OpenTK 0.3.9 comes with several enhancements to the opengl API, for example:
* separate namespaces for each extension category, i.e. GL.ARB.Foo or GL.EXT.Bar)
* overloads for opengl functions like: GL.Vertex3[fdis]v (they are all called GL.Vertex3 now)
* Better naming scheme for opengl enums (GL.Enums and GL.Enums.All).
Other noteworthy additions, include GameWindow support for keyboard input on Windows and Linux (GLControl pending), and many crash-bug fixes.
This release has been tested on 32- and 64bit Linux and Windows. OSX may work, too, (with X server), but is not yet supported.
