RDF4J 5.3.0 is now available. This minor release resolves 22 issues between 5.2.2 and 5.3.0 and focuses on better query observability, easier deployment, and targeted performance work across the stack.

Highlights include richer EXPLAIN support with runtime telemetry and Workbench compare mode, a new standalone rdf4j-server-boot distribution for Server and Workbench, faster LMDB/Lucene/DISTINCT-heavy workloads, direct .xlsx and .ods SPARQL result export, and several developer-facing additions such as the experimental query renderer and a fluent ShaclValidator API.
