- *
- * Beginning with MediaWiki 1.23, translation strings are stored in json files,
- * and the EXTENSION.i18n.php file only exists to provide compatibility with
- * older releases of MediaWiki. For more information about this migration, see:
- * https://www.mediawiki.org/wiki/Requests_for_comment/Localisation_format
- *
- * This shim maintains compatibility back to MediaWiki 1.17.
