2.4.4 New Features and Changes

Significant Changes

OS Upgrade:Base Operating System upgraded to FreeBSD 11.2-RELEASE-p3. As a part of moving to FreeBSD 11.2, new hardware support is included for C3000-based hardware.
PHP 7.2:PHP upgraded to 7.2, which required numerous changes to syntax throughout the source code and packages.
Routed IPsec (VTI):
 Routed IPsec is now possible using using FreeBSD if_ipsec(4) Virtual Tunnel Interfaces (VTI). #8544 (See also: Routed IPsec (VTI))
IPsec Speed Improvements:
 The new Asynchronous Cryptography option under the IPsec Advanced Settings tab can dramatically improve IPsec performance on multi-core hardware #8772
Default Gateway Group:
 The default gateway may now be configured using a Gateway Group setup for failover (each gateway on a different tier), which replaces Default Gateway Switching. #8187
Limiter AQM/Queue Schedulers:
 Limiters now include support for several Active Queue Management (AQM) methods and Queue Scheduler configurations such as FQ_CODEL. #6620 (See also: pfSense PR #3941)
Certificate Subject Requirements:
 The Certificate Manager and OpenVPN wizard now only require the Common Name to be set, and all other fields are optional. #8381
AutoConfigBackup is free!:
 AutoConfigBackup now integrated and free for all to use. (See also: Using the AutoConfigBackup Service)
DNS over TLS:The DNS Resolver now includes support for DNS over TLS as both a client and a server, including for domain overrides. #8388 #8030 #8431
Captive Portal Authentication:
 Captive Portal authentication is now integrated with the User Manager system. Captive Portal instances may now use RADIUS, LDAP, or Local Authentication like other integrated services. The firewall will migrate existing Captive Portal RADIUS settings to the User Manager automatically on upgrade.
Captive Portal HTML Design and Usability:
 The default Captive Portal page has been redesigned. Controls have also been added which allow for the logo and background images and Terms of Service text to be customized without editing and uploading custom HTML code. #8793
Integrated Switch Improvements:
 Netgate devices with integrated switches such as the SG-3100 and XG-7100 can now configure per-port speed and duplex settings, discrete port configuration interfaces can now be tied to switch ports for up/down status, and LAGG support is also now available (Load Balance mode only)

Errata

Warning

Third party packages from alternate repositories are causing problems for users with the upgrade process and also with post-upgrade behavior. These packages have never been supported, and had to be manually added by users outside of the GUI.

Due to the major changes required for FreeBSD 11.2 and PHP 7.2, third party packages from alternate repositories cannot be present during the upgrade. There is no way to predict if a third party package supports the new version or will cause the upgrade itself to fail.

The upgrade process will automatically remove pfSense-pkg-* packages installed from alternate repositories. After the upgrade completes, the user can reinstall these packages. Packages from alternate repositories will not appear in the Installed Packages list in the GUI, and must be entirely managed in the command line.

This change does not affect packages installed from the official pfSense package repository.
