| ## [5.0.0] | ||
| ### Added | ||
| - Add types `ComposableControllerState`, `ComposableControllerStateChangeEvent`, `ComposableControllerEvents`, `ComposableControllerMessenger` ([#3590](https://github.com/MetaMask/core/pull/3590)) | ||
| ### Changed | ||
| - **BREAKING:** `ComposableController` is upgraded to extend `BaseControllerV2` ([#3590](https://github.com/MetaMask/core/pull/3590)) | ||
| - The constructor now expects an options object with required properties `controllers` and `messenger` as its only argument. | ||
| - `ComposableController` no longer has a `subscribe` method. Instead, listeners for `ComposableController` events must be registered to the controller messenger that generated the restricted messenger assigned to the instance's `messagingSystem` class field. | ||
| - Any getters for `ComposableController` state that access the internal class field directly should be refactored to instead use listeners that are subscribed to `ComposableControllerStateChangeEvent`. | ||
| - Bump `@metamask/base-controller` to `^4.0.1` ([#3695](https://github.com/MetaMask/core/pull/3695)) | ||
