Will it be fine to use 2017.2 for the Unity 2.0 course?
Check out the last video from Ben–I believe he said it was specifically designed around 2017.2. That being said–despite the warnings I have been using 2017.2 for the Unity 1 course. It just takes a few things here and there I have to change but it wasn’t super tough to figure out with the debug message and google :).
