I have a question regarding backwards compatibility with .meta files. As they get modified when I migrate from 2018.4 to 2019.3. So I have the following scenario: Module Z: A Unity Package created with Unity 2019.3 which has some code and a prefab. Project Beta: A Unity Project using 2018.4 includes module Z through Unity Package Manager. Is there a problem doing this? Do you foresee any issues? I would like to know this because I need to share code between projects with different unity version and I want to avoid having 2 different versions of the module.
