Mesa 18.2.4 Release Notes / October 31, 2018 — The Mesa 3D Graphics Library latest documentation

# Mesa 18.2.4 Release Notes / October 31, 2018

Mesa 18.2.4 is a bug fix release which fixes bugs found since the 18.2.4 release.

Mesa 18.2.4 implements the OpenGL 4.5 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don’t support all the features required in OpenGL 4.5. OpenGL 4.5 is only available if requested at context creation. Compatibility contexts may report a lower version depending on each driver.
