_weighting extensions aren't supported.
  65.         Allows Warcraft to run.
  66. </ul>
  67.  
  68. <h2>Bug fixes</h2>
  69. <ul>
  70. <li>fixed broken texture border handling for depth textures (bug 6498)
  71. <li>removed the test for duplicated framebuffer attachments, per
  72.         version 117 of the GL_EXT_framebuffer_object specification
  73. <li>fixed a few render-to-texture bugs, including render to depth texture
  74. <li>clipping of lines against user-defined clip planes was broken (6512)
  75. <li>assembly language dispatch for SPARC was broken (bug 6484)
  76. <li>assorted compilation fixes on various Unix platforms (Dan Schikore)
  77. <li>glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
  78. <li>assorted minor fixes for 16 and 32 bit/channel modes
  79. <li>fixed assorted bugs in texture compression paths
  80. <li>fixed indirect rendering vertex array crashes (bug 6863)
  81. <li>glDrawPixels GL_INDEX_OFFSET didn't always work
  82. <li>fixed convolution memory leak (bug 7077)
  83. <li>rectangular depth textures didn't work
  84. <li>invalid mode to glBegin didn't generate an error (bug 7142)
  85. <li>'normalized' parameter to glVertexAttribPointerARB didn't work
  86. <li>disable bogus GLX_SGI_video_sync extension in xlib driver
  87. <li>fixed R128 driver locking bug (Martijn van Oosterhout)
  88. <li>using evaluators with vertex programs caused crashes (bug 7564)
  89. <li>fragment.position wasn't set correctly for point/line primitives
  90. <li>fixed parser bug for scalar sources for GL_NV_fragment_program
  91. <li>max fragment program length was incorrectly 128, now 1024
  92. <li>writes to result.depth in fragment programs weren't clamped to [0,1]
  93. <li>fixed potential dangling pointer bug in glBindProgram()
  94. <li>fixed some memory leaks (and potential crashes) in Xlib driver
  95. <li>fixed a number of build issues on HP-UX (Christopher Bell)
  96. <li>accum buffer didn't work with OSMesa interface
  97. </ul>
  98.  
  99.  
  100. <h2>Internal code changes</h2>
  101.  
  102. <p>
  103. A number of Mesa program-related structs were renamed.
  104. For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
  105. All the effected drivers have been updated.
  106. </p>
  107.  
  108. <p>Ian Romanick updated the GL API dispatch code in a number of ways.
  109. First, many old/unused extensions were removed.
  110. Second, the static entrypoints for some extensions were removed.
  111. This means GL function pointers will have to be used more often
  112. (e.g. use glXGetProcAddressARB()).
  113. </p>
  114.  
  115.  
  116. <h2>To Do (someday) items</h2>
  117. <ul>
  118. <li>Switch to freeglut
  119. <li>Increase MAX_DRAWBUFFERS
  120. <li>Fix linux-glide target/driver.
  121. <li>Fix lambda calculation for frag progs.
  122. </ul>
  123.
