We are still working on The Book of PF, 4th ed.

Preorders are open at https://nostarch.com/book-of-pf-4th-edition, read about the work at https://nxdomain.no/~peter/yes_the_book_of_pf_4th_ed_is_coming.html (also tracked at https://bsdly.blogspot.com/2025/07/yes-book-of-pf-4th-edition-is-coming.html) #bookofpf #newedition #freebsdd #openbsd #pf #packetfilter #networking #security #freesoftware #libresoftware

Today, early access reader feedback for The Book of PF, 4th edition proved to me that early access is worth doing.
