Mesa 17.1.0 Release Notes / May 10, 2017
========================================

Mesa 17.1.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for :ref:`Mesa 17.1.1 <calendar>`.

Mesa 17.1.0 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
-------

-  Removed the ilo gallium driver.
-  The configure option --enable-gallium-llvm is superseded by
   --enable-llvm.
-  The swr driver now requires LLVM >= 3.9.0 and a C++14 capable
   compiler.
-  The radeonsi driver now requires LLVM 3.8.0.
-  The MESA_GLSL=opt and MESA_GLSL=no_opt environment vars have been
   removed.
-  The --with-egl-platforms configure option is deprecated. Use
   --with-platforms instead.
