Sesame 2.3.0 has major improvements on three subjects: NativeStore performance, query optimization and the SeRQL query language.

The NativeStore's performance for processing updates has been improved. Updates in general should be a bit faster now, but the removal of (small sets of) statements has been improved dramatically.

The query optimizer has been improved for various query types. Queries with nested unions, nested optional joins and/or result ordering can now be processed in a potentially more efficient way, resulting in better query performance.

The SeRQL query language has been extended with new syntax. First of all, all of SPARQL's functionality is now also available in SeRQL. This includes Order By, Union of path expressions, SameTerm, Str, LangMatches, Regex and Reduced. Also, the IN-operator can now also be used on a list of values to express that a variable must be bound to one of these values.

Finally, there's the usual set of bug fixes.

We have opened two new mailing lists for Sesame and related software on SourceForge. These new mailing lists will be replacing the existing ones as well as the forum on openrdf.org.

The sesame-general mailing list is meant for questions and discussions about Sesame and related software. It replaces both the forum on openrdf.org (which some people have trouble accessing as of lately) as well as the (hardly used) sesame-devel lists.

The sesame-announce mailing list will replace the current sesame-interest list. This is mostly a kind of rename for the list to clarify it's role. All subscribers of the old list will be moved to the new list by us.
