The developers of pfSense have made available 2.4.1-RELEASE, just a few weeks shy of 2.4.0. This version includes security patches and various stability fixes, including WPA2 Key Reinstallation Attack issues, VT console race condition panic, bsnmpd, and more. See the full list of changes at the link below. You can download the ISO/image files here.

We are excited to announce the release of pfSense® software version 2.4.1, now available for new installations and upgrades!

pfSense software version 2.4.1 is a maintenance release bringing security patches and stability fixes for issues discovered in pfSense 2.4.0-RELEASE.

pfSense 2.4.1-RELEASE updates and installation images are available now!

Security advisories from upstream projects announced after pfSense 2.4.0-RELEASE made this additional release necessary, soon after 2.4.0, to keep firewalls safe and secure. We used this opportunity to also include some platform fixes for new hardware we are offering and to deliver important stability fixes for issues that some users encountered with pfSense 2.4.0-RELEASE. Even with the rapid turnaround, we feel the set of changes merits a version number bump rather than a patch release.
