Hi Ruud,
I notice that the solving guide was updated on 1 Sep. Is there any clean way to highlight what changed from the previous version?
I hate to print out a copy if nothing significant changed, but if a change in the techniques or examples is made, I will want to update where I have made notes on the copy I have already printed printed out.
It may not be worth it, but I thought I would bring it up.
Regards,
George
