Changes:

• Make compatible with Unity builds

Changes:

• Improve support for compilation on Windows (MSVC)
• Update address in license

Changes:

• Various bugfixes and improvements

Changes:

• Added parameter sets trans3d-0-1 (Sc, Ti, Fe, Co, Ni) and borg-0-1 (B)
• Enforce "C" locale for Molden files
• Various bugfixes and improvements

Changes:

• Various bugfixes and improvements

Changes:

• Excited-state calculations with NDDO-CIS and TD-DFTB
• Added a binary for the calculation of IR and UV/Vis spectra of trajectories
• Orbital steering calculations possible with binary (using a single system, single point) and Python bindings (can handle an individual system and systems along a trajectory)
• Can now set symmetry number for thermodynamics calculation
• Added density matrix RMSD SCF convergence check
• Calculate atomic second derivatives
• Removed Sparrow-specific Python bindings in favour of the more general Core::Calculator Python bindings
• Added Python bindings for excited-state calculators; see Utilities for more infos on them
• Added patching functionality in DFTB embedded parameters, i.e. if the znorg-0-1 parameter set is chosen, then parameters are automatically sorted out between znorg-0-1 and mio-0-1 (patch parameters available: znorg-0-1, hyb-0-2)
• Fixed bug causing an instability in the calculation of the gradients (and Hessian matrix) in DFTBx
• Added conanfile.py for easier compilation and dependency-handling by Conan
• Made Sparrow relocatable by embedding the parameters in the compiled program; it is still possible to give parameter files externally
• Multiple bug fixes and stability fixes
• Improved testing

Changes:

• Corrected bug in setting the element collection in Python bindings
• Added missing include statement that prevented compilation on GCC 10.0.1.

Changes:

• Calculate thermochemical properties
• Explicitly symmetrized Hessians
• Generation of molden input files for molecular orbital visualization
• General stability/performance improvements
• Access to the calculations and molden file generations also through SCINE Core::Calculator Python bindings
• Addition of 3ob-3-1 parameters sets for DFTB. Spin constants are extracted from Christof Köhler, Berücksichtigung von Spinpolarisationseffekten in einem dichtefunktionalbasierten Ansatz, PhD thesis, Departement Physik der Fakultät für Naturwissenschaften an der Universität Paderborn, 2004
• Addition of automatic linking to MKL/LAPACK/BLAS through Eigen
• Various bugfixes and improvements
