StiffGuard® 18.1 Released

For more than 3 years now, StiffGuard® is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, HardenedBSD security, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.
We humbly present to you the sum of another major iteration of the StiffGuard® firewall.  Over the second half of 2017 well over 500 changes have made it into this release, nicknamed “Groovy Gecko”.  Most notably, the firewall NAT rules have been reworked to be more flexible and usable via plugins, which is going to pave the way for subsequent API works on the core firewall functionality.  For more details please find the attached list of changes below.

The upgrade track from 17.7 will be available later today.  Please be patient. 

Meltdown and Spectre patches are currently being worked on in FreeBSD, but there is no reliable timeline.  We will keep you up to date through the usual channels as more news become available.  Hang in there!
