##From v5 to v6
The config file has been removed. You can now define a fallback locale, set fallBackAny and handle custom behaviour for missing translations, via Translatable::fallback(). Take a look in the readme to learn how to specify the fallback behaviour you want.
The TranslationHasBeenSet event has been renamed to TranslationHasBeenSetEvent.
##From v2 to v3
In most cases you can upgrade without making any changes to your codebase at all. v3 introduced a translations accessor on your models. If you already had one defined on your model, you'll need to rename it.
