RDF4J 5.3.0 Milestone 2

Milestone number 2 of the upcoming 5.3.0 release of RDF4J is now available for download.

RDF4J 5.3.0 is a minor release focusing on stability and getting the code ready for the next major release.

Notable changes in 5.3.0 M2

• SHACL validation can now be configured more precisely for inferred data (GH-5676). If a shape (or global SHACL setting) disables inferred statements, underlying sails must emit inferred-aware callbacks by implementing statementAdded(Statement, boolean inferred) and statementRemoved(Statement, boolean inferred) in SailConnectionListener.
• Query builder fix: FILTER NOT EXISTS is now preserved when adding GraphPatterns.filterNotExists(...) to an empty GraphPatterns.and() (GH-5561).
• Parser extension note: if you subclass TupleExprBuilder and override createAnonVar(), consider also overriding newer specialized methods used during parsing: createAnonCollectionVar(), createAnonBnodeVar(), createAnonHavingVar(), and createAnonPathVar(boolean).
• Var remains extensible through SPI (as introduced in M1): use Var.of(...) factories, provide a custom Var.Provider (newVar(...) and optionally cloneVar(...)), and register via META-INF/services/org.eclipse.rdf4j.query.algebra.Var$Provider or the org.eclipse.rdf4j.query.algebra.Var.provider system property.
• Additional end-user fixes include support for refining JSON-LD @context (GH-5573) and major LuceneSail transaction performance improvements (GH-5291).

Deprecations since 5.2.0

• Legacy compare methods in org.eclipse.rdf4j.query.algebra.evaluation.util.QueryEvaluationUtil:
  • compare(Value, Value, CompareOp)
  • compare(Value, Value, CompareOp, boolean)
  • compareLiterals(Literal, Literal, CompareOp)
  • compareLiterals(Literal, Literal, CompareOp, boolean)
• Constructors in org.eclipse.rdf4j.query.algebra.Var are now deprecated (for removal), use Var.of(...) factories instead:
  • Var(String, Value, boolean, boolean)
  • Var(String)
  • Var(String, boolean)
  • Var(String, Value)
  • Var(String, Value, boolean)
• Elasticsearch integration APIs deprecated for removal (preparation for Elasticsearch client upgrade):
  • org.eclipse.rdf4j.sail.elasticsearchstore.ElasticsearchStore
  • org.eclipse.rdf4j.sail.elasticsearchstore.ElasticsearchStoreConnection
  • org.eclipse.rdf4j.sail.elasticsearchstore.SingletonClientProvider
  • org.eclipse.rdf4j.sail.elasticsearchstore.UserProvidedClientProvider
  • org.eclipse.rdf4j.sail.elasticsearchstore.config.ElasticsearchStoreConfig
  • org.eclipse.rdf4j.sail.elasticsearchstore.config.ElasticsearchStoreFactory
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchBulkUpdater
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocument
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentDistance
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentResult
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentScore
  • org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchIndex
  • org.eclipse.rdf4j.sail.elasticsearch.config.ElasticsearchSailConfig
  • org.eclipse.rdf4j.sail.elasticsearch.config.ElasticsearchSailFactory
• Solr integration APIs deprecated for removal:
  • org.eclipse.rdf4j.sail.solr.SolrBulkUpdater
  • org.eclipse.rdf4j.sail.solr.SolrClientFactory
  • org.eclipse.rdf4j.sail.solr.SolrDocumentDistance
  • org.eclipse.rdf4j.sail.solr.SolrDocumentResult
  • org.eclipse.rdf4j.sail.solr.SolrDocumentScore
  • org.eclipse.rdf4j.sail.solr.SolrIndex
  • org.eclipse.rdf4j.sail.solr.SolrSearchDocument
  • org.eclipse.rdf4j.sail.solr.SolrSearchQuery
  • org.eclipse.rdf4j.sail.solr.SolrUtil
  • org.eclipse.rdf4j.sail.solr.client.cloud.Factory
  • org.eclipse.rdf4j.sail.solr.client.embedded.Factory
  • org.eclipse.rdf4j.sail.solr.client.http.Factory
  • org.eclipse.rdf4j.sail.solr.config.SolrSailConfig
  • org.eclipse.rdf4j.sail.solr.config.SolrSailFactory

This milestone build is not yet feature-complete, but we are putting it out to receive early feedback on all the improvements we have put in.
