# The Mesa 3D Graphics Library

# Mesa 17.3.0 Release Notes / TBD

Mesa 17.3.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 17.3.1.

Mesa 17.3.0 implements the OpenGL 4.5 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 4.5. OpenGL 4.5 is only available if requested at context creation because compatibility contexts are not supported.

## New features

- libtxc_dxtn is now integrated into Mesa. GL_EXT_texture_compression_s3tc and GL_ANGLE_texture_compression_dxt are now always enabled on drivers that support them
- GL_ARB_indirect_parameters on i965/gen7+
- GL_ARB_polygon_offset_clamp on i965, nv50, nvc0, r600, radeonsi, llvmpipe, swr
- GL_ARB_transform_feedback_overflow_query on radeonsi
- GL_ARB_texture_filter_anisotropic on i965, nv50, nvc0, r600, radeonsi
- GL_EXT_memory_object on radeonsi
- GL_EXT_memory_object_fd on radeonsi
