Mesa 19.1.4 is released. Install Mesa 3D Graphics Library for Linux Ubuntu Systems. The Mesa project began as an open-source implementation of the OpenGL specification – a system for rendering interactive 3D graphics.
A variety of device drivers allows the Mesa libraries to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs.
Mesa 19.1.4
Mesa 19.1.4 is a bug fix release which fixes bugs found since the 19.1.3 release. Mesa 19.1.4 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.
