Thread message metadata is episode metadata
Metadata on a thread message now behaves the same as metadata added through
graph.add. Zep projects it onto the facts, entities, and summaries derived
from the message, graph search filters on it, and source-based access control
evaluates it. Message metadata accepts at most 10 keys with scalar or
array-of-scalar values. On an update, a key set to null is removed.
Batch ingestion honors the default ontology setting
Batch ingestion ignored the setting that disables the default ontology, so the
same content could receive different entity and edge types when it entered
through a batch. Batch ingestion now applies the setting in the same way as
graph.add and thread.add_messages.
Self-referencing facts are kept
Extraction dropped a fact whose source and target are the same entity, which lost personal states and routines. Those facts are now kept in the graph.
Ingestion Traces replace reasoning traces
The debug mode Reasoning tab is now Ingestion Traces. A trace explains why each traced ingestion stage produced its decision. Tracing does not change the stage output or the graph. Zep retains traces for 30 days.
