19.1.2 Release Notes / July
9,
2019</h1>
20 Mesa
19.1.2 is a bug fix release which fixes bugs found since the
19.1.1 release.
23 Mesa
19.1.2 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.
