Hi there,

For over 5 years now, OPNsense is driving innovation through modularising
and hardening the open source firewall, with simple and reliable firmware
upgrades, multi-language support, HardenedBSD security, fast adoption of
upstream software updates as well as clear and stable 2-Clause BSD licensing.

20.1, nicknamed "Keen Kingfisher", is a subtle improvement on sustainable
firewall experience.  This release adds VXLAN and additional loopback device
support, IPsec public key authentication and elliptic curve TLS certificate
creation amongst others.  Third party software has been updated to their
latest versions.  The logging frontend was rewritten for MVC with seamless
API support.  On the far side the documentation increased in quality as well
as quantity and now presents itself in a familiar menu layout.

Download links, an installation guide[1] and the checksums for the images
can be found below as well.
