Version 2.4.4 of pfSense has been released. This package is based on the FreeBSD operating system and focuses on router and firewall tasks. It started in 2004 as a fork of m0n0wall due to differing views among the developers and over the years has grown into a router and firewall package that can be deployed in both small and very large environments. For more information, please refer to this page† The highlights for this release are as follows:

- PHP 7.2: PHP upgraded to version 7.2, which required numerous changes to syntax throughout the source code and packages.
- Routed IPsec (VTI): Routed IPsec is now possible using FreeBSD if_ipsec(4) Virtual Tunnel Interfaces (VTI).
- IPsec Speed Improvements: The new Asynchronous Cryptography option under the IPsec Advanced Settings tab can dramatically improve IPsec performance on multi-core hardware.
- Default Gateway Group: The default gateway may now be configured using a Gateway Group setup for failover, which replaces Default Gateway Switching.
- Limiter AQM/Queue Schedulers: Limiters now include support for several Active Queue Management (AQM) methods and Queue Scheduler configurations such as FQ_CODEL.
