Sesame 2.7.0 
============

We are very pleased to announce the first stable release of Sesame 2.7. 

Sesame 2.7 is a major update of the framework, incorporating several
improvements in the core APIs, as well as numerous bug fixes, new features, and
useful improvements.

Since several core APIs (including the SAIL API and the Repository API) have
undergone changes, we urge both users of the framework and independent
implementors of SAIL backends to read the upgrade notes:

  http://openrdf.callimachus.net/sesame/2.7/docs/articles/upgrade-notes.docbook?view

Some of the highlights of this release:

* Sesame Maven artifacts for this release are now available in Maven Central
* Sesame has been officially updated to require Java 6
* SAIL API overhaul: introduction of SailConnection.begin() to explicitly
  indicate transaction start. See the upgrade notes for details.
* RepositoryConnection overhaul: setAutoCommit() replaced by begin(),
  isAutoCommit() replaced by isActive(). See the upgrade notes for details.
* The Model interface: an extension of Graphs with convenient methods for quick
  manipulation of collections of RDF statements in memory.
* Multiple large improvements in the OpenRDF Workbench, including support for
  basic HTTP authentication, paging support of query results, and bookmarking
  of queries.
* The Federation SAIL: configurable querying over federated Sesame stores.
* Rio parsing/writing support for the N-Quads format
* HTTPRepository now supports background parsing/concurrent reading of results
* The Rio Turtle parser has been updated to comply with the latest W3C Working Draft.
* 99.9% compliance with the SPARQL 1.1 Query Language W3C Recommendation.
* full compliance with the SPARQL 1.1 Protocol Recommendation, the SPARQL 1.1
  Update Recommendation, and the SPARQL 1.1 Graph Store HTTP Protocol
  Recommendation.
