Virtuoso 7.0.0 is the stable release of the open source edition of the new Virtuoso engine.

An immediate benefit of this release is a massive increase in performance and scalability.

Additional features include newer versions of the ODS application suite; support for a JDBC 4.1 driver; new DAV API and DETs; an upgraded Conductor; upgraded Facet Browser; SQL fixes (transitive closure, optimizer, XPath); and the Virtuoso-specific query optimizer hint, ASSUME.

Virtuoso's RDF engine gains support for SPARQL 1.1 BIND and VALUES clauses, Update protocol, and functions and aggregates; various optimizations; connectors for Jena 2.10.x and Sesame 2.7.x; and optional pretty-printing of TTL output. Fixes address OPTION clauses for SPARQL-FED; scalability of graph-level security; transitivity; inferencing; and property paths.
