xtb version 6.4.1 released

We released a new version of xtb with a significantly improved memory footprint for large scale calculations and improved parallelisation for frequency calculations. The parallel evaluation of hessians with GFN-FF is now possible, overall we improved the stablility of the parallelisation which was slightly degraded in version 6.4.0. For xTB calculations the required OMP_STACKSIZE has been significantly reduced by restructuring the integral evaluation slightly.

Also, this version of xtb now supports the COSMO/CPCM solvation model using the ddPCM library.

DFT-D4 version 3.2.0 released

We released a new version of DFT-D4 further expanding the functionality of the Python API and the integration with QCEngine and ASE. In this process we simplified the installation of the Python extension module which should now also be possible with pip. The DFT-D4 program can now also calculate pairwise resolved dispersion energies, both for the pairwise additive and pairwise non-additive contributions to the total dispersion energy.
