New Release Candidate

OPNsense 19.1-RC1 released

Hi there,

For almost four 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.

We thank all of you for helping test, shape and contribute to the project! We know it would not be the same without you.

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