You are looking at our brand new Automatic Updater which you can run like any normal jar on our website.
However when there is a new version available either on the version you predefine or latest it will
automaticly update your server to that version on each restart. The jar is ran in place of your usual
jar, just make sure to configure the wanted version and jar type correctly though the
serverjars.properties which is automatically created when you first run the jar.
