Improve the decomposition of multi-controlled Pauli-X and Pauli-Y rotations on :math:`n`
controls to :math:`16n - 40` CX gates, for :math:`n \geq 4`. This improvement is based
on `arXiv:2302.06377 <https://arxiv.org/abs/2302.06377>`__.

:meth:`.DAGCircuit.substitute_node` gained a ``propagate_condition`` keyword argument that is

Deprecate duplicate gate methods on :class:`.QuantumCircuit`. The rule applied is that
