New Features

Intel i965 "broadwater" DRI driver - -
GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex - arrays in an object. - -
GL_EXT_texture_sRGB - non-linearly mapped texture formats - -
GL_EXT_gpu_program_parameters - addes a few new functions for setting - multiple vertex/fragment program parameters with one call. -
"engine" demo -
updated fbdev driver and GLUT for fbdev (Sean D'Epagnier) -
many updates to the DRI drivers -

- -

Changes

The glVertexAttribARB functions no longer alias the conventional - vertex attributes. -
glxinfo program prints more info with -l option -
GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now - compatible, in terms of glBindProgramARB() -
The GL_ARB_vertex_program attribute vertex.weight 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. -

- -

Bug fixes

fixed broken texture border handling for depth textures (bug 6498) -
removed the test for duplicated framebuffer attachments, per - version 117 of the GL_EXT_framebuffer_object specification -
fixed a few render-to-texture bugs, including render to depth texture -
clipping of lines against user-defined clip planes was broken (6512) -
assembly language dispatch for SPARC was broken (bug 6484) -
assorted compilation fixes on various Unix platforms (Dan Schikore) -
glPopAttrib could restore an invalid value for GL_DRAW_BUFFER -
assorted minor fixes for 16 and 32 bit/channel modes -
fixed assorted bugs in texture compression paths -
fixed indirect rendering vertex array crashes (bug 6863) -
glDrawPixels GL_INDEX_OFFSET didn't always work -
fixed convolution memory leak (bug 7077) -
rectangular depth textures didn't work -
invalid mode to glBegin didn't generate an error (bug 7142) -
'normalized' parameter to glVertexAttribPointerARB didn't work -
disable bogus GLX_SGI_video_sync extension in xlib driver -
fixed R128 driver locking bug (Martijn van Oosterhout) -
using evaluators with vertex programs caused crashes (bug 7564) -
fragment.position wasn't set correctly for point/line primitives -
fixed parser bug for scalar sources for GL_NV_fragment_program -
max fragment program length was incorrectly 128, now 1024 -
writes to result.depth in fragment programs weren't clamped to [0,1] -
fixed potential dangling pointer bug in glBindProgram() -
fixed some memory leaks (and potential crashes) in Xlib driver -
fixed a number of build issues on HP-UX (Christopher Bell) -
accum buffer didn't work with OSMesa interface -

- - -

Internal code changes

- -

-A number of Mesa program-related structs were renamed. -For example struct vertex_program is now struct gl_vertex_program. -All the effected drivers have been updated. -

- -

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()). -

To Do (someday) items

Fix linux-glide target/driver. -
Fix lambda calculation for frag progs. -
