Thanks Marko, To put a finer point on it, the issue is the viral nature of GPL and its effect on software that links to libraries released under its terms. While we understand this is an inconvenience for many of you, it is an extremely important legal issue that we are working with Neo4J to resolve. For a more thorough description of the reasoning behind this decision, please consult the following:
