April 2026: Delivered a focused API Shield enhancement in the cloudflare/cloudflare-docs repo that strengthens endpoint governance and security posture. The key achievement is the introduction of a new cf-risk-zombie label to flag inactive endpoints (no traffic for 32 days), enabling proactive deprecation and reduced surface area for potential threats. In addition, a UI/UX improvement was completed by fixing Steps component rendering on the endpoint labels page, enhancing user experience and accuracy of endpoint labeling. The changes are underpinned by a concise changelog update to document zombie endpoint detection, and overall contribute to documentation quality and maintainability.
