A small story from the trenches: if you are like us at @startmail and prefer to run proven technology for critical components, you may be late with upgrading your #FreeBSD servers from release 13 to 14. At least we were.
Our routers/firewalls run FreeBSD and come in pairs. We use #pfsync to keep pf states in sync between them so we can reboot them at will without any effects for end users.

@startmail@mastodon.social However, we hit a small snag after upgrading the first one in a pair: the pfsync messages sent by 14.x are not readable by 13.x, which caused some traffic to be blocked inadvertently. Whoops. Luckily it only led to some outgoing deliveries being postponed.
