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 includes a new binary RDF serialization format. This format has been derived
from the existing binary tuple results format. It's main features are reduced parsing
overhead and minimal memory requirements (for handling really long literals, a.o.t.).

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.
