 ### Added
 - `no_drop` item-level option to `ZeroizeOnDrop` which does not implement
   `Drop` but instead only asserts that every field implements `ZeroizeOnDrop`.
+- Support deriving Serde's `Deserialize` and `Serialize` trait via Serde's own

 ### Changed
 - Error messages now point to crate features instead of reporting traits as
