  32 <h2>New features</h2>
  33 <ul>
  34 <li>New DRI memory manager system.  Currently used by the i915tex driver.
  35 Other DRI drivers will be updated to use the new memory manager in coming
  36 months.
  37 <br>
  38 To use the new driver you'll need the most recent DRM library and drivers
  39 (version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
  40 <br>
  41 New features resulting from this work include:
  42 <ul>
  43 <li>EXT_framebuffer_objects, render to texture
  44 <li>ARB_pixel_buffer_objects
  45 <li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
  46 <li>Accelerated texture uploads from pixel buffer objects
  47 <li>Potentially texturing directly from the pixel buffer object (zero
  48 copy texturing).
  49 </ul>
  50 <li>New Intel i965 DRI driver
  51 <li>New <code>minstall</code> script to replace normal install program
  52 <li>Faster fragment program execution in software
  53 <li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
  54     GLX_SGI_make_current_read</a> to the following drivers:
  55     <ul>
  56     <li>radeon</li>
  57     <li>savage</li>
  58     <li>mga</li>
  59     <li>tdfx</li>
  60     </ul>
  61 <li>Added support for ARB_occlusion_query to the tdfx driver (Ian
  62 Romanick).</li>
  63 </ul>
  64
  65 <h2>Bug fixes</h2>
  66 <ul>
  67 <li>fixed invalid memory read while rendering textured points (bug 8320)
  68 <li>fixed problems with freebsd-dri configuration (bug 8344)
  69 <li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
  70 <li>OPTION NV_position_invariant didn't work in NV vertex programs
  71 <li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
  72 <li>Line clipping was broken in some circumstances
  73 <li>fragment.fogcoord register didn't always contain the correct value
  74 <li>RGBA logicops didn't work reliably in some DRI drivers
  75 <li>Fixed broken RGBA LogicOps in Intel DRI drivers
  76 <li>Fixed some fragment program bugs in Intel i915 DRI driver
  77 <li>Fixed glGetVertexAttribfvARB bug 8883
  78 <li>Implemented glGetUniform[fi]vARB() functions
  79 <li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
  80 <li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
  81 <li>Fixed broken "mgl" name mangling
  82 <li>Indirect rending was broken for glMap* functions (bug 8899)
  83 </ul>
  84
  85
  86 <h2>Internal code changes</h2>
  87
  88 <ul>
  89 <li>The device driver functions ResizeBuffers and GetBufferSize have been
  90 decprecated.
  91 <li>OpenGL 2.0 and 2.1 support is nearly done.  We need to do quite a bit
  92 more testing of the shading language functions.
  93 </ul>
  94
  95
  96 <h2>To Do (someday) items</h2>
  97 <ul>
  98 <li>Switch to freeglut
  99 <li>Increase MAX_DRAWBUFFERS
 100 <li>Fix linux-glide target/driver.
 101 <li>Improved lambda and derivative calculation for frag progs.
 102 </ul>
