- New and numerically stable procedure for elimination/freezing of orbitals at SCF level. Author: T. Saue.
- New ”.MVOFAC” option in *KRMC input section. Author: H. J. Aa. Jensen.
- New easier options for point charges in the .mol file: “LARGE POINTCHARGE” or “LARGE NOBASIS” (the two choices are equivalent).
- Added the RPF-4Z and aug-RPF-4Z basis sets for f-elements to the already existing files with sets for s, p and d elements. Deleted the aug-RPF-3Z set as that was not an official set.
- Write out effective Hamiltonian in Fock space coupled cluster to a file for post processing. Can be used with external code of Andrei Zaitsevskii (St. Petersburg).
- Provided memory counter for RelCC calculations, what is suitable for memory consuming large scale Coupled Cluster calculations. See the web-documentation.
- Updated basis_dalton/ with basis set updates in the Dalton distribution:
- fix of errors in Ahlrichs-pVDZ (several diffuse exponents were a factor 10 too big)
- fix of errors for 2. row atoms in aug-cc-pCV5Z
- added many atoms to aug-cc-PVTZ_J
- added many Frank Jensen “pc” type basis sets
- added Turbomole “def2” type basis sets
- Fixed errors for quaternion symmetries in 2-electron MO integrals used in CI calculations with GASCIP. It is now possible to do CI calculations with GASCIP for C1 symmetry (i.e. no symmetry).
- Fixed the p exponents for Na in the dyall 4z basis sets to match the archive. The changes are small so should not significantly affect results.
- Fixed compilation of XCFun on Mac OS X High Sierra.
- Fixed error for parallel complex CI or MCSCF with GASCIP
- .SKIPEP is now default for KR-MCSCF, new keyword .WITHEP to include e-p rotations
- restored integral screening behavior from DIRAC15
- DIRAC16 release.
- RELCCSD expectation values aka first-order unrelaxed analytic energy derivative. For more information, see J. Chem. Phys. 145 (2016) 184107 as well as test/cc_gradient for an example.
- Calculation of approximate dipole intensities together with the excitation energies in Fock space CC. See test/fscc_intensities for an example.
- Improved start potential for SCF: sum of atomic LDA potentials, generated by GRASP.
- Negative denominators (e.g. appearing in core ionized systems) accepted in RELCCSD
- AOFOCK is now default if at least 25 MPI nodes (parallelizes better than SOFOCK). .AOFOCK documented.
- Error corrections and updates in isotope properties for the following atoms:
- Br isotope 2: quadrupole moment .2620 -> .2615
- Ag isotope 2: magnetic moment .130563 -> -.130691 (note sign change)
- In isotope 2: quadrupole moment .790 -> .799
- Nd magnetic moments of isotopes 4 and 5 were interchanged: -0.065 -> -1.065 and -1.065 -> -0.065
- Gd: quadrupole meoments of isotopes 4 and 5 updated: 1.36 -> 1.35 and 1.30 -> 1.27
- Ho isotope 1: quadrupole moment updated 3.49 -> 3.58
- Lu isotope 2: quadrupole moment updtaed 4.92 -> 4.97
- Hf isotope 1: mass was real*4, not real*8, thus 7 digits instead of 179.9465457D0 (i.e. approx 179.9465)
- Ta isotope 1: quadrupole moment added 0.00 -> 3,17
- Tl isotope 1: nuclear moment 1.63831461D0 -> 1.63821461D0 (typo, error 1.d-4)
- Pb isotope 3: nuclear moment 0.582583D0 -> 0.592583D0 (typo, error 1.d-2)
- Po isotope 1: nuclear moment added: 0.000 -> 0.688
- Faster Dirac compilation due to implemented OBJECT libraries (requires CMake of version at least 2.8.10).
- Run benchmark tests and only benchmark tests with “ctest -C benchmarks -L benchmark”.
- Change any tab character in coordinate specifications in .mol file to a blank. (tab characters have been reported to cause errors in reading coordinates).
- Added OPENBLAS in search list for blas and lapack libraries.
- Made keyword .X2Cmmf case insensitive.
- Cache compiler flags.
- Bugfix: MCSCF and GASCIP was not correct for odd number of electrons.
- Bugfix: now .CASSCF works again for KRMSCF input.
- Bugfix: KRMSCF was not converging is some cases (problem reported by Miro Ilias for Os atom).
- Bugfix: “all” keyword for ”.GAS SHELLS” was not recognized (problem reported by Miro Ilias).
- Bugfix for numerical gradient when automatic symmetry detection: do no move or rotate molecule for finding highest possible symmetry because then the numerical gradient will not be correct (problem reported by Miro Ilias).
- Bugfix for spinfree X2Cmmf and linear symmetry.
- Bugfix: restored “make install” target.
- Bugfix: Test reladc_fano does not report failure if Stieltjes is deactivated.
- FanoADC-Stieltjes: Calculation of decay widths of electronic decay processes.
- Better convergence for open-shell calculations, using .OPENFAC 0.5 as default. Final orbital energies are recalculated with .OPENFAC 1.0, for IP interpretation.
- Performance improvement for MP2 NO: only transform (G O|G O) integrals instead of (G G|G G).
- Geometry optimization with xyz input.
- Performance improvements for determinant generation in GASCIP.
- Use Kramers conjugation on CI vectors (cuts time for CI in half for ESR doublets).
- ANO-RCC basis: Fixed Carbon basis set (wrong contraction coefficients, see [MOLCAS ANO-RCC](http://www.molcas.org/ANO/).
- ANO-RCC basis: Modified the 3 Th h-functions by replacing them with the 3 Ac h-functions to Th. (A mistake was made in the original work when the 3 Th h-functions were made, and this has never been redone. They are too diffuse, exponents (0.3140887600, 0.1256355100, 0.0502542000) for Th, Z=90, compared to (0.7947153600, 0.3149038200, 0.1259615200) for Ac, Z=89, and (0.8411791300, 0.3310795400, 0.1324318200) for Pa, Z=91. We have selected to just replace the 3 Th h-functions with those from the Ac basis set, because the Ac g-functions are quite close tot he Th g-functions, closer than Ac g-functions, and therefore differences in results compared to optimized Th h-functions should be minimal.) Thanks to Kirk Peterson for pointing out the Th problem on http://daltonforum.org.
- Fixed reading of ANO-RCC and ANO-DK3 basis sets from the included basis set library.
- Update PCMSolver module to its [1.0.4 version](https://github.com/PCMSolver/pcmsolver/releases).
- Do not write Hartree-Fock in output if it is a DFT calculation, write DFT.
- Fix a bunch of problems where the number of arguments of the call does not match the subroutine definition (submitted by Martin Siegert).

- Added OpenBLAS to default blas search list.
- Fixed misleading error message for .OPEN SHELL input.
- Workaround for CMake warning about nonexistent run_pamadm target.

- Fixed minor issues to allow compilation using IBM XL Fortran compiler (thanks to Bob Walkup, IBM).
- Update PCMSolver module to its [1.0.3 version](https://github.com/PCMSolver/pcmsolver/releases).
