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.
Vercel’s Build Output API is now generally available. This API allows any framework, including your own custom-built solution, to take advantage of Vercel’s infrastructure building blocks including Routing Middleware, Edge Functions, Incremental Static Regeneration, Image Optimization, and more.
This specification also allows us to introduce two new commands to Vercel CLI:
vercel build: Build a project locally or in your own CI environmentvercel deploy --prebuilt: Deploy a build output directly to Vercel without sending source code through Vercel's build system
