17 <h1>Mesa
17.2.6 Release Notes / November
25,
2017</h1>
20 Mesa
17.2.6 is a bug fix release which fixes bugs found since the
17.2.5 release.
23 Mesa
17.2.6 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 because compatibility contexts are not supported.
