+    Loading library :class:`~.qiskit.pulse.ScalableSymbolicPulse` objects with
+    complex ``amp`` parameter from
+    qpy files of version 5 or lower (Qiskit Terra < 0.23.0) is now deprecated.
+    Following the removal in Qiskit 1.0.0, complex ``amp`` will be automatically
+    converted to float (``amp``,``angle``). The change applies to the pulses:
+
+    * :class:`~.qiskit.pulse.Constant`
+    * :class:`~.qiskit.pulse.Drag`
+    * :class:`~.qiskit.pulse.Gaussian`
+    * :class:`~.qiskit.pulse.GaussianSquare`
