   1 Mesa 19.2.0 Release Notes / 2019.09.25
   2 ======================================
   3
   4 Mesa 19.2.0 is a new development release. People who are concerned with
   5 stability and reliability should stick with a previous release or wait
   6 for Mesa 19.2.1.
   7
   8 Mesa 19.2.0 implements the OpenGL 4.5 API, but the version reported by
   9 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  10 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
  11 used. Some drivers don't support all the features required in OpenGL
  12 4.5. OpenGL 4.5 is **only** available if requested at context creation.
  13 Compatibility contexts may report a lower version depending on each
  14 driver.
  15
  16 Mesa 19.2.0 implements the Vulkan 1.1 API, but the version reported by
  17 the apiVersion property of the VkPhysicalDeviceProperties struct depends
  18 on the particular driver being used.
