* Fix for open-shell Brueckner orbital self-consistency * Fixes for single precision unrestricted density fitting * Fix for Brueckner self-consistency rotation matrix
What's Changed * Adds CCSDt', where the T3 amplitudes have all indices in an active space. * Fixes the conversion between spin types in cases where there are frozen or active orbitals. * Changes to the internals of the `Ansatz` class to improve generalisability. * Improves the `Space` interface and internals.
