+==== Apache Jena 5.4.0
+Released: 2025-04-27
+Issues: https://s.apache.org/jena-5.4.0-issues
+Announcement:
+https://lists.apache.org/thread/j8qx6zbxgl12d42q3bpckfxjh760jx9m
+
+Jena 5.4.0 introduces a preview of RDF 1.2 support.
+This work is *experimental* and is subject to change
+in future releases.
+
+== RDF 1.2
+
+RDF 1.2 is different to the RDF-star Community Group proposal. This
+release gives users a chance to assess the impact if they use any of the
+RDF-star CG work (i.e. have << >> in the data).
+
+The RDF 1.2 / SPARQL 1.2 specs aren't finished.
+Jena will track the work of the RDF and SPARQL Working Group.
+
+In this experimental release:
+- Triple terms and rdf:reifies.
+- Initial text direction of literals.
+- API updated for RDF 1.2.
+- Turtle, Trig, N-Triples, Q-quads and SPARQL parsing updated for
+ triple terms and initial text direction.
+
+Not in this experimental release:
+- Rendering of SPARQL result sets in the Fuseki UI
+- RDF/XML support
+- Turtle pretty printing. The turtle output is correct RDF 1.2 but
+ there is no Turtle pretty printing using the syntax for reified
+ triples or annotations.
+- HTTP protocol changes
+- There are working group discussions about version directives which
+ are still in-progress within the working group. There is nothing
+ in the experimental Jena code.
+
+The RDF 1.2 Primer:
+https://www.w3.org/TR/rdf12-primer/#section-triple-terms
+
+RDF 1.2 Concepts and Abstract Syntax
+https://www.w3.org/TR/rdf12-concepts/
+
+RDF 1.2 Turtle
+https://www.w3.org/TR/rdf12-turtle/
+
+SPARQL 1.2 Query
+https://www.w3.org/TR/sparql12-query/
+
+These document are currently working group drafts.
+
+== New artifact
+
+Jena 5.4.0 introduces a new module jena-langtag for language tag parsing
+in compliance with RFC 5646. Language tag validation is strengthened.
+When parsing, language tag violations are still treated as warnings.
+
+== Contributions
+
+@Ostrzyciel has contributed several test cases for initialization
+and also cleaning up of Jena's use of Apache Xerces-derived code for RDF
+datatypes:
+
+@OyvindLGjesdal has contributed improvement to the jena-text build for
+java21 and also in fixing the unstable build on github actions.
+
+@Aklakan has contributed support for timeouts in SPARQL Updates,
+provided fixes for closing execution iterators, OpAsQuery, and for
+NodeFmtLib.

==== Apache Jena 5.3.0
Released: 2025-01-21
Issues: https://s.apache.org/jena-5.3.0-issues
Announcement:
https://lists.apache.org/thread/4gk0kpf75hyk58db343hx13nzq8pvldg
-The main feature for Jena 5.2.0 is an implementation of CDT "Composite
-Datatype Literals", an experimental idea for dealing with maps and lists
-in RDF and SPARQL while remaining within RDF 1.1.
+ena 5.3.0 has changes in the structure of the Fuseki server; a new IRI
provider; and clean-up and simplification of Jena's use of Apache Xerces code
in RDF Datatypes.
-All issues in the release:
- https://s.apache.org/jena-5.2.0-issues
+==== Contributions
-and includes
+@Ostrzyciel has contributed several test cases for initialization in
-* hash join improvements
-* performance improvements for RDF/XML parsing, and for command startup.
-* refinement of jena-ontapi

-GH-2578: Fix Quad.isTriple() handling in JenaTitanium
- @Ostrzyciel Piotr Sowiński
+The artifact jena-fuseki-main now has equivalent functionality, including UI,
to the former Fuseki/webapp packaging.
+
+The artifact jena-fuseki-server packages jena-fuseki-main with dependencies
and UI files into a single jar. This is now the jar
+in the Fuseki download.
+
+It should be a drop-in replacement.
+
+There is no functionality added or removed; it is a better base for future
development.
+
+Fuseki/webapp packaging for the WAR file which will continue to be produced
but may not get all future Fuseki development features.
+
+==== IRI3986
+
+Issue: https://github.com/apache/jena/issues/2800
+New maven artifact and jar: jena-iri3986.
+
+This adds a new IRI parser and checker. It is the upcoming replacement for
jena-iri.
+
+General URIs are handled, with additional URI scheme specific rules for:
+ http:, https:, did:, file:,
+ urn:, (including urn:uuid:, urn:oid:),
+ example:
+and non-standard schemes
+ uuid: and oid:
+
+When parsing, "Bad syntax", that is, not passing the grammar of RFC 3986 is
treated as a parse error. Violations of scheme-specific rules are warnings. The
severity levels can be adjusted.
+
+This is the same as principle as Jena has had, but the parser/checker is
+jena-iri3986 supports URI scheme-specific rules for the latest
+
+This new IRI implementation is not active by default.
+
+It is activated by setting the environment variable
+
+ JENA_IRIPROVIDER=IRI3986
+
+or java system property, then call SystemIRIx.reset().
+
+On the command line, try it out with
+
+ env JENA_IRIPROVIDER=IRI3986 riot MyInterestingData.ttl
