- Redesigned error UI and improved stack traces: A redesigned debugging experience
- Streaming metadata: Async metadata will no longer block page rendering or client-side page transitions
- Turbopack performance improvements: Faster compile times and reduced memory usage
- React View Transitions (experimental): Experimental support for React's new View Transitions API
- Node.js Middleware (experimental): Experimental support for using the Node.js runtime in Middleware
We've added a feature flag to enable the new experimental View Transitions API in React. This new API allows you to animate between different views and components in your application.
We've overhauled the UI and presentation of error messages in Next.js, making them easier to understand. The new design highlights the core details of the error—such as the message, the relevant code frame, and the call stack—while reducing noise from code in libraries or dependencies. This means you can quickly get to the root of what went wrong and start fixing it faster.
Leveraging the newly introduced owner stacks feature in React, we're now able to provide higher fidelity into where your errors are coming from. Next.js will now be able to surface the subcomponent responsible for throwing the error, skipping over intermediary elements that weren't responsible for creating the element that caused the error.
We're also making it easier to customize your indicator preferences without needing to add additional configuration.
