Mesa 17.4.0 Release Notes / March 27 2018

+ +

+Mesa 17.4.0 is a new development release. +People who are concerned with stability and reliability should stick +with a previous release or wait for Mesa 17.4.1. +

+Mesa 17.4.0 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. +

+ + +

SHA256 checksums

+TBD.
+

+ + +

New features

+ +

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

+ +

Disk shader cache support for i965 when MESA_GLSL_CACHE_DISABLE environment variable is set to "0" or "false"
GL_ARB_shader_atomic_counters and GL_ARB_shader_atomic_counter_ops on r600/evergreen+
GL_ARB_shader_image_load_store and GL_ARB_shader_image_size on r600/evergreen+
GL_ARB_shader_storage_buffer_object on r600/evergreen+
+
GL_ARB_compute_shader on r600/evergreen+
+
GL_ARB_cull_distance on r600/evergreen+
GL_ARB_enhanced_layouts on r600/evergreen+
GL_ARB_bindless_texture on nvc0/kepler
OpenGL 4.3 on r600/evergreen with hw fp64 support
Support 1 binary format for GL_ARB_get_program_binary on i965. + (For the 18.0 release, 0 formats continue to be supported in + compatibility profiles.)
Cannonlake support on i965 and anv
