Release Notes: Graph Data Science 1.6.3

Release Date: 22 July 2021

GDS 1.6.3 is compatible with Neo4j 4.0, 4.1, 4.2, and 4.3 but not Neo4j 3.5.x. For a 3.5 compatible release, please see GDS 1.1.6.

Breaking changes

• Remove the sharedUpdater parameter from gds.alpha.ml.linkPrediction and gds.alpha.ml.nodeClassification.

Bug fixes

• Fixed a bug which affected gds.nodeSimilarity.write and gds.alpha.knn.write when being executed in combination with a nodeLabels filter. The bug either led to an exception or to wrong results due to an incorrect mapping between internal and Neo4j node ids.
• Fixed a bug in seeded NodeClassification and LinkPrediction which lead to non-deterministic behaviour.
• Fixed a bug where gds.nodeSimilarity.[write|mutate] and gds.beta.knn.[write|mutate] wrote duplicate relationships if the input graph is undirected.
• Fixed a bug in gds.beta.knn where negative values in node properties of type float arrays failed when returning the similarityDistribution.

Improvements

• Lower memory footprint for LinkPrediction and NodeClassification.
