3.3.0

RDF4J 3.3.0 is a minor release that is backward compatible with previous RDF4J releases.

Highlights:

  • A new mechanism for providing per-transaction configuration settings is now available in the Repository and SAIL APIs. Currently used by the ShaclSail.
  • The ShaclSail now supports sh:inversePath (limited to single predicates) and sh:hasValue.
  • Custom SPARQL functions now allow inspection of the triplestore state during evaluation.
  • Improved query plan rendering.
  • Utility functions for working with RDF Containers (Alt, Bag, Seq) added.
  • Experimental support for various new SHACL features (DASH and RSX)
  • Elasticsearch, Lucene and Solr upgrades
  • Support for Java 13 and 14
  • Performance improvements and bug fixes

Upgrade notes

This release is binary compatible with previous releases.

RDF4J 3.1.x and 3.2.x implicitly included the jackson-core, jackson-databind and jackson-annotations dependencies when using the rdf4j-rio-api maven artifact. In version 3.3.0, these dependencies are explicitly excluded. Projects relying on this unintended behavior should check if they need to add these jackson dependencies to their build files.
