The Apache Jena development community is pleased to
announce the release of Apache Jena 4.4.0.
== New Fuseki UI
The main item in this release is the updated Fuseki UI thanks to work by
Bruno. The UI has been rewritten for improved maintenance and style. We
look forward to evolving this new code base.
== Dependency Updates
Apache log4j is at 2.17.1
Apache Lucene: is updated to 8.10.1 -> 8.11.1
Titanium JSON-LD updated 1.1.0 -> 1.2.0
as well as all other dependences being checked for updates.

== Fuseki war file
The war file for Fuseki is no longer in the apache-jena-fuseki zip
download. Instead, it is available from the downloads page.
https://jena.apache.org/download/
This halves the size of the zip/tar.gz for the standalone server.
The Fuseki war file does not work in Tomcat10 due to the javax->jakarta
switchover. Apache Tomcat provide a converter:

== Fuseki: HTML file upload support
Fuseki: serviceUpload (HTML file upload only service) is no longer added
in a default configuration. Existing configurations are unaffected.
This is not SPARQL GSP.
GSP (POST/PUT) endpoint accepts HTML file uploads as well as the usual
direct POST/PUT with content-type.
== Improved bulk loader
This release includes the version of the TDB2 xloader for very large
datasets.
It has been used to load 16.6B triples (WikiData all) into TDB2 and
loading truthy (6B) on modest hardware. Thanks to Marco, Lorenz and
Øyvind for running Wikidata load trails.
The loader now now has "--threads=" which been reported to give improved
load times (if the server has the hardware!).
== Assembler for GeoSPARQL
This makes it easier to use GeoPSARQL in a plain Fuseki.
