FreeBSD support
Delivered with the release your files expect
FreeBSD 11.4, 12.2, 13.0 and 14.0 are supported. One warning stated plainly: all four of those releases are outside the FreeBSD Project's supported list and no longer receive security updates (11.4 since September 2021, 12.2 since March 2022, 13.0 since August 2022, 14.0 since September 2024). If your files do not force the issue, pick a supported release; if they do, keep the server behind a firewall with only the ports you need open. If you know which release your file package was built against, note it on your order and the server arrives with it installed. Ubuntu and Debian images are ready if you compile on a separate Linux box.
