### New Animation Backend

React Native 0.85 introduces the new Shared Animation Backend, built in collaboration with [Software Mansion](https://swmansion.com/). This is a new internal engine that powers how animations are applied under the hood for both Animated and Reanimated. By moving the main animation update logic to React Native core, Reanimated is able to land performance improvements that weren't possible before, and can ensure that the update reconciliation process is properly tested and will remain stable with future RN updates. In Animated, you can now animate layout props with native driver (the [limitation once stated here](/docs/animations#caveats) no longer applies).

You can find more examples under [`react-native/packages/rn-tester/js/examples/AnimationBackend/`](https://github.com/facebook/react-native/tree/main/packages/rn-tester/js/examples/AnimationBackend).

To opt in, enable `useSharedAnimatedBackend` and `cxxNativeAnimatedEnabled` in `ReactNativeFeatureFlags`.
To opt in, you can enable the experimental channel of React Native [as described in this page](/docs/releases/release-levels).

:::info

This experimental feature will only be available starting from React Native **0.85.1**, which will be released in the immediate future.

#### General

- Removed deprecated TypeScript type aliases — use the types directly.
- `Pressable` no longer unmounts event listeners in hidden `Activity`.
- Removed deprecated C++ type aliases for `ShadowNode::Shared`, `ShadowNode::Weak`, `ShadowNode::Unshared`, `ShadowNode::ListOfWeak`, `ShadowNode::ListOfShared`, `SharedImageManager` and `ContextContainer::Shared` — Those were not in use and consumer libraries should use the type directly.

- Deprecated `UIManagerHelper` methods and classes.
- Removed `CatalystInstanceImpl` and other legacy architecture classes.
- Stubbed out `NativeViewHierarchyManager`.
- We re-added `receiveTouches` to `RCTEventEmitter` with default no-op. This is a fix to reduce breaking changes for libraries that haven't migrated away from this method yet.

- Multiple classes deprecated or removed as legacy architecture cleanup:
- `ReactZIndexedViewGroup` is now deprecated.
- `UIManagerHelper` is now deprecated.
