This release is recommended for all users and includes improved support for calculating forces, better GPU support, updated build recipes and documentation for many machines, and a broad range of other useful improvements.
This major release includes an important change in the default driver behavior, significantly expanded GPU support including fully GPU accelerated LCAO/Gaussian-basis set wavefunction support for both molecular and solid-state systems, improved GPU configuration options, a new fast spin-orbit implementation based on exact spin integration, a stochastic reconfiguration-based wavefunction optimizer for large parameter sets, self-he
