22New Features
23------------
24
25-  Intel i965 "broadwater" DRI driver
26-  GL_APPLE_vertex_array_object - allows encapsulation of a set of
27   vertex arrays in an object.
28-  GL_EXT_texture_sRGB - non-linearly mapped texture formats
29-  GL_EXT_gpu_program_parameters - addes a few new functions for setting
30   multiple vertex/fragment program parameters with one call.
31-  "engine" demo
32-  updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
33-  many updates to the DRI drivers
34
35Changes
36-------
37
38-  The glVertexAttribARB functions no longer alias the conventional
39   vertex attributes.
40-  glxinfo program prints more info with -l option
41-  GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
42   compatible, in terms of glBindProgramARB()
43-  The GL_ARB_vertex_program attribute ``vertex.weight`` is now accepted
44   by the parser, even though the GL_ARB_vertex_blend and
45   GL_EXT_vertex_weighting extensions aren't supported. Allows Warcraft
46   to run.
47
48Bug fixes
49---------
50
51-  fixed broken texture border handling for depth textures (bug 6498)
52-  removed the test for duplicated framebuffer attachments, per version
53   117 of the GL_EXT_framebuffer_object specification
54-  fixed a few render-to-texture bugs, including render to depth texture
55-  clipping of lines against user-defined clip planes was broken (6512)
56-  assembly language dispatch for SPARC was broken (bug 6484)
57-  assorted compilation fixes on various Unix platforms (Dan Schikore)
58-  glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
59-  assorted minor fixes for 16 and 32 bit/channel modes
60-  fixed assorted bugs in texture compression paths
61-  fixed indirect rendering vertex array crashes (bug 6863)
62-  glDrawPixels GL_INDEX_OFFSET didn't always work
63-  fixed convolution memory leak (bug 7077)
64-  rectangular depth textures didn't work
65-  invalid mode to glBegin didn't generate an error (bug 7142)
66-  'normalized' parameter to glVertexAttribPointerARB didn't work
67-  disable bogus GLX_SGI_video_sync extension in xlib driver
68-  fixed R128 driver locking bug (Martijn van Oosterhout)
69-  using evaluators with vertex programs caused crashes (bug 7564)
70-  fragment.position wasn't set correctly for point/line primitives
71-  fixed parser bug for scalar sources for GL_NV_fragment_program
72-  max fragment program length was incorrectly 128, now 1024
73-  writes to result.depth in fragment programs weren't clamped to [0,1]
74-  fixed potential dangling pointer bug in glBindProgram()
75-  fixed some memory leaks (and potential crashes) in Xlib driver
76-  fixed a number of build issues on HP-UX (Christopher Bell)
77-  accum buffer didn't work with OSMesa interface
78
79Internal code changes
80---------------------
81
82A number of Mesa program-related structs were renamed. For example
83*struct vertex_program* is now *struct gl_vertex_program*. All the
84effected drivers have been updated.
85
86Ian Romanick updated the GL API dispatch code in a number of ways.
87First, many old/unused extensions were removed. Second, the static
88entrypoints for some extensions were removed. This means GL function
89pointers will have to be used more often (e.g. use
90glXGetProcAddressARB()).
91
92To Do (someday) items
93---------------------
94
95-  Switch to freeglut
96-  Increase MAX_DRAWBUFFERS
97-  Fix linux-glide target/driver.
98-  Fix lambda calculation for frag progs.
