Sidenote
Unfortunately, due to the project being completed and not having updates in a while (and it just being an old university project, really), I'm left as the only active maintainer, which means I can only compile the jar file for the linux client.
Hopefully this is interesting enough to try and compile it on your own (the main reason there were different builds for different OSes was the fxml GUI available, meaning this linux jar build should still work if you just use the CLI option).
If that's too daunting, although I haven't tested this, the previous client version should still work with the new server and client, as nothing of substance really changed (but a minor was justified by the JDK bump and license change).
