+## [5.2.1] - 2026-02-25
+
+### Fixed
+
+Add missing `[JsonPropertyName]` attributes to properties in the following derived classes:
+
+- `JsonApiResource<T>.Attributes`
+- `JsonApiRelationship<T>.Data`
+- `JsonApiCollectionRelationship<T>.Data`
+
+### Remarks
+
+This change addresses an oversight in previous versions of the library in which some derived generic class properties were missing the `JsonPropertyName` attribute. This introduced errors in the deserialization and serialization processes:
+
+- Deserialized documents would set the property values for the base class, losing the advantage of the generic type property.
+- Serialized documents would produce a second property without the overriding `JsonPropertyName`, falling back to the active `JsonSerializerOptions` instance (if any).
