Jena 5.4.0 was released 18th July 2025 so Jena 5.6.0 approaches.
https://s.apache.org/jena-5.6.0-issues
At the moment there have are 33 issues closed issues
and 46 PRs which are not dependency updates.
Java25 is out.
(caveat about Ubuntu LTS -- you may have to add a repo
https://documentation.ubuntu.com/ubuntu-for-developers/reference/availability/java/)
== Jena 6
We don't have any more external activity to wait for Jena 6.
When Jena 5.6.0 releases, after a short while for any immediate
problems, we can make a branch for "jena5". "main" becomes Jena 6.0.0
development.
We could see 6.0.0 in January 2026 ... maybe -- an aspiration rather
than a plan.
== Jena 6. Reminder.
* Code deprecations planned for removal at Jena 6.0.0
* Minimum java version: Java 21
* Lucene update to 10.* (this requires Java21+)
* Switch to jena-iri3986 as the IRI parser; retire jena-iri
* Retire jena-permissions

* More deprecation of TDB1 but not for removal at Jena 6.0.0.

Testing of RDF parsing and SPARQL has consolidated on using the
latest rdf-tests. https://github.com/w3c/rdf-tests/
There was a lot of overlap because Jena was using tests from earlier
test collections that now available at rdf-tests.
https://github.com/apache/jena/issues/3453
The tests for major modules have been moved to JUnit5.
