  18 <h1>Mesa 20.0.5 Release Notes / 2020-04-22</h1>
  19
  20 <p>
  21     Mesa 20.0.5 is a bug fix release which fixes bugs found since the 20.0.4 release.
  22 </p>
  23 <p>
  24 Mesa 20.0.5 implements the OpenGL 4.6 API, but the version reported by
  25 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  26 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
  27 Some drivers don't support all the features required in OpenGL 4.6. OpenGL
  28 4.6 is <strong>only</strong> available if requested at context creation.
  29 Compatibility contexts may report a lower version depending on each driver.
  30 </p>
  31 <p>
  32 Mesa 20.0.5 implements the Vulkan 1.2 API, but the version reported by
  33 the apiVersion property of the VkPhysicalDeviceProperties struct
  34 depends on the particular driver being used.
  35 </p>
