  - 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](https://github.com/eclipse-rdf4j/rdf4j/issues/5573)) and major LuceneSail transaction performance improvements ([GH-5291](https://github.com/eclipse-rdf4j/rdf4j/issues/5291)).
+ - Inclusion of two new SPARQL result set formats: directly generating spreadsheets for ODF (LibreOffice etc) and OOXML (Microsoft Office) ([GH-5290](https://github.com/eclipse-rdf4j/rdf4j/issues/5290)). This includes new dependencies for the OOXML format.
