Dear all,

This update brings the usual mix of reliability fixes, plugin and third party software updates: FreeBSD, HardenedBSD, PHP, OpenSSH, StrongSwan, Suricata and Syslog-ng amongst others.

Please note that Let's Encrypt users need to reissue their certificates manually after upgrading to this version to fix the embedded certificate chain issue with the current signing CA switch going on.

The mail backup plugin is currently not available pending a response from the maintainer. Users are advised to avoid using it for the moment.
