Summary: The "next" prerelease channel represents what will be published the next time we do a stable release. We publish a new "next" release every day using a timed CI workflow. When we introduced this prerelease channel a few years ago, another name we considered was "canary". But I proposed "next" instead to create a greater distinction between this channel and the "experimental" channel (which is published at the same cadence, but includes extra experimental features), because some other projects use "canary" to refer to releases that are more unstable than how we would use it. The main downside of "next" is someone might mistakenly assume the name refers to Next.js. We were aware of this risk at the time but didn't think it would be an issue in practice. However, colloquially, we've ended up referring to this as the "canary" channel anyway to avoid precisely that confusion. So after further discussion, we've agreed to rename to "canary". This affects the label used in the version string (e.g. `18.3.0-next-a1c2d3e4` becomes `18.3.0-canary-a1c2d3e4`) as well as the npm dist tags used to publish the releases. For now, I've chosen to publish the canaries using both `canary` and `next` dist tags, so that downstream consumers who might depend on `next` have time to adjust. We can remove that later after the change has been communicated. DiffTrain build for commit https://github.com/facebook/react/commit/2c2476834a7c739ca239750b73f74aa1df144a93.

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 12.4 and Android 5.0 (API 21) 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 repo, @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.
