A new `0.2.0` version has just been released. Thanks to all the contributors (including Outreachy applicants!), there’s a lot of nice additions including:

- `to_yaml` and `of_yaml` attributes allowing you to add custom encoders and decoders
- a `skip_unknown` flag for ignoring yaml keys so you can partially decode yaml values
- a `default` attribute
- `[@@deriving yaml]` is now an alias to `[@@deriving to_yaml]` and `[@@ deriving of_yaml]` so you can get decoders, encoders or both.

See the documentation in the README: [GitHub - patricoferris/ppx\_deriving\_yaml: OCaml types to Yaml types and back again](https://github.com/patricoferris/ppx_deriving_yaml)
