Next.js 15.2 update, released on February 26, 2025, focuses on debugging improvements, such as:
- The error overlay has been re-designed to highlight essential error details: messages, relevant code frames, and call stacks. Noise from external libraries is reduced as well.
- The generateMetadata function supports asynchronous operations without delaying initial page rendering or client-side transitions. Initial paints are faster, even when dynamic data fetching is required for metadata generation.
- Turbopack went through considerable improvements, resulting in up to a 57.6% reduction in compile times and a 30% decrease in memory usage during local development.
The update includes some experimental features as well:
- Next.js offers experimental support for React’s View Transitions API, allowing developers to animate transitions between different views and components seamlessly.
- Using the Node.js runtime in Middleware is now possible, which provides more flexibility for server-side operations.
Next.js team teased some upcoming changes, mainly stabilizing use cache as a standalone feature and releasing persistent caching at Vercel for testing.
