   1 Mesa 19.2.1 Release Notes / 2019-10-09
   2 ======================================
   3
   4 Mesa 19.2.1 is a bug fix release which fixes bugs found since the 19.2.0
   5 release.
   6
   7 Mesa 19.2.1 implements the OpenGL 4.5 API, but the version reported by
   8 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
   9 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
  10 used. Some drivers don't support all the features required in OpenGL
  11 4.5. OpenGL 4.5 is **only** available if requested at context creation.
  12 Compatibility contexts may report a lower version depending on each
  13 driver.
  14
  15 Mesa 19.2.1 implements the Vulkan 1.1 API, but the version reported by
  16 the apiVersion property of the VkPhysicalDeviceProperties struct depends
  17 on the particular driver being used.
