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:
X-Vercel-IP-Latitude: 37.7749X-Vercel-IP-Longitude: -122.4194
X-Vercel-IP-Timezone: JapanThis header is now automatically activated for all new and existing Vercel Functions for all plans — no code or configuration change needed.
