  22 New 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
  57 Bug 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
  78 Internal 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
  86 To 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.
