Minor Changes

• #16739 6af492e Thanks @GregBrimble! - Add custom Cloudflare API headers through CLOUDFLARE_API_HEADERS

  Set CLOUDFLARE_API_HEADERS to a JSON object such as {"X-Custom-Header":"value"} to add headers to Cloudflare API requests. Custom headers override existing unprotected request headers, body and transport headers are protected, and header values outside the diagnostic allowlist remain redacted regardless of log sanitization settings.

Patch Changes

• #16810 cdc970b Thanks @dependabot! - Update DEFAULT_COMPAT_DATE to 2026-11-10

  Use the bundled workerd release's compatibility date by default when scaffolding new projects or when no compatibility date is configured.

• #16740 44b39b0 Thanks @GregBrimble! - Redact header values outside a safe diagnostic allowlist, regardless of log sanitization settings.

  Apply the same filtering to request, response, and request-options diagnostics. Strip X-Auth-Key alongside Authorization when forwarding local artifact Git requests.
