Friends, Long rumored and eagerly anticipated by some, the fourth edition of The Book of PF is now available for preorder from the publisher's site at https://nostarch.com/book-of-pf-4th-edition
The text is in the final editing phases, and we are hoping to have physical copies available by the time of EuroBSDcon 2025. The fourth edition was written to bring the text into sync with the realities of the modern Internet, seen from the perspective of someone working with OpenBSD 7.8 or FreeBSD 14-RELEASE. The structure and chapter titles will be recognizable to readers of the previous edition, with the content updated to reflect the realities of the modern Internet. When the actual physical copies become ready, I will make an effort to make the actual publication date a fun one (suggestions appreciated) All the best, Peter -- Peter N. M.
