You know I just realized, if there's ever a revised print edition it'll likely be sold as a second edition, and that'll make it the second edition of the second edition.
We’re changing the naming for this exact reason, the next iteration of the book is being called the “2018 edition” to match with the new edition scheme generally.
They just didn’t do the final upload; the text was finalized like six weeks ago. The idea was to do it at the same time the physical books shipped. If it’s not already fixed, should be done very soon. I’ve had the PDF in my inbox for a few weeks.
Hooray! I got to actually hold one last week, it was... wonderful. I am biased though :p
