The book is now available on Amazon, if you’re interested in purchasing a copy for yourself.
I am also organizing another student writing marathon for April to update the book. I’ll post more details as I have them.
Let me know if you’re interested in helping out!
The previous PDF that I posted had “Kickstarter Backer Edition” on the title page – I’ve removed that and added the “public” release which will appear in the “retail” version of the book, to which I will publish a link soon.
I have also made the LaTeX source code available in a GitHub repository. Feel free to add issues, fork a translation (as some previous commenters offered), or add new material!
Also, the hard copies came in today. Now I need to get my exam-preparing students to sit down with me and get get them addressed and in the mail!
