Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/52292 Adds a new transform that annotates all exported symbols in our V2 JS API snapshot with a version hash based on the shape of all input types. This intends to be a reliable mechanism to indicate how changes to local types will ultimately affect exported types. **Advantages** (over our alternative type inlining prototype) - More intuitive to developers — in that source type changes are preserved closer to their original source code shapes. - Enables useful Git blaming of individual exported APIs — hash for each export line will change every time a type is affected, and relevant commits can be looked up based on this. - Handles recursive types. - Can be **best-effort** with minimal structural effect over time. We are okay with false positives that over-match input type changes (these are refined later in the stack). - Similar to this, is **lower risk** in terms of requiring future updates that may pollute the diff of the body of the API snapshot structurally. **Example change** Example type change with multiple references: D77378010 {F1979784798} ✅ 8 char hash based on input type shapes printed next to each root-exported identifier ✅ For a source change to the `AccessibilityProps` type, 33 dependent exported types are updated with a new hash Changelog: [Internal] Reviewed By: cipolleschi Differential Revision: D77303917 fbshipit-source-id: 9d43a617697418218eb4951e8e9858d125e222b3

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 15.1 and Android 7.0 (API 24) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repository, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
