Ontology validation of attributes in v4 node and edge add
The v4 graph.node.add and graph.edge.add methods now validate each custom attribute against your ontology. A node with attributes must have a label that matches an entity type. An edge with attributes must have a fact_name that matches an edge type. An attribute that the matching type does not define, or a value of the wrong type, returns an HTTP 400 error. Before, Zep accepted these attributes without validation.
Hyperedges and entity type hierarchies on BYOC
Hyperedges and entity type hierarchies are now on by default on BYOC. Each new project on a BYOC deployment uses hyperedges. To use hyperedges in an existing project, set hyperedges_enabled to true on the project.
Batch process task status documentation
Documentation of the batch.process task status for each batch status was added to the Batch API guide.
Per-kind ontology fallback documentation
Documentation of how a graph ontology uses the project entity types or edge types was added to the Customizing Graph Structure guide.
