Hi,
Last weekend syslog-ng 3.9.1 became available on FreeBSD in the sysutils/syslog-ng-devel port. The default syslog-ng port, sysutils/syslog-ng still points to syslog-ng 3.7.
If you use syslog-ng on FreeBSD, please test 3.9.1 as I plan to promote 3.9.1 as the default syslog-ng version in ports. (I am only aware of a single problem when upgrading from earlier versions to 3.9.1, but that's Linux only:

Let me know, if you run into any troubles with 3.9.1, so it can be fixed before the change.
