Release Notes
============= 

We are very proud to announce the release of Sesame 2.4.0. This is a major new release
featuring support for SPARQL 1.1 Query. 

Sesame 2.4.0 implements all features of SPARQL 1.1 Query as outlined in the October 14
W3C Working Draft (see http://www.w3.org/TR/2010/WD-sparql11-query-20101014/), with the
exception of basic federated query. SPARQL 1.1 for Sesame is developed by Ontotext
(http://www.ontotext.com/) in cooperation with Aduna (http://www.aduna-software.com/).

The list of new SPARQL query features includes:

* Use of expressions in the SELECT clause

* Aggregates (COUNT, MIN, MAX, AVG, SUM, GROUP_CONCAT), HAVING and GROUP BY

* Property paths 

* Subqueries

* Negation: (NOT) EXISTS and MINUS

* Set membership: (NOT) IN

* Conditionals: IF

* Various new builtin functions: COALESCE, BNODE, IRI, isNumeric, strLang, strDt

Apart from this impressive array of new query language features, Sesame 2.4.0 also
implements a number of bug fixes and improvements, including scalability and performance
improvement in the Native store.
