+.. warning::
+  In this version of the provider, deprecated GCS hook's parameter ``delegate_to`` is removed from the following operators: ``GCSToS3Operator``, ``GlacierToGCSOperator`` and ``GoogleApiToS3Operator``.
+  Impersonation can be achieved instead by utilizing the ``impersonation_chain`` param.
