Mesa 7.10.1 is a bug fix release which fixes bugs found since the 7.10 release. 14 </p> 15 <p> 16 Mesa 7.10.1 implements the OpenGL 2.1 API, but the version reported by 17 glGetString(GL_VERSION) depends on the particular driver being used. 18 Some drivers don't support all the features required in OpenGL 2.1. 19 </p> 20 <p> 21 See the <a href="install.html">Compiling/Installing page</a> for prerequisites 22 for DRI hardware acceleration. 23 </p> 24 25 26 <h2>MD5 checksums</h2> 27 <pre> 28 4b4cee19f3bf16eb78bd4cc278ccf812 MesaLib-7.10.1.tar.gz 29 efe8da4d80c2a5d32a800770b8ce5dfa
