I would like to ensure, that all my openGL files are up to date. But I am a bit confused about how all the details about OpenGL's extensions work, i.e. what extensions are supported from where. I am using MS Visual C++ 6.0 for coding my OpenGL applications. But if I understand it correctly, the gl.h, glu.h and glaux.h files provided by MS only supports OpenGL ver. 1.1. Is that correct or must I download some updated versions from MS? Besides that, I have downloaded glext.h, wglext.h and glxext.h from opengl.org. I have also downloaded the latest drivers for my graphics platform. Is there anymore to do to ensure, that my OpenGL version is up to date?
