Mesa 17.0.0 Release Notes / February 13, 2017
=============================================

Mesa 17.0.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 17.0.1.

Mesa 17.0.0 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.

Changes
-------

-  Building RADV requires --enable-gallium-llvm
-  The vulkan headers vk_platform.h and vulkan.h are no longer installed
-  The configure options --with-sha1 and --disable-shader-cache are
   removed alongside their respective library requirements
