react changelog

Hey there, fellow React enthusiasts! 🎉 We've got some exciting updates and fixes coming your way. From improvements in rendering and bundling to new features for React Native, here's a rundown of what's new and improved in our latest update. Let's dive in!

• New Feature: React Native Document Instances 📝 We've added support for Document instances in React Native, known as ReactNativeDocument instances. This change enhances the React Fabric renderer to manage these instances, making it easier for React Native to access them using container or root tags. It's a step forward in integrating document instances within the React Native framework.

• Improvement: Suspense Boundaries in Fiber 🚀 Suspense boundaries can now be rendered at any level within a react-dom application, thanks to an update to Fiber. This enhancement treats the document body as the default render scope, offering more flexibility in rendering Suspense components. Note that hydration isn't supported yet, so Fizz and Fiber aren't fully unified just yet.

• Improvement: Import Maps in React Flight Parcel 📦 We've enhanced the React Flight Parcel bundler by enabling import maps to be passed through client references. This update addresses the limitations of native import maps in client-side navigation scenarios, improving caching strategies and optimizing the performance of React applications using Parcel.

• Improvement: Parallel DevTools Builds ⚙️ Our CI process just got a speed boost! We've parallelized the build process for React DevTools, reducing the CI job runtime. By building DevTools simultaneously for Chrome, Firefox, and Edge, we're streamlining development and getting faster feedback cycles.

• Bugfix: React Compiler Healthcheck Script 🐞 We've fixed an issue with the react-compiler-healthcheck script by adding a shebang. This resolves execution problems with npx, allowing the script to run smoothly and compile components without a hitch.

• Bugfix: Removal of Unused Rust Port 🛠️ We've cleaned up by removing an unused experimental Rust port of the React Compiler. While the experiment showed promise, we're sticking with JavaScript for the React Compiler, focusing on lightweight native wrappers and collaboration with the Hermes team.

• Chore: Maintainers Update 🔧 Our MAINTAINERS file got a refresh! We've added a new maintainer, "unstubbable," and removed some old entries. This update keeps our contributor list accurate and up-to-date.

• Bugfix: Typo Correction in CI ✏️ A small typo in the GitHub Actions workflow file has been fixed, ensuring error messages are clear and correctly formatted.

We hope these updates make your React experience even better! Keep building, and stay tuned for more improvements. Happy coding! 🌟
