| 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.
 | ||
| 
 | ||
| SHA256 checksums

| 
 | ||
| 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
