33 <h2>New Features</h2>
34 <ul>
35 <li>Intel i965 "broadwater" DRI driver
37 <li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
38 arrays in an object.
40 <li>GL_EXT_texture_sRGB - non-linearly mapped texture formats
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>
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>
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>
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>
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>
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>
