 - The default values of the parameters in :php:func:`set_cookie()` and :php:meth:`CodeIgniter\\HTTP\\Response::setCookie()` has been fixed. Now the default values of ``$secure`` and ``$httponly`` are ``null``, and these values will be replaced with the ``Config\Cookie`` values.
 -  ``Time::__toString()`` is now locale-independent. It returns database-compatible strings like '2022-09-07 12:00:00' in any locale.
+- The Validation rule ``Validation\Rule::required_without()`` and ``Validation\StrictRules\Rule::required_without()`` parameters have been changed and the logic of these rule has also been fixed.

 ======
 
 -  ``Time::__toString()`` is now locale-independent. It returns database-compatible strings like '2022-09-07 12:00:00' in any locale. Most locales are not affected by this change. But in a few locales like `ar`, `fa`, ``Time::__toString()`` (or ``(string) $time`` or implicit casting to a string) no longer returns a localized datetime string. if you want to get a localized datetime string, use :ref:`Time::toDateTimeString() <time-todatetimestring>` instead.
+- The logic of Validation rule ``required_without`` has been changed to validate each array item separately when validating fields with asterisk (``*``), and the method signature of the rule method has also been changed. Extending classes should likewise update the parameters so as not to break LSP.
