+### Added
+
+* The largest addition to this release is the addition of the `serde_as` de/serialization scheme.

+ No longer is it a problem to add a custom de/serialization adapter is the type is within an `Option` or a `Vec`.
+
+ Thanks to `@markazmierczak` for the design of the trait without whom this wouldn't be possible.
+
+ More details about this new scheme can be found in the also new [user guide](https://docs.rs/serde_with/*/serde_with/guide/index.html)
