# Mesa 19.1.5 Release Notes / August 23, 2019

Mesa 19.1.5 is a bug fix release which fixes bugs found since the 19.1.4 release.

Mesa 19.1.5 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.
