Migration to i18next-vue v4.x

There are few breaking changes migrating from i18next-vue version 3 to version 4.

If you are migrating from older versions, see Migration to i18next-vue v3.x first.

If you are still using the i18nOptions component options, it makes sense to upgrade to version 3 first. Then iteratively migrate all its uses to useTranslation() with its new parameters. Then you can easily upgrade to 4.x.

Breaking changes

• removed support for i18nOptions (Options API)
  • You can use useTranslation() with its new parameters for most of these use-cases instead.
  • Removed the legacyI18nOptionsSupport: true plugin option
