The Apache Jena development community is pleased to
announce the release of Apache Jena 4.8.0.
In this release:
* The RDF/XML parser has been converted to use the
Jena IRI abstraction IRIx.
https://github.com/apache/jena/issues/1773
See below.
* New keyword in SPARQL : "ADJUST"
https://github.com/apache/jena/issues/1706
ADJUST adjusts the timezone of time and date related datatypes.
It calls one of:
fn:adjust-dateTime-to-timezone
fn:adjust-date-to-timezone
fn:adjust-time-to-timezone
based on argument type.

== RDF/XML reader changes.
* The RDF/XML parser has been converted to use the
Jena IRI abstraction IRIx.
https://github.com/apache/jena/issues/1773
Uses of RDF/XML read through RIOT (RDFDataMgr, RDFParser) and from the
command line "riot" should see no changes except where both WARN and
ERROR were reported, now only the ERROR happens.
Code that directly calls the RDF/XML parser will encounter the behaviour
seen from RIOT. Relative IRIs will not be in the parsed data. IRI errors
are reported as errors.
The original RDF/XML parser is still accessible:
https://jena.apache.org/documentation/io/rdfxml-io.html
From the command line: "riot --set xmlrdf:xmlrdf0=true ..."
This is the first part of a move to convert the RDF/XML parser to be
consistent with the rest of Jena parsing
1. unified IRI treatment of error handling and reporting throughout Jena
2. improve maintainability
3. allow for alternative providers of IRI functionality
