1Mesa 7.9.2 Release Notes / March 2, 2011 2======================================== 3 4Mesa 7.9.2 is a bug fix release which fixes bugs found since the 7.9.1 5release. 6 7Mesa 7.9.2 implements the OpenGL 2.1 API, but the version reported by 8glGetString(GL_VERSION) depends on the particular driver being used. 9Some drivers don't support all the features required in OpenGL 2.1. 10 11See the :doc:`Compiling/Installing page <../install>` for 12prerequisites for DRI hardware acceleration. 13 14MD5 checksums 15------------- 16 17:: 18 19 eb4ab8c1a03386def3ea34b1358e9cda MesaLib-7.9.2.tar.gz
