[ANN] Apache Jena 3.1.0 released with Fuseki 2.4.0

[Andy Seaborne <an...@apache.org>]

We are pleased to announce the release of Apache Jena 3.1.0 together
with Fuseki 2.4.0.

This release of Jena includes features which were release candidates in
Jena 3.0.1.

In this release:

* In-memory transactional dataset
   contributed by Adam Soroka
   with thanks to the University of Virginia Library for
     providing the time for Adam to work on this.
   (RC in Jena 3.0.1)

http://jena.apache.org/documentation/rdf/datasets.html

This provides full isolation ACID transactions so multi-threaded
applications can use the transaction paradigm for working with in-memory
data.

* SPARQL extension for CONSTRUCT Quads (RC)
   contributed by Qihong Lin
   with thanks to the Google Summer of Code scheme
     for sponsoring Qihong on this project.
  (RC in Jena 3.0.1)

* New custom functions and aggregate functions
   Added:
   + afn:sprintf (contribution from Alessandro Seganti)
   + The XQuery/XPath Functions and Operators "math:" functions
   + Custom aggregates for stdev etc. (also STDEV etc as keywords).

* Logging - log4j marked <optional>

* Fuseki: Allow multiple service per file, shared datasets

* OSGi fixes (Jaroslav Pullmann)

* Consistent support for transactions in DatasetGraphs

* New module jena-cmds

* JSON result type fix: "literal" not "type": "typed-literal"

* Space saving when parsing (FactoryRDF)
   Parsing RDF now saves space by partial interning RDFTerms
   created during a each parser run.

* Improvements to jena-text to include more text query parsers
   (Osma Suominen)

* General maintenance
Thanks to everyone who created JIRA reporting issues.
