-- **Error Handling:** Unhandled promises are now handled by ExceptionsManager.handleException, instead of being swallowed as Logbox Warnings. ([c4082c9ce2](https://github.com/facebook/react-native/commit/c4082c9ce208a324c2d011823ca2ba432411aafc) by [@krystofwoldrich](https://github.com/krystofwoldrich))
-- **InteractionManager:** InteractionManager has been deprecated and no longer respects interaction handles. Instead, it is now recommended to avoid executing long-running JavaScript tasks by breaking them up into smaller tasks and scheduling them using `requestIdleCallback()`. ([03d9f34a82](https://github.com/facebook/react-native/commit/03d9f34a8252456d389d9f9a3bd04b99a2828c16) by [@yungsters](https://github.com/yungsters))

-- **ViewManagerInterfaces:** Migrate ViewManagerInterfaces to kotlin. Some types in code generated ViewManagerInterfaces might differ. e.g. this will start enforcing nullability in parameters of viewManagerInterface methods (e.g. String commands parameters are not nullable, view params are not nullable in any method, etc) ([79ca9036d3](https://github.com/facebook/react-native/commit/79ca9036d39c16cd115dc0427cb7092f358ac47e) by [@mdvacca](https://github.com/mdvacca))

-## Experimental features
-
-React Native frameworks may pass an `unstable_experiments` option to `createDevMiddleware` to configure experimental features. Note that these features might not work correctly, and they may change or be removed in the future without notice. Some of the experiment flags available are documented below.
-
-### `unstable_experiments.enableStandaloneFuseboxShell`
-
-When `true`, the debugger frontend will launch in a standalone app shell (provided by the `@react-native/debugger-shell` package) rather than in a browser window. The standalone shell provides an improved experience and will become the default in a future version of React Native.
-
-The shell is powered by a separate binary that is downloaded and cached in the background (immediately after the call to `createDevMiddleware`). If there is a problem downloading or invoking this binary for the first time, the debugger frontend will revert to launching in a browser window until the next time `createDevMiddleware` is called (typically, on the next dev server start).
-

 Changes to this package can be made locally and tested against the `rn-tester` app, per the [Contributing guide](https://reactnative.dev/contributing/overview#contributing-code). During development, this package is automatically run from source with no build step.
