- Issues
- fix(#11910): algo.maxFlow follows relationship direction (direction argument, OUT default)
- openCypher: toString() of a time or datetime drops zero seconds and keeps trailing zeros of the fraction (10:00 / .500 where Neo4j 5 gives 10:00:00 / .5)
- openCypher: shortestPath()/allShortestPaths() from a node to itself answer a 0-length path even for [:E*1..] (Neo4j 5 refuses the statement)
- fix(#11912): openCypher toString() of times and datetimes always prints seconds and trims the fraction, as Neo4j does
- perf(#11891): answer a one-hop COUNT { }, EXISTS { }, pattern predicate and size() of a pattern comprehension off the edge list
- perf(#11904): a pattern with an unlabelled node is planned by the optimizer from an index on a labelled one
- fix(#11913): a shortest path from a node to itself answers only a minimum of zero
- SQL: a bound list of RID strings is refused as a SELECT/TRAVERSE target (Cannot use collection as target), though a single bound RID string is accepted
- openCypher: counting the relationships of a type is O(relationships) (640,000: 69 ms, 234 ms with labelled endpoints) while SQL count(*) FROM <edge type> answers in 0.6 ms
- Conditional UPDATE ... WHERE and openCypher MATCH ... WHERE ... SET are not atomic: a commit landing between the read and the write is overwritten and both statements report the update
