  17 <h1>Mesa 7.8.2 Release Notes / June 17, 2010</h1>
  18
  19 <p>
  20 Mesa 7.8.2 is a bug fix release which fixes bugs found since the 7.8.1 release.
  21 </p>
  22 <p>
  23 Mesa 7.8.2 implements the OpenGL 2.1 API, but the version reported by
  24 glGetString(GL_VERSION) depends on the particular driver being used.
  25 Some drivers don't support all the features required in OpenGL 2.1.
  26 </p>
  27 <p>
  28 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
  29 for DRI hardware acceleration.
