# Mesa 7.4.1 Release Notes / 18 April 2009

Mesa 7.4.1 is a stable development release fixing bugs since the 7.4 release.

Mesa 7.4.1 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 Compiling/Installing page for prerequisites for DRI hardware acceleration.

## Bug fixes

- Fixed a two-sided lighting bug in fixed-function-to-GPU code generation
- Fixed some Darwin issues (Jeremy Huddleston)
- Indexing the GLSL gl_EyePlane[] or gl_ObjectPlane[] arrays with a variable was broken, bug 20986
- Fixed incorrect texture unit bias in TXB instruction
- glTexParameter settings weren't always propogated to drivers
- Assorted vertex/fragment program bug fixes
- Fixed point rendering in software rasterizer
- Fixed potential deadlock in object hash functions
- Fix a couple bugs surrounding front-buffer rendering with DRI2, but this is not quite complete.
- Fixed glPopAttrib() bug when restoring user clip planes
