Dear friends and followers,

For 3 and a half 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.

Another 6 months passed by ever so quickly! The main goal for 18.7, nicknamed “Happy Hippo”, is stability so we have not yet begun to adopt FreeBSD 11.2, but there are several of its Intel NIC driver updates included to bridge the gap until 19.1 comes out. The upgrade also includes a tremendous amount of IPv6 improvements including 6RD support as well as authentication and backup framework consolidation. Please also take note that QinQ is no longer included in this release.
