17<h1>Mesa 18.2.4 Release Notes / October 31, 2018</h1>
18
19<p>
20Mesa 18.2.4 is a bug fix release which fixes bugs found since the 18.2.4 release.
21</p>
22<p>
23Mesa 18.2.4 implements the OpenGL 4.5 API, but the version reported by
24glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
25glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
26Some drivers don't support all the features required in OpenGL 4.5.  OpenGL
274.5 is <strong>only</strong> available if requested at context creation.
28Compatibility contexts may report a lower version depending on each driver.
