22New features
23------------
24
25-  New DRI memory manager system. Currently used by the i915tex driver.
26   Other DRI drivers will be updated to use the new memory manager in
27   coming months.
28
29   To use the new driver you'll need the most recent DRM library and
30   drivers (version 2.2 or later) and a recent xf86-video-intel driver
31   module from X.org.
32
33   New features resulting from this work include:
34
35   -  EXT_framebuffer_objects, render to texture
36   -  ARB_pixel_buffer_objects
37   -  Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
38   -  Accelerated texture uploads from pixel buffer objects
39   -  Potentially texturing directly from the pixel buffer object (zero
40      copy texturing).
41
42-  New Intel i965 DRI driver
43-  New ``minstall`` script to replace normal install program
44-  Faster fragment program execution in software
45-  Added (or fixed) support for
46   `GLX_SGI_make_current_read <https://www.khronos.org/registry/OpenGL/extensions/SGI/GLX_SGI_make_current_read.txt>`__
47   to the following drivers:
48
49   -  radeon
50   -  savage
51   -  mga
52   -  tdfx
53
54-  Added support for ARB_occlusion_query to the tdfx driver (Ian
55   Romanick).
56
57Bug fixes
58---------
59
60-  fixed invalid memory read while rendering textured points (bug 8320)
61-  fixed problems with freebsd-dri configuration (bug 8344)
62-  Mesa's fake glxGetCurrentContext() wasn't thread-aware
63-  OPTION NV_position_invariant didn't work in NV vertex programs
64-  glDrawPixels into a user-created framebuffer object could crash Xlib
65   driver
66-  Line clipping was broken in some circumstances
67-  fragment.fogcoord register didn't always contain the correct value
68-  RGBA logicops didn't work reliably in some DRI drivers
69-  Fixed broken RGBA LogicOps in Intel DRI drivers
70-  Fixed some fragment program bugs in Intel i915 DRI driver
71-  Fixed glGetVertexAttribfvARB bug 8883
72-  Implemented glGetUniform[fi]vARB() functions
73-  Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
74-  Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
75-  Fixed broken "mgl" name mangling
76-  Indirect rending was broken for glMap\* functions (bug 8899)
77
78Internal code changes
79---------------------
80
81-  The device driver functions ResizeBuffers and GetBufferSize have been
82   decprecated.
83-  OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit
84   more testing of the shading language functions.
85
86To Do (someday) items
87---------------------
88
89-  Switch to freeglut
90-  Increase MAX_DRAWBUFFERS
91-  Fix linux-glide target/driver.
92-  Improved lambda and derivative calculation for frag progs.
