+## 5.44.8
+**`(fix):`** Fix example generation for nested allOf $ref chains. When a schema uses
+multi-level allOf (e.g. UserPost → UserBase → UserStrict), properties from
+grandparent schemas were missing from generated code snippets because
+mergeAllOfProperties only resolved one level of allOf. Now recursively
+resolves the full chain so all required fields appear in examples.
