Internationalization (i18n) is now part of Strapi core instead of a plugin. The locale parameter sent to Content Manager changes from plugins[i18n][locale] in v4 to locale in v5.

Internationalization (i18n) is now part of the Strapi core and no longer a plugin, and this impacts how some parameters are sent and accessed. This also means you should not use or depend on the old @strapi/plugin-i18n package in your project, it is now natively included.

Breaking change description#

In Strapi v4

Content Manager sends the following parameter when accessing a locale: plugins[i18n][locale].

In Strapi 5

The parameter sent to the Content Manager is now just locale.
