It should definitely work on julia v1.4. In what way is it not working?  
To participate in the development of ControlSystems, we’d be happy to discuss in an issue on the repository or accept PRs 🙂

If you have any issues I would be happy to support you.  
But of course I would need some more info:  
On which operating system do you test? How did you install Julia?
