[HOpenGL] Open GL 3.2

Hello! (new to the list) I am taking a course in computer graphics, so i installed the latest version of the OpenGL package through cabal. At the top of of the documentation page it says OpenGL 3.2, but when i read different parts of the documentation on hoogle it says OpenGL 2.1 every here and there. What's what? (and if I can, how do i load my GLSL code?) hello! // Alexander, Gothenburg
