5.3.0

RDF4J 5.3.0 is a minor release that fixes 22 issues since 5.2.2. Highlights Query observability is much stronger in 5.3.0. Query explanations now carry richer runtime telemetry (GH-5701), can be requested and cancelled over HTTP, and are exposed in Workbench with text, JSON, and DOT views plus side-by-side comparison support (GH-5713). The new experimental QueryPlanSnapshotCli helps capture and compare plans across benchmark runs (GH-5691). Server deployment is easier. RDF4J now ships a self-contained Spring Boot distribution for Server and Workbench as rdf4j-server-boot (GH-1502), and the Spring components now include a lightweight rdf4j-spring-boot-sparql-web wrapper for SPARQL-only HTTP services.
