Is this directly from the authors? If yes, I'm a bit shocked given the prices for the book when searching for ed 1, ed 2 and ed 3 on Google. Please add a donation button to the site.
I just finished the first four sections and I love it. Thanks a lot!
They always do this when the next version of the book is close to coming out. The first 2 have been available for free for a while. It is expected with this that the 4th is coming soon.
