Unify maintenance release 4.1.5
This release focuses on improving user experience with graph v2.
Previously, graph v2 cant be queried if the relationship had no properties. The user was able to build the graph model but not query it. Now, the user is able to query a graph whose relationships don't have properties.
Users that previously built a graph without relationship properties, will need to publish the pipeline to rebuild the graph.
A graph whose relationships dont have any property can be built in the following way, simply add a flow into the graph v2 node with only the required columns (Node From, Node To, Edge type)
