Vercel announced full support for Next.js 16.3, including immutable static assets, faster routing, and improved observability. Upgraded apps saw 45% fewer prefetch requests, 17% fewer CDN requests, and up to 60% global TTFB reductions. Vercel also launched observability for Partial Prerendering (PPR).

## Evidence

Verbatim from https://vercel.com/blog/vercel-supports-next-js-16-3:

> Applications that have upgraded have seen: Fewer prefetch requests : Apps upgrading from 16.2 to 16.3 saw 45% fewer prefetch requests on average, with some seeing reductions over 70%. Lower static asset costs : With immutable static assets, upgraded apps saw 17% fewer CDN requests and 24% fewer bytes transferred for static content, and up to 60% global TTFB reductions for frequently deployed projects. Faster routing at scale : Routing metadata improvements in the critical serving path deliver ~2x faster p99 route resolution for large sites.
