+With ILIAS 8, the Technical Board has decided to replace the [`Superglobals`](https://www.php.net/manual/en/language.variables.superglobals.php)
 `$_GET`, `$_POST`, `$_COOKIE` and `$_REQUEST` with so called `SuperGlobalDropInReplacement` instances.
 These are `ArrayAccess` wrappers for the respective `Superglobals`. They contain the [`Refinery`](../Refinery/README.md)
 and run values on readout through the `->kindlyTo()->string()` `transformation` respectively.
 Furthermore, the `SuperGlobalDropInReplacement` should prevent that values in the `Superglobals` are manually
 assigned or modified/overwritten, because this violates the immutability of these values in the HTTP request.
 The general replacement of the `Superglobals` for some 3rd-Party-Libraries however leads to problems, because these
 require an `array` and no `ArrayAccess` object (currently known for `SimpleSAMLphp`). Therefore, there is the
-possibility to override the `Superglobals` via an ini setting in the `client.ini.php` file:
