Note: This changelog entry is historical. Edge Functions are deprecated for new projects. Use Vercel Functions with the Node.js runtime and Fluid compute. Use Routing Middleware for request-time routing before a response completes.
Edge Functions are now available in Public Beta. They allow developers to deliver content to your site with speed and personalization, by enabling them to serve the exact end-user experience they're imagining, every time. Edge Functions have instant cold boots, support streaming, and are deployed globally by default.
For current projects, use Vercel Functions with the Node.js runtime and Fluid compute. Use Routing Middleware for request-time routing before a response completes.
