Mesa 19.1.2 Release Notes / July 9, 2019
========================================

Mesa 19.1.2 is a bug fix release which fixes bugs found since the 19.1.1
release.

Mesa 19.1.2 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.
