..  versionadded:: 11.4

..  versionchanged:: 12.0
    Due to the integration of EXT:recordlist into EXT:backend the namespace of
    the event changed from
    :php:`\TYPO3\CMS\Recordlist\Event\ModifyRecordListHeaderColumnsEvent`
    to
    :php:`\TYPO3\CMS\Backend\RecordList\Event\ModifyRecordListHeaderColumnsEvent`.
    For TYPO3 v12 the moved class is available as an alias under the old
    namespace to allow extensions to be compatible with TYPO3 v11 and v12.
