Qiskit Nature 0.6.1

Bug Fixes

• The ActiveSpaceTransformer would sometimes set the wrong number of active particles because of a flawed integer rounding. This has now been fixed.

• Fixes a formatting issue when printing an ElectronicStructureResult which contains values in extracted_transformer_energies

• The ElectronicStructureProblem.reference_energy is now properly propagated to the ElectronicStructureResult.hartree_fock_energy.

• Fixes a regression in the performance of the map() method

• Compatibility fix to support optional sparse install under Python 3.11.

• Fixed the support of use_pauli_sum_op in the UCC and UVCC classes as well as their extensions. This requires version 0.24 or higher of the qiskit-terra package.
