The long wait is over. Fresh copies of The Book of PF, 4th Edition arrived here today.
Which means: I'll bring some to upcoming conferences! More on all this in the blog post https://nxdomain.no/~peter/its_real_its_here.html (or if you're fine with Google's trackers, https://bsdly.blogspot.com/2026/03/the-book-of-pf-4th-edition-its-here-its.html) Now please go to https://www.openbsd.org/donations.html too, once you've done the reading :) All the best, Peter -- Peter N.
