Sesame 2.7.4 
============

Sesame 2.7.4 is a maintenance release, fixing 24 issues. Among the highlights
are a new custom rule-based inferencer, support for Symmetric Concise Bounded
Descriptions in DESCRIBE queries, support for HTTP HEAD requests, and various
other fixes and improvement in parsers, query engine, and transaction handling. 

See the OpenRDF JIRA Changelog for a complete listing of all fixed issues:

NOTE: although this release is classified as a minor release (indicating
compatibility with earlier releases), users of SPARQL are advised of one change
that is not backward compatible with earlier releases: support for the '{min,
max}' property path length syntax has been removed from the SPARQL parser, in
accordance with its earlier removal from the official SPARQL specification. See
issue SES-1706. If you are currently using this particular syntax construct in
your SPARQL queries, you are advised to modify those queries before upgrading.

We would welcome any feedback you might have, you can use the Sesame Discussion
mailinglist for this purpose.
