Mesa 18.1.0 Release Notes / May 18 2018
=======================================

Mesa 18.1.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 18.1.1.

Mesa 18.1.0 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.
Compatibility contexts may report a lower version depending on each
driver.

New features
------------

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

-  OpenGL 3.1 with ARB_compatibility on nv50, nvc0, r600, radeonsi,
   softpipe, llvmpipe, svga
-  GL_ARB_bindless_texture on nvc0/maxwell+
-  GL_ARB_transform_feedback_overflow_query on nvc0
-  GL_EXT_semaphore on radeonsi
-  GL_EXT_semaphore_fd on radeonsi
-  GL_EXT_shader_framebuffer_fetch on i965 on desktop GL (GLES was
   already supported)
-  GL_EXT_shader_framebuffer_fetch_non_coherent on i965
-  GL_KHR_blend_equation_advanced on radeonsi
-  Disk shader cache support for i965 enabled by default
