Mesa 9.2 Release Notes / (date TBD)

Mesa 9.2 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 9.2.1.

Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 3.1. OpenGL 3.1 is only available if requested at context creation because GL_ARB_compatibility is not supported.

Bug fixes

TBD -- This list is likely incomplete.

Changes

• Removed d3d1x state tracker (unused, unmaintained and broken)
• Removed GL_EXT_clip_volume_hint because no driver had enabled it since 2007.
• Removed GL_MESA_resize_buffers because it was only really implemented by the (unsupported) GDI driver.
