+    In the qiskit.pulse.channels package, ClassicalIOChannel class has been added
+    as an abstract base class of MemorySlot, RegisterSlot, and SnapshotChannel.
+
+    The qiskit.pulse.transforms.canonicalization.pad method does not introduce
+    delays to any channels which are instances of ClassicalIOChannel.
+
+    In qiskit.pulse.instructions, the constructors to SetPhase, ShiftPhase,
+    SetFrequency and ShiftFrequency now throw a PulseError if the channel parameter
+    is not of type PulseChannel.
