The Next.js 15 Release Candidate (RC) is out now for testing. It lets you try out the latest features before the final release.
Here’s what’s new:
- React Support: Now supports React 19 RC, React Compiler (Experimental), and improves hydration errors.
- Caching Changes: Fetch requests, GET Route Handlers, and client navigations are no longer cached by default.
- Partial Prerendering (Experimental): Introduces a new Layout and Page config option for gradual adoption.
- next/after (Experimental): Offers a new API to run code after a response has finished streaming.
- create-next-app: Gets an updated design and a new flag to enable Turbopack in local development.
- Bundling external packages (Stable): Introduces new config options for App and Pages Router.
To try it out, run this command in your terminal:
npm install next@rc react@rc react-dom@rc
