New features

New DRI memory manager system. Currently used by the i915tex driver. +Other DRI drivers will be updated to use the new memory manager in coming +months. +
+To use the new driver you'll need the most recent DRM library and drivers +(version 2.2 or later) and a recent xf86-video-intel driver module from X.org. +
+New features resulting from this work include: +
- EXT_framebuffer_objects, render to texture +
- ARB_pixel_buffer_objects +
- Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels +
- Accelerated texture uploads from pixel buffer objects +
- Potentially texturing directly from the pixel buffer object (zero +copy texturing). +
+
New Intel i965 DRI driver +
New minstall script to replace normal install program +
Faster fragment program execution in software +
Added (or fixed) support for + GLX_SGI_make_current_read to the following drivers: +
- radeon
- savage
- mga
- tdfx
+
Added support for ARB_occlusion_query to the tdfx driver (Ian +Romanick).

+ +

Bug fixes

fixed invalid memory read while rendering textured points (bug 8320) +
fixed problems with freebsd-dri configuration (bug 8344) +
Mesa's fake glxGetCurrentContext() wasn't thread-aware +
OPTION NV_position_invariant didn't work in NV vertex programs +
glDrawPixels into a user-created framebuffer object could crash Xlib driver +
Line clipping was broken in some circumstances +
fragment.fogcoord register didn't always contain the correct value +
RGBA logicops didn't work reliably in some DRI drivers +
Fixed broken RGBA LogicOps in Intel DRI drivers +
Fixed some fragment program bugs in Intel i915 DRI driver +
Fixed glGetVertexAttribfvARB bug 8883 +
Implemented glGetUniform[fi]vARB() functions +
Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044) +
Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh) +
Fixed broken "mgl" name mangling +
Indirect rending was broken for glMap* functions (bug 8899) +

+ + +

Internal code changes

+ +

The device driver functions ResizeBuffers and GetBufferSize have been +decprecated. +
OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit +more testing of the shading language functions. +

+ + +

To Do (someday) items

Switch to freeglut +
Increase MAX_DRAWBUFFERS +
Fix linux-glide target/driver. +
Improved lambda and derivative calculation for frag progs. +

+ + +
