< H1 > Mesa 7.9.2 Release Notes / TBD< / H1 >
2011-10-23 07:29:21 -06:00
< p >
Mesa 7.9.2 is a bug fix release which fixes bugs found since the 7.9.1 release.
< / p >
< p >
Mesa 7.9.2 implements the OpenGL 2.1 API, but the version reported by
glGetString(GL_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 2.1.

See the < a href = "install.html" > Compiling/Installing page< / a > for prerequisites
for DRI hardware acceleration.
