Hi there,

For more than 8 years now, OPNsense is driving innovation through
modularising and hardening the open source firewall, with simple
and reliable firmware upgrades, multi-language support, 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.  <3

Migration notes, known issues and limitations:

o LibreSSL flavour has been discontinued.  Switch to OpenSSL flavour to proceed with the upgrade.
o StrongSwan IPsec configuration now uses the preferred swanctl.conf instead of the deprecated ipsec.conf which could lead to connectivity issues in ambiguous cases.  Subtle bugs cannot be ruled out as well so please raise an issue on GitHub to be able to investigate each case.
o The new IPsec connections pages and API create an idependent set of connections following the design of swanctl.conf.  Legacy tunnel settings cannot be managed from the API and are not migrated.
