  24 <h2>New features</h2>
  25 <ul>
  26 <li>OpenGL 2.0 support.
  27 <li>Entirely new Shading Language code generator.
  28 <li>Much faster software execution of vertex, fragment shaders.
  29 <li>New vertex buffer object infrastructure (replaces old array_cache code).
  30 <li>Updated glext.h file (version 39)
  31 <li>Updated glxext.h file (version 18)
  32 <li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
  33     "multiple render targets" are really supported.
  34 </ul>
  35
  36 <h2>Bug fixes</h2>
  37 <ul>
  38 <li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
  39 <li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
  40 <li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
  41 <li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
  42 <li>1D convolution state could effect 2D image transfers
  43 </ul>

  46 <h2>Internal code changes</h2>
  47
  48 <ul>
  49 <li>Massive changes to the Shading Language compiler.
  50 <li>The _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and
  51 _TnlProgram fields have been moved.
  52 <li>The ctx->FragmentProgram._Active field has been removed.
  53 <li>The ctx->Vertex/FragmentProgram._Current fields point to the program
  54 in effect, whether it comes from a shader, user-program or generated
  55 fixed-function program.
  56 <li>The _UseTexEnvProgram field has been removed.
  57 </ul>
  58

  60 <h2>To Do (someday) items</h2>
  61 <ul>
  62 <li>Switch to freeglut
  63 <li>Fix linux-glide target/driver.
  64 <li>Improved lambda and derivative calculation for frag progs.
  65 </ul>
