Version 4.10.1 is a bugfix release, not needed by most users. It fixes the syslog-ng container and platform support in some less common situations. Before you begin I assume that most people are lazy and/or overbooked, just like me. So, if you already have syslog-ng 4.10.0 up and running, and packaged for your platform, just skip this bugfix release. What is fixed? You can now compile syslog-ng on FreeBSD 15 again.
