Description: 

In Drupal 7, PHP-file based quick string overrides were located in the global $conf['locale_custom_strings_' . $langcode] array. In Drupal 8, the $conf array is used for global config() overrides only, so this was moved out to global $settings['locale_custom_strings_' . $langcode]. It can still be set from settings.php.

The structure of the array did not change.

This change only affects you if you use the $conf['locale_custom_strings_' . $langcode] overrides in your settings.php before.
