Vercel now reuses static files across deployments for frameworks that output content-addressed assets. It's zero-config: Vercel uses Framework-defined infrastructure to manage these immutable files alongside your code changes, handling the hard parts like hash collisions, file lifecycles, and efficient routing.

This brings several benefits:

Lower costs and improved cache hit rates — For frameworks using query-parameter-based Skew Protection (such as Next.js), we saw 17% fewer CDN requests and 24% fewer bytes transferred for static content.

Faster Deployments — Deployments complete up to 30% faster on average.

Faster Time to First Byte — Immutable assets can remain cached across deployments, giving frequently deployed projects up to a 60% reduction in global TTFB.

Vercel's supported frameworks will automatically take advantage of this optimization, even for projects without Skew Protection enabled.…
