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>
97A number of Mesa program-related structs were renamed.
98For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
99All the effected drivers have been updated.
100</p>
101
102<p>Ian Romanick updated the GL API dispatch code in a number of ways.
103First, many old/unused extensions were removed.
104Second, the static entrypoints for some extensions were removed.
105This 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>
