OpenLink Software is pleased to announce a new release of Virtuoso,
Open-Source Edition, version 5.0.8.

This version focuses on performance optimizations and speed enhancements:

+ SQL compiler is now re-entrant
+ Self-Join optimizations exposed at JDBC Driver level (as was already the
case with ODBC)
+ SPARQL engine and SPARQL-BI extension optimizations have been merged
+ TriG serialization format for RDF is now supported alongside RDFa, N3,
Turtle, and RDF/XML
+ Additional Sponger Cartridges for Digg, FriendFeed, and CrunchBase
+ Improved graph quality and fidelity from existing Cartridges (especially
Freebase, eBay, Amazon, Google, Yahoo, and many others)
+ Improved handling of and bug fixes relating to the `OPTIONAL' SPARQL keyword
+ Self-Dereferencing fixes (e.g., Sponger was not properly de-referencing
its own Proxy URIs)

On the ODS front, the following have been addressed:

+ More flexible Mapping service model based on new OAT-based Mapping
Control (which also includes a "province" locator)
+ Improved SyncML integration with Briefcase folders
+ Gem URL fixes for Atom, RSS, and RDF feeds

For more details, see the release notes:
