Sesame 2.7.0-beta1
==================

This is the first beta release for 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 at
https://bitbucket.org/openrdf/sesame/wiki/Home.

Some of the highlights of this release:

 * Sesame Maven artifacts for this release are now available in Maven Central
 * 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.
 * Multiple large improvements in the OpenRDF Workbench, including support for
   basic HTTP authentication, paging support of query results, and bookmarking
   of queries.
 * Rio parsing/writing support for the N-Quads format
 * HTTPRepository now supports background parsing/concurrent reading of results
 * Several improvements in SPARQL 1.1 support to bring up to date with the
   Proposed Recommendation published on November 8.

See the Changelog below for a complete listing of all fixed issues. More
details can be found in the Sesame issue tracker at
http://openrdf.atlassian.net/ .

As this is a beta-release, we are eager for you to try it out and test it, but
we advise not to update your production systems to this release just yet. We
would welcome any feedback you might have, you can use the Sesame Discussion
mailinglist for this purpose:
