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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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