- **BREAKING** (only if migrating from 0.4.2): Using a custom prototype will now
  require using the following method:

  ```elixir
  defmodule MyApp.MySchema do
    use Absinthe.Schema
    use Absinthe.Federation.Schema, prototype_schema: MyApp.MySchemaPrototype
  ```

  instead of

  ```elixir
  defmodule MyApp.MySchema do
    use Absinthe.Schema
    use Absinthe.Federation.Schema, skip_prototype: true
    @prototype_schema MyApp.MySchemaPrototype
  ```

## 0.4.2

  ["extend schema" method](README.md#federation-v2) (drop-in replacement).
- **BREAKING**: Now requires Absinthe v1.7 or above
- **BREAKING**: Now requires Elixir v1.12 or above

## 0.3.2

- Bug Fix: [Handle entity type names with multiple words](https://github.com/DivvyPayHQ/absinthe_federation/pull/68)

## 0.3.1

- [Add `@link` directive for importing directives](https://github.com/DivvyPayHQ/absinthe_federation/pull/62)

  > Previously, `import_sdl` was necessary to import Federation 2 directives.
  > The new `link` macro abstracts this and adds the `@link` directive according
  > to the spec. Please refer to the [README](README.md) for usage details.

## 0.3.0

- **BREAKING**: [Parent type for entities to have properly-cased keys](https://github.com/DivvyPayHQ/absinthe_federation/pull/59)

  > Previously, the entity resolvers had a parent map with atom keys that were
  > camelCased if the field name in the query was camelCased. With this version,
  > the parent type's keys will be converted to internal naming convention of
  > your Absinthe.Adapter, defaulting to snake_cased key names.
  >
  > You may need to update your extended type resolvers to receive parent type
  > maps with snake_cased keys.

- **BREAKING**: [@key directive to convert snake_cased field names to camelCased](https://github.com/DivvyPayHQ/absinthe_federation/pull/60)

  > Previously, the key_fields directive was used with camelCased field names,
  > such as `key_fields("someLongKeyName")`. This translated to
  > `@key(fields: "someLongKeyName")` in the schema. If the directive was added
  > with `key_fields("some_long_key_name")`, it translated to
  > `@key(fields: "some_long_key_name")` in the schema.
  >
  > With this version, adding snake_cased keys with this directive will be
  > converted to the external naming convention of your Absinthe.Adapter,
  > defaulting to camelCased field, such as
  > `key_fields("some_long_key_name")` resulting in
  > `@key(fields: "someLongKeyName")`.
  >
  > - If you were using the key_fields directive with camelCased field names,
  >   they may be refactored later since they will not be modified.
  > - If you were using it with snake_cased field names such as
  >   `key_fields("some_long_key_name")` you may need to make sure this change
  >   does not affect your schema.
