+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 <https://registry.khronos.org/OpenGL/extensions/SGI/GLX_SGI_make_current_read.txt>`__
+   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.
+
