Miller) 78<li>Initial support for separate compilation units in GLSL compiler. 79<li>Increased max number of generic GLSL varying variables to 16 (formerly 8). 80<li>GLSL linker now detects when too many varying variables are used. 81<li>Optimize-out redundant glMaterial and glShadeModel calls in display lists 82<li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler. 83</ul> 84 85 86<h2>Bug fixes</h2> 87<ul> 88<li>Lots of i965 driver bug fixes 89<li>Fixed some GLSL preprocessor bugs 90<li>GLSL: continue inside of a for-loop didn't work 91</ul> 92 93 94<h2>Changes</h2> 95<ul> 96<li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and 97GL_SGIX_depth_texture extensions. Superseded by the ARB versions. 98<li>Omitted some old Mesa demos from the release tarballs, added some others. 99</ul> 100 101</body> 102</html> 103
