 ### Added
 
 - Added `libcasm.clusterography.make_custom_cluster_specs`, which takes a custom site filter function to generate a ClusterSpecs with custom_generators generated with the custom site filter. This approach allows creating a ClusterSpecs that is customized, as with a custom site filter, but still works to save/load without to_dict/from_dict needing the custom filter. 
 - Added `make_canonical_local_configuration`, `make_distinct_local_cluster_sites`, and `make_distinct_local_perturbations` to `libcasm.enumerate`.
 - Added `local_symgroup_rep` to `libcasm.configuration.Supercell`.
 - Added `distances` and `phenomenal_distances` to `libcasm.clusterography.Cluster`
+- Added `libcasm.local_configuration` for local configuration enumeration and comparison.
+- Added `libcasm.enumerate.ConfigEnumLocalOccupations` for local configuration enumeration.
+- Added `make_supercells_for_point_defects`, `find_optimal_point_defect_supercells`, `make_required_sites`, `plot_point_defect_supercell_scores`, and `print_point_defect_supercell_info` to `libcasm.enumerate` to help find optimal supercells for calculations.
