+================================================================
+Breaking: #61822 - deprecated function getUniqueFields() removed
+================================================================
+
+See :issue:`61822`
+
+Description
+===========
+
+The function :code:`getUniqueFields()` from :code:`\TYPO3\CMS\Core\DataHandling\DataHandler` has been removed.
+The function is available in :code:`\TYPO3\CMS\Version\Hook\DataHandlerHook`.
+
+Impact
+======
+
+Extensions that still use the function :code:`getUniqueFields()` won't work.
+
+
+Affected installations
+======================
+
+A TYPO3 instance is affected if a 3rd party extension uses the removed function.
+
+
+Migration
+=========
+
+Replace all calls to :code:`\TYPO3\CMS\Core\DataHandling\DataHandler::getUniqueFields()`
+with calls to :code:`\TYPO3\CMS\Version\Hook\DataHandlerHook::getUniqueFields()`
