From the folks over at pfSense
We are happy to announce the release of pfSense® software version 2.3!
The most significant changes in this release are a rewrite of the
webGUI utilizing Bootstrap, and the underlying system, including the
base system and kernel, being converted entirely to FreeBSD pkg. The
pkg conversion enables us to update pieces of the system individually
going forward, rather than the monolithic updates of the past. The
webGUI rewrite brings a new responsive look and feel to pfSense
requiring a minimum of resizing or scrolling on a wide range of
devices from desktop to mobile phones.
