fixes:
- |
Fixed an issue with the :func:`~qiskit.visualization.circuit_drawer`
function and :meth:`~qiskit.circuit.QuantumCircuit.draw` method of
:class:`~qiskit.circuit.QuantumCircuit`. When displaying a ``measure``
instruction targeted on a classical bit instead of a register, using
the ``latex`` drawer option, the drawer would fail.
- |
Fixed an issue with the :func:`~qiskit.visualization.circuit_drawer`
function and :meth:`~qiskit.circuit.QuantumCircuit.draw` method of
:class:`~qiskit.circuit.QuantumCircuit`. With any of the 3 drawer
options, ``mpl``, ``latex``, or ``text``, if a gate with a classical
condition was encountered that was conditioned on a classical bit
without a register, the drawer would fail.

:class:`~qiskit.circuit.QuantumCircuit`. With any of the 3 drawer
options, ``mpl``, ``latex``, or ``text``, if a gate with a classical
condition was conditioned on the same classical bit as a ``measure``
and the bit that the measure targeted did not have a register, the
drawer would fail.
