   1 Mesa 20.1.5 Release Notes / 2020-08-05
   2 ======================================
   3
   4 Mesa 20.1.5 is a bug fix release which fixes bugs found since the 20.1.4 release.
   5
   6 Mesa 20.1.5 implements the OpenGL 4.6 API, but the version reported by
   7 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
   8 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
   9 Some drivers don't support all the features required in OpenGL 4.6. OpenGL
  10 4.6 is **only** available if requested at context creation.
  11 Compatibility contexts may report a lower version depending on each driver.
  12
  13 Mesa 20.1.5 implements the Vulkan 1.2 API, but the version reported by
  14 the apiVersion property of the VkPhysicalDeviceProperties struct
  15 depends on the particular driver being used.
