  25 <h2>New features</h2>
  26 <ul>
  27 <li>New DRI memory manager system.  Currently used by the i915tex driver.
  28 Other DRI drivers will be updated to use the new memory manager in coming
  29 months.
  30 <br>
  31 To use the new driver you'll need the most recent DRM library and drivers
  32 (version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
  33 <br>
  34 New features resulting from this work include:
  35 <ul>
  36 <li>EXT_framebuffer_objects, render to texture
  37 <li>ARB_pixel_buffer_objects
  38 <li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
  39 <li>Accelerated texture uploads from pixel buffer objects
  40 <li>Potentially texturing directly from the pixel buffer object (zero
  41 copy texturing).
  42 </ul>
  43 <li>New Intel i965 DRI driver
  44 <li>New <code>minstall</code> script to replace normal install program
  45 <li>Faster fragment program execution in software
  46 <li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
  47     GLX_SGI_make_current_read</a> to the following drivers:</li>
  48     <ul>
  49     <li>radeon</li>
  50     <li>savage</li>
  51     <li>mga</li>
  52     </ul>
  53 </ul>

  55 <h2>Bug fixes</h2>
  56 <ul>
  57 <li>fixed invalid memory read while rendering textured points (bug 8320)
  58 <li>fixed problems with freebsd-dri configuration (bug 8344)
  59 <li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
  60 <li>OPTION NV_position_invariant didn't work in NV vertex programs
  61 <li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
  62 <li>Line clipping was broken in some circumstances
  63 <li>fragment.fogcoord register didn't always contain the correct value
  64 <li>RGBA logicops didn't work reliably in some DRI drivers
  65 <li>Fixed broken RGBA LogicOps in Intel DRI drivers
  66 <li>Fixed some fragment program bugs in Intel i915 DRI driver
  67 <li>Fixed glGetVertexAttribfvARB bug 8883
  68 <li>Implemented glGetUniform[fi]vARB() functions
  69 <li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
  70 <li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
  71 <li>Fixed broken "mgl" name mangling
  72 </ul>

  75 <h2>Internal code changes</h2>
  76
  77 <ul>
  78 <li>The device driver functions ResizeBuffers and GetBufferSize have been
  79 decprecated.
  80 <li>OpenGL 2.0 and 2.1 support is nearly done.  We need to do quite a bit
  81 more testing of the shading language functions.
  82 </ul>
  83
  84
  85 <h2>To Do (someday) items</h2>
  86 <ul>
  87 <li>Switch to freeglut
  88 <li>Increase MAX_DRAWBUFFERS
  89 <li>Fix linux-glide target/driver.
  90 <li>Improved lambda and derivative calculation for frag progs.
  91 </ul>
