First official release of Eclipse RDF4J. Functionally this release will be equivalent to release 4.1.2 of OpenRDF Sesame (of which this project is the successor).
RDF4J represents a mature, production-ready code base. This particular release is the first to use new package naming and the occassional class rename.
A full step-by-step discussion of migration to RDF4J for existing users of Sesame is available in the Migration Guide on RDF4J.org.
