Sesame 2.5.0

We are very pleased to announce the release of Sesame 2.5.0. This is a
major new release with some very exciting features:

SPARQL 1.1 Query Language support

Sesame 2.5 features near-complete support for the SPARQL 1.1 Query
Language Last Call Working Draft[1], including all new builtin functions 
and operators, improved aggregation behavior and more.

SPARQL 1.1 Update support

Sesame 2.5 has full support for the new SPARQL 1.1 Update Working
Draft[2]. The Repository API has been extended to support creation of
SPARQL Update operations, the SAIL API has been extended to allow Update 
operations to be passed directly to the underlying backend
implementation for optimized execution.

Also, the Sesame Workbench application has been extended to allow easy
execution of SPARQL update operations on your repositories.

SPARQL 1.1 Protocol support

Sesame 2.5 fully supports the SPARQL 1.1 Protocol for RDF Working
Draft[3]. The Sesame REST protocol has been extended to allow update
operations via SPARQL on repositories. A Sesame server therefore now
automatically publishes any repository as a fully compliant SPARQL endpoint.

Binary RDF support

Sesame 2.5 implements a new binary RDF serialization format. This format 
has been derived from the existing binary tuple results format. Its main 
features are reduced parsing overhead and minimal memory requirements 
(for handling really long literals, amongst other things).

Sesame 2.5 SPARQL improvements have been made possible by Ontotext, in
cooperation with Aduna. We hope you enjoy the new features and look
forward to receiving your feedback.
