 ### Changed
 
+- **BREAKING:** `AbstractMessageManager` now expects a `Name extends string` generic parameter to define the name of the message manager ([#6469](https://github.com/MetaMask/core/pull/6469))
+  - The type is used as namespace for `BaseController` and `Messenger` events and actions.
 - Bump `@metamask/base-controller` from `^8.0.1` to `^8.3.0` ([#6284](https://github.com/MetaMask/core/pull/6284), [#6355](https://github.com/MetaMask/core/pull/6355), [#6465](https://github.com/MetaMask/core/pull/6465))
 - Bump `@metamask/controller-utils` from `^11.11.0` to `^11.12.0` ([#6303](https://github.com/MetaMask/core/pull/6303))
