Unity 5 - GL Methods Gone

I’m using Unity 5 beta 17 (the latest from Unity3d.com), and my old scripts are no longer working. Currently I am trying to use GL.SetRevertBackFacing(), and MonoDevelop cannot find it (it’s not just hidden, like the ‘camera’ variable). Does anybody know where this has gone?

Thanks.

Never mind! It has been changed from the method GL.SetRevertBackfacing(bool) to the variable GL.invertCulling.
