17 <h1>Mesa
18.2.1 Release Notes / September
21,
2018</h1>
20 Mesa
18.2.1 is a bug fix release which fixes bugs found since the
18.2.0 release.
23 Mesa
18.2.0 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.
