General availability of type hierarchies
Entity type hierarchies and edge type hierarchies are now generally available. You can now set entity_type_hierarchy and edge_type_hierarchy in a project ontology or a graph ontology without a request for access. Before, the hierarchies were in closed beta, and Zep enabled them only for select accounts.
Entities of custom types with properties
Zep now keeps an extracted entity of a custom entity type with properties when the episode has no facts about the entity. Zep stores the extracted property values on the entity node. Before, Zep dropped an entity with no facts, and its property values were lost.
