 - **Toolbar:** Fixed a bug in the Routes panel where only the first route parameter was converted to an input field on hover.
 - **Testing:** Fixed a bug in ``FeatureTestTrait::withRoutes()`` where invalid HTTP methods were not properly validated, thus passing them all to ``RouteCollection``.
 - **Validation:** Rule ``valid_cc_number`` now has the correct translation.
+- **Validation:** Fixed a bug where rules did not fire for array elements missing a key when using wildcard fields (e.g., ``contacts.friends.*.name``).
 - **View:** Fixed a bug where ``View`` would throw an error if the ``appOverridesFolder`` config property was not defined.

+.. note:: When validating nested array data with the wildcard ``*`` syntax, use ``required``,
+    ``required_with``, or ``required_without`` to ensure that every array element is checked
+    for the presence of a key. Without one of these rules, elements whose key is absent are

 .. note:: You can also use any native PHP functions that return boolean and
     permit at least one parameter, the field data to validate.
