Status of OpenGL 3.x features in Mesa Note: when an item is marked as "DONE" it means all the core Mesa infrastructure is complete but it may be the case that few (if any) drivers implement the features. OpenGL Core and Compatibility context support OpenGL 3.1 and later versions are only supported with the Core profile. There are no plans to support GL_ARB_compatibility. The last supported OpenGL version with all deprecated features is 3.0. Some of the later GL features are exposed in the 3.0 context as extensions.
