Hi Jonathan,
Thank you very much for pushing changes.
Below answers to your questions:
1. Is there a paperback for the new version of the book? I couldn't seem
to find it, but I may be looking in the wrong place.
You're right, the paperback version will be in print in a few weeks. I think we'll publish it, but if you think it is a mistake to be ahead of the schedule, let's remove the optimistic assumptions.
2. I don't know if we want to link directly to a PDF for the older
edition of the book. To date, we haven't directly linked to the PDFs for
other books. It would also indicate that to me that there isn't a
paperback version of that book, as the entry currently states.
As a proof that the previous version of the book was printed, I can refer to Bruce's post. Look at front and rear images links.
If you think that we should change something - let me know.
