-    - `classes` option added to `item` allow custom classes on the `.govuk-checkboxes__item` element

-    - `asList` option added the root `params` object to allow setting of the `.govuk-checkboxes` and `.govuk-checkboxes__item` element types
-    - `children` option added to `item` allowing the sending in of prerendered child checkboxes (allowing the creation of tree structures through recursion) -#}
