This is a small update from 2.2.0 which fixes a few leftover bugs and improves some small points. Check out what's new at [NewFeatures221]. You can find it in the download area. It comes complete with a ready-to-run Jetty container for quickly getting up and running (start.bat/start.sh for starting the server, stop.bat/stop.sh for stopping it) on port 8888. The war file (in the webapps directory) can be used in any other servlet container (like Tomcat) as well.
Updating is fairly easy, as database changes are now applied automatically rather than having to be done manually.
