Paragraph "Development" (page 14 in the current version) answers your question: "The entire Crypto 101 project is publicly developed on GitHub under the crypto101 organization, including this book: https://github.com/crypto101/book " [...] "The copy of this book that you are reading right now is based on the git commit with hash 3f89ec3 , also known as 0.4.0-22-g3f89ec3" Then, looking at the commits, yes the book changed a lot since 2014: https://github.com/crypto101/book/commits/master

Thanks for the suggestions! I think that being able to build on standard free texlive installations would be a wonderful feature, but this the first time I've heard of the microtype package. Are you saying I can just turn it on and it'd be better? I've skimmed the CTAN entry and it suggests that it'd work with most fonts; does that include the ones I'm using now? (If so, does that mean that "use free fonts" and "use microtype" are two different tickets?) Thank you very much in advance. I've created two tickets for this: https://github.com/crypto101/book/issues/60 and https://github.com/crypto101/book/issues/61.

The book looks great. I don't have any experience in crypto really but will certainly be taking a look at the early chapters here for a foundation. edit: ignore the below, just got to this explanation in the book! > The entire Crypto 101 project is publicly developed on Github under the crypto101 organization, including this book. https://github.com/crypto101/book ---- Excuse me if this info's on the website (I can't get to it right now, HN "hug of death" it appears), will you be open sourcing contribution to the book? I'm not saying it's necessary or that I even recommend it, just curious about your authorship model (and noticed the CC license at the beginning). Also, did you make the book in LaTeX (or some TeX variant)? If so, will you be sharing the source? I always love looking at other people's TeX documents.
