== About Apache Jena

Apache Jena is a Java framework for building Semantic Web applications. 
Jena provides a collection of tools and Java libraries to help you to 
develop semantic web and linked-data applications, tools and services.

== Notable changes

* RDF Output

The writer for Turtle which has been rewritten and a writer for TriG 
added.  The exact output layout of the Turtle may change.

Full details of using the writing subsystem:
   http://jena.apache.org/documentation/io/rdf-output.html

* RETE patch for faster forward rule execution
   (contribution from Tilo Fischer)

* Improved Fuseki service startup script
   (contribution from Luís Duarte)

* Improve ParameterizedSparqlString to prevent SPARQL injection attacks.

* Query timeouts (including in Fuseki)

Timeouts now happen at the right point. The Fuseki status code from a 
timeouts query was incorrectly 408 - it's now 503.

* New optimizations for ORDER BY + DISTINCT/REDUCED combinations that 
gives substantially better performance for some queries

* Improvements to statistics calculations in TDB to handle rdf:type.
Large databases, with small numbers of different classes, may benefit
from recalculating stats.opt.
