+## 3.44.2
+**`(fix):`** Generate named Java wrapper classes for unknown type aliases. Previously,
+when an API schema had no `type` and no `properties` (representing an
+"any" type), the generator dropped the named type definition and inlined
+`Object` wherever it was referenced. Unknown type aliases now generate a
+proper wrapper class (e.g. `DocumentedUnknownType`) based on
+`java.lang.Object`, consistent with how other alias types are handled.
