Some drivers don't support all the features required in OpenGL 2.1. </p> <p> See the <a href="install.html">Compiling/Installing page</a> for prerequisites for DRI hardware acceleration. </p> <h2>MD5 checksums</h2> <pre> c89b63d253605ed40e8ac370d25a833c MesaLib-7.8.2.tar.gz 6be2d343a0089bfd395ce02aaf8adb57 MesaLib-7.8.2.tar.bz2 a04ad3b06ac5ff3969a003fa7bbf7d5b MesaLib-7.8.2.zip 7c213f92efeb471f0331670d5079d4c0 MesaDemos-7.8.2.tar.gz 757d9e2e06f48b1a52848be9b0307ced MesaDemos-7.8.2.tar.bz2 8d0e5cfe68b8ebf90265d350ae2c48b1 MesaDemos-7.8.2.zip b74482e3f44f35ed395c4aada4fd8240 MesaGLUT-7.8.2.tar.gz a471807b65e49c325808ba4551be93ed MesaGLUT-7.8.2.tar.bz2 9f190268c42be582ef66e47365ee61e3 MesaGLUT-7.8.2.zip </pre> <h2>New features</h2> <p>None.</p> <h2>Changes</h2> <ul> <li>Upgraded glext.h to version 61, and upgraded glxext.h </ul> <h2>Bug fixes</h2> <ul> <li>Fixed Gallium glDrawPixels(GL_DEPTH_COMPONENT). <li>Fixed Gallium Cell driver to buildable, runable state <li>Fixed bad error checking for glFramebufferRenderbuffer(attachment=GL_DEPTH_STENCIL_ATTACHMENT). <li>Fixed incorrect Z coordinate handling in "meta" glDraw/CopyPixels. <a href="https://bugs.freedesktop.org/show_bug.cgi?id=23670">Bug #23670</a>.</li> <li>Assorted i965 driver fixes.
