AI Changelog

New Features

Flight: Experience improved error handling during JSON stringify of console values, ensuring that serialization does not fail even with complex data structures. Enjoy enhanced support for Async Modules in Server References, allowing for better integration with top-level await in server modules. Benefit from the new renderToMarkup function, which allows for rendering components to HTML in a non-RSC environment, enhancing flexibility in rendering.
DevTools: Experience improved error tracking with the addition of owner stacks, providing better context for errors thrown in Server Components. Enjoy the new feature that allows you to jump to the definition of functions directly from the DevTools, making debugging more intuitive.
Compiler: Introduce support for useTransition, allowing for smoother state transitions in your applications. This built-in hook returns a stable value, similar to useState, enhancing the user experience during updates.

Improvements

Flight: Experience non-blocking prerendering, allowing for smoother transitions and improved performance during data fetching.
DevTools: Benefit from improved console argument formatting, ensuring that logs are clearer and more informative when debugging. Enjoy enhanced performance tracking with the new ability to log component renders, providing deeper insights into rendering performance. Experience a more responsive UI with optimizations that reduce delays in element inspection and interaction.
Compiler: Enhance the handling of refs, allowing for more flexible usage in hooks and components, which improves the overall developer experience.
React DevTools: Improve the context menu functionality to work seamlessly in various environments, enhancing usability for developers.

Fixes

Fix issues with console.error and console.warn not displaying the correct component stack, ensuring that all relevant context is available during debugging. Fix a bug where certain errors in React Native would not display the correct stack trace, improving error visibility for developers. Fix the handling of errors during JSON serialization in Flight, ensuring that errors do not cause the application to crash.
Fix issues with useMemoCache resetting on setState calls during render, preventing infinite loops and ensuring stable performance. Fix the validation logic for React.Children to ensure that keys are properly checked, preventing warnings for valid cases.

Others

Enhance the documentation for the prerender API in the React Server Components package, providing clearer guidance for implementers. Introduce a new README for the react-server package, offering essential information to help developers get started with React Server Components.
Update the README to include a hyperlink to Node.js, making it easier for beginners to find relevant resources.
