# Mesa 11.0.4 Release Notes / October 24, 2015

Mesa 11.0.4 is a bug fix release which fixes bugs found since the 11.0.3 release.

Mesa 11.0.4 implements the OpenGL 4.1 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 4.1. OpenGL 4.1 is only available if requested at context creation because compatibility contexts are not supported.
