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
