  17 <h1>Mesa 19.2.1 Release Notes / 2019-10-09</h1>
  18
  19 <p>
  20     Mesa 19.2.1 is a bug fix release which fixes bugs found since the 19.2.0 release.
  21 </p>
  22 <p>
  23 Mesa 19.2.1 implements the OpenGL 4.5 API, but the version reported by
  24 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  25 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
  26 Some drivers don't support all the features required in OpenGL 4.5. OpenGL
  27 4.5 is <strong>only</strong> available if requested at context creation.
  28 Compatibility contexts may report a lower version depending on each driver.
  29 </p>
  30 <p>
  31 Mesa 19.2.1 implements the Vulkan 1.1 API, but the version reported by
  32 the apiVersion property of the VkPhysicalDeviceProperties struct
  33 depends on the particular driver being used.
