  We describe the new version (v2.73y) of the code HFODD which solves the
nuclear Skyrme Hartree-Fock or Skyrme Hartree-Fock-Bogolyubov problem by using
the Cartesian deformed harmonic-oscillator basis. In the new version, we have
implemented the following new features: (i) full proton-neutron mixing in the
particle-hole channel for Skyrme functionals, (ii) the Gogny force in both
particle-hole and particle-particle channels, (iii) linear multi-constraint
method at finite temperature, (iv) fission toolkit including the constraint on
the number of particles in the neck between two fragments, calculation of the
interaction energy between fragments, and calculation of the nuclear and
Coulomb energy of each fragment, (v) the new version 200d of the code HFBTHO,
together with an enhanced interface between HFBTHO and HFODD, (vi) parallel
capabilities, significantly extended by adding several restart options for
large-scale jobs, (vii) the Lipkin translational energy correction method with
pairing, (viii) higher-order Lipkin particle-number corrections, (ix) interface
to a program plotting single-particle energies or Routhians, (x) strong-force
isospin-symmetry-breaking terms, and (xi) the Augmented Lagrangian Method for
calculations with 3D constraints on angular momentum and isospin. Finally, an
important bug related to the calculation of the entropy at finite temperature
and several other little significant errors of the previous published version
were corrected.
