# The Mesa 3D Graphics Library

# Mesa 10.1 Release Notes / TBD

Mesa 10.1 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 10.1.1.

Mesa 10.1 implements the OpenGL 3.3 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 3.3. OpenGL 3.3 is only available if requested at context creation because compatibility contexts are not supported.

## New features

Note: some of the new features are only available with certain drivers.

- GL_ARB_draw_indirect on i965.
- GL_ARB_clear_buffer_object
- GL_ARB_viewport_array on i965.
- GL_ARB_map_buffer_alignment on all drivers that did not previously support it.
- GL_AMD_shader_trinary_minmax.
- GL_EXT_framebuffer_blit on r200 and radeon.
- Reduced memory usage for display lists.
- OpenGL 3.3 support on nv50, nvc0, r600 and radeonsi

## Bug fixes

TBD.

## Changes

- Removed support for the GL_MESA_texture_array extension. This extension enabled the use of texture array with fixed-function and assembly fragment shaders. No applications are known to use this extension.
