Quick question, I had apparently Pinboarded this in March 2014. I see the PDF is still pre-release. Has anything changed with this, or is it kinda just coming up again because of recent political climate.

I'm fine either way, just curious if this has changed drastically from what I had looked at previously.

"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
