Enhanced geolocation information for Vercel Functions

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.

Requests received by Vercel Functions are now enriched with headers containing information about the timezone of the visitor:

As an example, a request from Tokyo is now enriched with the following headers:

1
X-Vercel-IP-Latitude: 37.7749
2
X-Vercel-IP-Longitude: -122.4194

3
X-Vercel-IP-Timezone: Japan

This header is now automatically activated for all new and existing Vercel Functions for all plans — no code or configuration change needed.
