To get the most out of this book

The majority of this book will focus on features and enhancements that apply to Unity 2019 and Unity 2020. Many of the techniques explored within this book can be applied to Unity 2018 projects and older, but some features may be different. These differences will be highlighted, where applicable.

It is worth noting that the code it is supposed to work on Unity 2020 but at the time of writing we could only test it on the alpha version. Additional incompatibilities may arise when Unity 2020 comes out of alpha.
