3rd edition and all subsequent editions as long as you're subscribed! Get the drafts right now and complete book after at least 8 months of consecutive active subscription, when 2.0 is ready, if your subscription is still active at that moment (if you cancel subscription, you only get the drafts up to that point). Does NOT include access to the 1st and 2nd editions! To read v2.0 right now, please select tier 2.0, download the book, and then switch to this tier for 3.0. Your name will be included in acknowledgments at the end of the book (opt-out).

Download the book PDF and Leiningen code of v1.0 and v2.0 (draft) immediately. Receive the final version of v2.0 when I complete it. Delete pledge or move to a lower v3.0 subscription tier after download; unless you wish to generously support me every month.
