  32 <h2>New Features</h2>
  33 <ul>
  34 <li>OpenGL Shading language support
  35 <br>
  36    This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
  37    GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions.  Most of
  38    the work was done by Michal Krol.
  39    There's probably a fair number of bugs since this is a pretty large,
  40    complicated body of code.
  41 <br>
  42    The OpenGL 2.0 interface to these features will be implemented in a
  43    future version of Mesa,
  44
  45 <li>GL_EXT_timer_query
  46 <br>
  47    Used to measure the time of OpenGL operations at high precision.
  48    Only supported in the software/Xlib driver at this time.
  49
  50 <li>GL_EXT_packed_depth_stencil
  51 <br>
  52    Defines a new GL_DEPTH_STENCIL_EXT pixel format.
  53
  54 <li>GL_EXT_framebuffer_blit
  55 <br>
  56    A simplified glCopyPixels-like feature for copying pixel rectangles.
  57
  58 <li>GL_ARB_half_float_pixel
  59 <br>
  60    Adds a new half-precision floating point format for image transfers,
  61    such as for glDrawPixels, glReadPixels, glTexImage, etc.
  62 </ul>
  63
  64 <h2>Changes</h2>
  65 <ul>
  66 <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
  67 <li>removed GL_SGIX/SGIS_pixel_texture extensions
  68 </ul>
  69 <h2>Bug fixes</h2>
  70 <ul>
  71 <li>fixed glxcontextmodes.c datatype problem (bug 5835)
  72 <li>fixed aix-gcc build/install bugs (bug 5874)
  73 <li>fixed some bugs in texture env program generation
  74 <li>glXCopyContext() didn't handle texture object bindings properly
  75 <li>glXCopyContext() didn't copy all lighting state
  76 <li>fixed FreeBSD config (Pedro Giffuni)
  77 <li>fixed some minor framebuffer object bugs
  78 <li>replaced dprintf() with _glu_printf() in GLU (bug 6244)
  79 <li>fixed a number of thread safety bugs/regressions
  80 <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339)
  81 <li>paletted texturing was broken w/ floating point palettes (K. Schultz)
  82 <li>lots of assorted framebuffer object bug fixes
  83 </ul>
  84
  85
  86 <h2>Known Issues</h2>
  87 <ul>
  88 <li>Rendering to depth textures will not work.  Rendering to GL_DEPTH_STENCIL
  89 textures should work.
  90 </ul>
  91
  92
  93 <h2>Driver Interface Changes</h2>
  94 <ul>
  95 <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
  96 the two-sided versions: Driver.Stencil*Separate().
  97 <li>Render-to-texture: The functions for rendering to textures have changed.
  98 </ul>
  99
 100
 101 <h2>To Do (someday) items</h2>
 102 <ul>
 103 <li>Switch to freeglut
 104 <li>Increase MAX_DRAWBUFFERS
 105 <li>Fix linux-glide target/driver.
 106 <li>Fix lambda calculation for frag progs.
 107 </ul>
