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
