Will there be newer versions of the red and blue book? They seem to be at opengl1.4 while opengl now is at opengl3.0.
The red book has been at OpenGL 2.0 for some time. The blue book is still at 1.4. Newer varsions will probably appear some day, but it can take time.
The red book even reaches OpenGL 2.1 but the blue book seams deprecated, especially because now we have “the reference pages”
Still OpenGL 2.1 …
