Release 1.3.1 is a pretty big change that adds o.a. a comment system. Including auto-registration.
Major parts of the code have been redone to support this. Since it has been quite some time since the last major update the changes are too much to detail.
A major change is that the Swiftfire directory in Application Support now has one more level added to it. This allows multiple instances of Swiftfire to run on the same server, each with its own top level subdirectory. For example a production and development version can be run in parallel (though on different ports of course)
Release 1.3.1 fixed a bug that was in release 1.3.0 which could occasionally crash the server.
This release has now run more than a month without stability issues on our own server.
