Changes between successive published TkN databases. Counts distinguish additions, removals and modifications. Detailed changes can be inspected by nucleus, dataset, level and transition. Dataset, level and transition counts are separated into ENSDF and XUNDL changes for every release. Physical level properties introduced by a schema upgrade, including static magnetic-dipole and electric-quadrupole moments, remain visible; schema absence is distinguished from a missing measurement. Compact reports detail physical changes only. Uncertainties, limits, approximations and comments are counted as metadata. Legacy reports retain their original display and comment filter. Reports and the database may become available at different times while the history merge request is under review.
