• Fix an issue with generating static metamodel under JDK 21 (Bug #257).
• Support using URI/URL as data property values (as RDF simple literal) (Enhancement #256).
• Support target ontology query hint (Enhancement #245).
• Dependency updates: Jena 5.1.0, RDF4J 5.0.1.

• Fix a NPX when calling EntityManager.isInferred with lazy loading proxy (Bug #252).
• Allow using multiple values for a query parameter that is written into SPARQL VALUES clause (Bug #246).
• Dependency updates: RDF4J 5.0.0.
  • Update note: Still compatible with server 4 and, with the right configuration,
    also 3. However, if you are passing repository configuration file to JOPA, make sure it uses the new configuration vocabulary.

• Proper implementation of EntityManager.getReference after 2.0.0 rewrite (Enhancement #233).
• Log JOPA version and build date on persistence unit startup (Enhancement #243).
• Prevent AssertionError on EntityManager.flush calls (Bug #240).
• Fix incorrect SOQL to SPARQL translation when traversing reference and using identifier (Bug #234).
• Fix issues with interaction of lazy loading with cascading (Bug #248).
• Dependency updates: RDF4J 4.3.12.

This is a big release containing potentially breaking changes.

In summary: AspectJ is no longer needed to build projects using JOPA. Java 17 is the minimum required Java version.

Changes:

• Rewrote change tracking and lazy loading to not require AspectJ and use generated proxy classes and change calculation on commit (Enhancement #145, #231). See the wiki for details. This should significantly simplify adoption of JOPA in projects.
• Added support for RDF collections (Enhancement #51).

(Potentially) Breaking changes:

• Modified generation of classes and constants in OWL2Java, using ontology prefixes to disambiguate terms with the same label (Enhancement #85).
• Internal APIs were moved from jopa-api to jopa-impl, so that they can be changed without bumping version major (Enhancement #146).
• Java 17 is now minimum Java version (Task #147).
• Updated to Jena 5.0.0, RDF4J 4.3.11.
• Removals of deprecated APIs.
• EntityManager and EntityManagerFactory are now AutoCloseable (in alignment with JPA).

• Modify DefaultClasspathScanner to handle Spring Boot nested JAR introduced in 3.2.0 (Bug #227).

• Unwrap IndirectMultilingualString instances when owner entity is detached from the persistence context.

• Support data properties for referenced list values (Enhancement #209).
• Support using multilingual string as referenced list values (Enhancement #216).
• Fix inconsistent license information (GH #214).
• Dependency updates: Jena 4.10.0, RDF4J 4.3.8.

• Support ignoring removals of inferred values on entity merge into persistence context (Enhancement #189).
• Dependency updates: RDF4J 4.3.7.

• Fix a transaction isolation issue. Now when multiple transactions edit the same data, the one that commits last wins (same behavior as JPA, Bug #202).
• Fix an issue with missing interpretation of prefixes in the @Sequence annotation values (Bug #204).

• Fix missing processing of connection pool configuration in RDF4J driver.
• Disambiguate classes of the same name in OWL2Java using a default suffix (Bug #199).
• Modify JOPA Maven plugin parameter mapping so that it does not confuse IDEs (GH #198).
• Provide access to entity class namespace detection (Enhancement #196).
• Dependency updates: RDf4J 4.3.6.
