… loads GraphObjectManager's dirty-tracking session kept a full JSON snapshot of every node ever loaded, for the life of the application. In a running appliance it held 325 MB after 29 documents. 0.0.85 stores shape, ids and hashes instead, bounds the session, and makes it thread-safe. 0.0.85 also makes a saved relationship list authoritative whether or not the view was loaded first.

Drivine's session held a JSON copy of every node ever loaded, for the life of the app. 0.0.85 bounds it.
Before
GraphObjectManager's session kept full snapshots, embeddings and text included, and never released them: 325 MB of a 518 MB live heap after ingesting 29 documents into an appliance.Now
drivine.query.session-max-entries); thread-safe. Dirty tracking across transactions still works.Behaviour change to be aware of: a saved relationship list is now authoritative even if the view was not loaded first. Relationships of that type to targets not in the list are removed.
Key change
Tests: 2,674 tests across all modules, 0 failures (Neo4j containers), run on JDK 21 against 0.0.85. No source changes were needed; nothing here calls the constructors or
