Unity version

Could consider updating Unity to at least the latest version of the Unity 2018.4 stream, if not to 2020 or 2019 LTS

Upgrading to a later Unity stream like 2019 LTS (Long Term Support) or the latest 2020 version would enable better integration for unit tests and other such tests. Furthermore, 2018 LTS is going to hit end of life in the spring, so starting that migration may not be a terrible idea.
