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 97 GL_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 Superseded by the ARB versions. 98 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
