Mesa 18.2.0 Release Notes / September 7, 2018
=============================================

Mesa 18.2.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 18.2.1.

Mesa 18.2.0 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.
Compatibility contexts may report a lower version depending on each
driver.

libwayland-egl is now distributed by Wayland (since 1.15, `see
announcement <https://lists.freedesktop.org/archives/wayland-devel/2018-April/037767.html>`__),
and has been removed from Mesa in this release. Make sure you're using
an up-to-date version of Wayland to keep the functionality.

Changes
-------

-  Removed GL_EXT_polygon_offset applications should use glPolygonOffset
   instead.
-  Removed libwayland-egl, now part of Wayland
