## 0.10.x

Breaking changes:

- [#1131](https://github.com/rails-api/active_model_serializers/pull/1131) Remove Serializer#root_name (@beauby)
- [#1138](https://github.com/rails-api/active_model_serializers/pull/1138) Introduce Adapter::Base (@bf4)
  * Adapters now inherit Adapter::Base. 'Adapter' is now a module, no longer a class.
    * using a class as a namespace that you also inherit from is complicated and circular at time i.e.
      buggy (see https://github.com/rails-api/active_model_serializers/pull/1177)
    * The class methods on Adapter aren't necessarily related to the instance methods, they're more
        Adapter functions
    * named `Base` because it's a Rails-ism
    * It helps to isolate and highlight what the Adapter interface actually is
