+- Massively improved the `#[graphql_interface]` macro. ([#682](https://github.com/graphql-rust/juniper/pull/682)):
+  - Applicable to traits and generates enum or trait object to represent a GraphQL interface.
+  - Supports passing context and executor to a field resolver. 
+  - Supports custom downcast functions and methods.
+  - Supports generics.
+  - Supports multiple `#[graphql_interface]` attributes.
 
- - The `GraphQLEnum` derive now supports specifying a custom context. ([#621](https://github.com/graphql-rust/juniper/pull/621))
-   - Example:
-   ```rust
-   #[derive(juniper::GraphQLEnum)]
-   #[graphql(context = CustomContext)]
-   enum TestEnum {
