Mesa 17.3.0 Release Notes / December 8. 2017
============================================

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
------------

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

-  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
-  EGL_ANDROID_native_fence_sync on radeonsi with a future kernel
   (possibly 4.15)
-  EGL_IMG_context_priority on i965
