+### Changed
+
+- **Animated:** Animated now always flattens `props.style`, which fixes an error that results from `props.style` objects in which `AnimatedNode` instances are shadowed (i.e. flattened to not exist in the resulting `props.style` object).

Christian Falch	40e45f5366	add support for USE_FRAMEWORKS when using prebuilt React Native Core (#52489 ) Summary: When using prebuilts the USE_FRAMEWORKS setting is not really relevant for the React Native code, since there will not be any source code to build frameworks for - and because we already have a framework for the code in React.XCFramework. This commit adds a new command to the React Native podspecs like we did with the ReactNativeDependencies framework. The method is called `add_rncore_dependency` and it does nothing when building from source - but when linking with the React.XCFramework it explicitly adds linking with the framework. In addition there are a few places in the ruby code where we check for the USE_FRAMEWORK value and changes some settings - where needed this commit will add a separate check to ensure we're building from source when making these changes. bypass-github-export-checks ## Changelog: [IOS] [ADDED] - Added support for using USE_FRAMEWORKS with prebuilt React Native Core Pull Request resolved: https://github.com/facebook/react-native/pull/52489 Test Plan: RNTester: - Builds without USE_FRAMEWORKS as before with/without prebuilt - Builds with USE_FRAMEWORKS=dynamic as before with source - and now also with prebuilt code. - Same goes for the static variant.
