Dear Ontop community,
We are pleased to announce the releases of Ontop 5.4.0 and 5.31!
Ontop 5.4.0 introduces a brand-new query unfolder, support for rdfs:subClassOf*, and bottom-up evaluation of EXISTS, along with TDEngine integration and several performance and refactoring improvements.
Ontop 5.3.1 delivers useful new features such as a database init script and Trino’s ST_Distance, while strengthening support for H2, Dremio, and DuckDB.
Both releases significantly improve stability, performance, and compatibility across databases and SPARQL queries.
