HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

Please check your Rails app for ‘config.i18n.fallbacks = true’.
If you’re using I18n 1.1.x and Rails (< 6.0), this should be 'config.i18n.fallbacks = [I18n.default_locale]'. If not, fallbacks will be broken in your app by I18n 1.1.x.
