Henning Brauer (henning@) has just sent an e-mail to misc@ announcing the publication of his presentation from BSDCan 2011. Weighing in at 82 pages, he gives a detailed overview of what happened to our favourite firewall in the last 10 years. I can still remember running IPF so a big thank you to all the developers involved in PF over the years is more than warranted.
Henning also reminds everybody that EuroBSDCon 2011 will be held in October in The Netherlands, with several OpenBSD developers presenting there. If you are in the area, make sure you stop by.
