Subject: [PATCH] Third edition: relicense to CC-BY-SA 4.0 International

My contract with O'Reilly said:

The U.S. hard copy edition was released 2023-12-12, which is now over 12
months in the past, so I'm exercising my right.

 ## Where is the PDF?
 
 **The current edition is not available as a PDF, deliberately**. Why? Because the publisher (O'Reilly Media) is a for-profit publisher who puts considerable resources behind producing, editing and distributing this book. The third edition of "Mastering Bitcoin" is available under a CC-BY-NC-ND license, not a CC-BY-SA license. The book will eventually (within a year of publication) be released under a CC-BY-SA license, at which point PDF copies and translations will be allowed (a PDF is a "derivative" product, which is what the "ND-NoDerivatives" part of the license prohibits).

 Making PDF copies violates the license and interferes with the publisher's and the authors' ability to earn from their work. Furthermore, if you make it so the publisher can't recoup their investment, they may delay the release into CC-BY-SA. A beautifully rendered PDF or epub version of this book is offered for sale by the publisher. Convenient packaging is the for-profit product, whereas the version available here is slightly less convenient but entirely free for personal and non-commercial use. If you want convenience and nice packaging, buy the book!
 
 Please don't create or distribute PDFs until the license is changed to CC-BY-SA. It is rare for a publisher to even agree to a CC-BY-NC-ND license. Don't make it harder for free culture by violating even that, already generous, license.
