OpenGL 4.1 Learning Resources

What are some good resources for learning about OpenGL 4.1 aimed at someone relatively new to graphical programming?

I know this was asked before, but I think that ~ 9 months will give us more.

I know that the OpenGL Programming Guide: The Official OpenGL Learning Guide, version 4.1 (8th edition) is apparently coming out in October, but is there anything else? It seems that some serious changes have occurred, and I would not want my time to study until this edition of the book was wasted. Sites can also work if they focus on 4.1.

Thank.
