<
li>Intel i965
"broadwater" DRI driver
<
li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex
arrays in an object.
<
li>GL_EXT_texture_sRGB - non-linearly mapped texture formats
<
li>GL_EXT_gpu_program_parameters - addes a few new functions
for setting
multiple vertex/fragment program parameters with one call.
<
li>updated fbdev driver and GLUT
for fbdev
(Sean D
'Epagnier)
<li>many updates to the DRI drivers
</ul>
<h2>Changes</h2>
<ul>
<li>The glVertexAttribARB functions no longer alias the conventional
vertex attributes.
<li>glxinfo program prints more info with -l option
<li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
compatible, in terms of glBindProgramARB()
<li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now
accepted by the parser, even though the GL_ARB_vertex_blend and
GL_EXT_vertex_weighting extensions aren't supported.
Allows Warcraft to run.
<
li>fixed broken texture
border handling
for depth textures
(bug
6498)
<
li>removed the test
for duplicated framebuffer attachments, per
version 117 of the GL_EXT_framebuffer_object specification
<
li>fixed a few render-to-texture bugs, including render to depth texture
<
li>clipping of lines against user-defined clip planes was broken
(6512)
<
li>assembly
language dispatch
for SPARC was broken
(bug
6484)
<
li>assorted compilation fixes on various Unix platforms
(Dan Schikore
)
<
li>glPopAttrib could restore an invalid
value for GL_DRAW_BUFFER
<
li>assorted minor fixes
for 16 and
32 bit
/channel modes
<
li>fixed assorted bugs in texture compression paths
<
li>fixed indirect rendering vertex array crashes
(bug
6863)
<
li>glDrawPixels GL_INDEX_OFFSET didn
't always work
<li>fixed convolution memory leak (bug 7077)
<li>rectangular depth textures didn't work
<
li>invalid mode to glBegin didn
't generate an error (bug 7142)
<li>'normalized' parameter to glVertexAttribPointerARB didn't work
<
li>disable bogus GLX_SGI_video_sync extension in xlib driver
<
li>fixed R128 driver locking bug
(Martijn van Oosterhout
)
<
li>using evaluators with vertex programs caused crashes
(bug
7564)
<
li>fragment.position wasn
't set correctly for point/line primitives
<li>fixed parser bug for scalar sources for GL_NV_fragment_program
<li>max fragment program length was incorrectly 128, now 1024
<li>writes to result.depth in fragment programs weren't clamped to [0,1]
<
li>fixed potential dangling pointer bug in glBindProgram
()
<
li>fixed some memory leaks
(and potential crashes
) in Xlib driver
<
li>fixed a number of build issues on HP-UX
(Christopher Bell
)
<
li>accum buffer didn
't work with OSMesa interface
</ul>
<h2>Internal code changes</h2>
<p>
A number of Mesa program-related structs were renamed.
For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
All the effected drivers have been updated.
</p>
<p>Ian Romanick updated the GL API dispatch code in a number of ways.
First, many old/unused extensions were removed.
Second, the static entrypoints for some extensions were removed.
This means GL function pointers will have to be used more often
(e.g. use glXGetProcAddressARB()).
</p>
<h2>To Do (someday) items</h2>
<ul>
<li>Switch to freeglut
<li>Increase MAX_DRAWBUFFERS
<li>Fix linux-glide target/driver.
<li>Fix lambda calculation for frag progs.
</ul>
