Branches

1.x started in 2011. It has evolved by paying high attention to version compatibility.

2.x started in 2019 to make some significant improvements that also need new, simplified signatures. New features include

multiple sources for directed hyperedges
easy edge class definition using case classes thus easy definition of ADTs of edges
improved functional graph handling.

Shipment is due shortly after Scala 2.13.11 is published because this fix will help to further simplify user code.

Roadmap

Complete migration of random graphs for 2.x.
Investigate whether and how the JSON module should be retained and migrated to 2.x or dropped. Migrate it if needed.
Remove internal State by possibly also changing node references to IDs.
Add support for algorithms by enrichment that use fluent properties.
Reimplement immutable graphs to be based on a persistent data structure.
