I checked the PDF and this looks very interesting and comprehensive, any change you could give an eta for the final release and more specific the epub release?
Hi! I'm the author. I should remove that "pre-release" notice. Sure; there's plenty more that I could talk about, but there's also plenty of stuff there that you can use right now (and most of the stuff I wanted to talk about). Suggestions come in faster than I have time to implement them, so... Maybe this will never be done, and maybe that doesn't stop it from being a useful resource :-) I hope you enjoy it!
