Releasesby IbisWorkers, BYOIP, Bots - Workers subrequests now preserve context for BYOIP destinations
UpdateyesterdayUnverifiedAdded Oct 14, 2026
Cloudflare now preserves Workers context when a subrequest targets a Cloudflare-proxied hostname using Bring Your Own IP (BYOIP) . These requests are identified as Cloudflare-to-Cloudflare traffic instead of external Internet traffic. Previously, some BYOIP subrequests could lose Workers context and original client signals.
More Cloudflare developer platform releases
Every Cloudflare developer platform releaseAgents, Workers - Cloudflare API MCP server sends Workers Issues as MCP Events
Workers Issues provides built-in error monitoring for Cloudflare Workers. It detects production failures and groups related failures into issues without an SDK or application wrapper. The Cloudflare API MCP server now sends these issues as MCP Events ↗︎ , the first event it exposes.
Agents - New persistent browser tool in the Agents SDK, with tabs and logins that last between turns
The Cloudflare Agents SDK now provides a browserTool that gives your agent a Browser Run browser it can return to on later turns. Your agent can open a website, inspect a page, and come back to it with its tabs, cookies, and login session intact while the browser session remains alive.
Gateway, Cloudflare One - Request Gateway DNS64 through DNS locations and EDNS
You can now request DNS64 through Cloudflare Gateway DNS location settings or Extension Mechanisms for DNS (EDNS) options. DNS64 synthesizes AAAA records from A records for IPv6-only networks. These networks require network address translation from IPv6 to IPv4 (NAT64).
Cloudflare Web Analytics - Deeper Core Web Vitals Diagnostics: LCP & INP Sub-Part Metrics in Real User Monitoring
The Core Web Vitals tell you whether a page is slow but beyond perceived load time, layout instability, or responsiveness they do not guide you to the problematic area directly. To help you with this, Real User Monitoring (RUM) in Web Analytics now breaks Largest Contentful Paint (LCP) and Interaction to Next Paint (INP) into their respective sub-parts.
