Notable Bug Fixes
- Fixed various sources of PHP 7.2 errors throughout the code base.
- Updated Unbound to 1.8.1 to address issues with memory leaks, especially in DNS over TLS support.
- Updated strongSwan to 5.7.1.
- Improved IPsec VTI compatibility with third-party vendor implementations.
filterdnsdaemon has been completely rewritten to address a number of issues.
- Fixed issues with package reinstallation after restoring a configuration backup.
- Fixed issues with Hyper-V
hn(4)network interfaces and IPv6 as well as issues with ALTQ.
Notable New Features
- Added GUI options to control
sshguardsensitivity and whitelisting to allow users to fine-tune the behavior of the brute force login protection.
- Added support for LDAP client certificates on authentication servers. (Factory only)
- Added schedule (cron) support to AutoConfigBackup.
Due to the significant nature of the changes in 2.4.4 and later, warnings and error messages, particularly from PHP and package updates, are likely to occur during the upgrade process. In nearly all cases these errors are a harmless side effect of the changes between FreeBSD 11.1 and 11.2 and between PHP 5.6 and PHP 7.2.
Always take a backup of the firewall configuration prior to any major change to the firewall, such as an upgrade.
Do not upgrade packages before upgrading pfSense! Either remove all packages or leave the packages alone before running the update.
The upgrade will take several minutes to complete. The exact time varies based on download speed, hardware speed, and other factors such installed packages. Be patient during the upgrade and allow the firewall enough time to complete the entire process. After the update packages finish downloading it could take 10-20 minutes or more until the upgrade process ends. The firewall may reboot several times during the upgrade process. Monitor the upgrade from the firewall console for the most accurate view.
Consult the Upgrade Guide for additional information about performing upgrades to pfSense software.
