Release of the Dalton2020 suite

[magnus]

Dear Dalton and LSDalton users,

The Dalton author group is happy to announce the release of the Dalton2020 suite.

New highlighted features in Dalton:

• MC-srDFT, the first public release of a new hybrid model for combining long-range MCSCF with short-range DFT functionals
• Core-valence separation (CVS) approximation for CC calculations of core-excited states
• New features available through the Polarizable Embedding library (PElib)
  • Polarizable density embedding (PDE) for HF, DFT, and CC methods
  • Cubic response properties using PE-DFT and PDE-DFT
  • Effective external field (EEF) for all dipole properties

New highlighted features in LSDalton:

• Derivatives with the OpenRSP library v1.0.0
  • open-ended electric dipole and geometrical derivatives at the Hartree-Fock level
  • selected derivatives also at the DFT level with the XCFun/XCint libraries
  • some functionality for single residues of electric dipole properties at the Hartree-Fock level
  • mediation of matrix operations with the QcMatrix library
• Python bindings generated using CFFI in API-mode
• Derivative integrals/integral components for general-order electrostatic potentials

We refer to the (Dalton and LSDalton) changelogs for a full list of additions, changes, and fixes that are part of this release. See the Dalton and LSDalton README files for information about how to download and build the programs.
