pfSense 2.4.1 已发布，pfSense 是一个 FreeBSD 下的免费开源的防火墙和路由器软件。它使用的技术包括
Packet Filter，FreeBSD 6.x（或 DragonFly BSD，假如 ALTQ 和 CARP 完成了的话）的
ALTQ（以出色地支持分组队列），集成的包管理系统（以为其环境扩展新的特性）。
更新内容：
Fixes for the set of WPA2 Key Reinstallation Attack issues commonly known as KRACK Fixed a VT console race condition panic at boot on VMware platforms (especially ESXi 6.5.0U1) #7925 Fixed
a bsnmpd problem that causes it to use excess CPU and RAM with the
hostres module in cases where drives support removable media but have no
media inserted #6882 Fixed
an upgrade problem due to FreeBSD 11 removing legacy ada aliases, which
caused some older installs to fail when mounting root post-upgrade #7937 Changed the boot-time fsck process the ensure the disk is mounted read-only before running fsck in preen mode Changed
the VLAN interface names to use the ‘dotted’ format now utilized by
FreeBSD, which is shorter and helps to keep the interface name smaller
than the limit (16) This fixes the 4 digit VLAN issues when the NIC name
is 6 bytes long. This change was made not only to fix the name length
issue, but also to reduce the differences between how FreeBSD uses VLANs
and how they are used by pfSense interface functions. Fixed setting VLAN Priority in VLAN interface configuration #7748
