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