+## Breaking Change: Parsers No Longer Set `Finding.service`
+
+Starting with DefectDojo 2.58.x, parsers no longer set the `service` field directly on findings.
+
+### Why this is a breaking change
+
+Whenever parsers set the `service` field on findings, this breaks `close_old_findings` functionality.
+
+The reason is that import and reimport differ in a way that import uses the `service` field, however reimport does not include a `service` value. The `close_old_findings` feature only closes findings that match the service value provided in the request. As a result, findings with a non-empty parser-populated service value are not closed.
+
+Also, if the application name changes, findings in the reimport report are no longer matched against existing findings.
+
+### Required actions
+
+- If your integrations relied on parser-populated `service` field, update your workflow to pass service explicitly at import/reimport time when needed.
+- Review automation that depends on `close_old_findings` behavior and verify expected closure scope after upgrading.
