Those that have them, Guidance Notes; how frequently are they actually updated (beside changing yellow to blue)?
I'm seriously considering getting some 17th edition GNs as they're a hell of a lot cheaper than the updated ones; if the actual content isn't changed then I just might but don't know what of anything in the GNs have changed.
Any ideas?
