The developers of pfSense have made available version 2.3.5-RELEASE. As mentioned below, 2.3.5 is a security and stability focused release (KRACK issue, updated base system packages, WebGUI improvements, etc) while they will continue to work on version 2.4.X. You can download the ISO/image file here.

pfSense® software version 2.3.5 is now available for upgrades!

As we have promised, will will continue to deliver security and stability fixes to the pfSense 2.3.x line even after we have released pfSense 2.4.0, since i386 and NanoBSD were deprecated in pfSense 2.4.0. These updates will continue for a minimum of one year after the pfSense 2.4.0 release date, which means they will continue through at least October 2018.

Important Information

At this time, pfSense 2.3.x is a Security and Errata maintenance branch only. pfSense 2.4.x is the primary stable supported branch. If the firewall hardware is capable of running pfSense 2.4.x, consider upgrading to that release instead.

In case you missed the pfSense 2.4.0 release, see the 2.4.0 Release Notes and the previous 2.4.0 Release Highlights post.
