 To prevent the accidental exposure of applications, we've updated how Worker [preview URLs](/workers/configuration/previews/) (<PREVIEW>-<WORKER_NAME>.<SUBDOMAIN>.workers.dev) are handled. We made this change to ensure preview URLs are only active when intentionally configured, improving the default security posture of your Workers. 
 
 **What has changed:**
-- New Default Behavior: If a Worker's [`workers.dev`](/workers/configuration/routing/workers-dev/) route is disabled and its preview URL is not explicitly configured, the preview URL will now default to disabled. However, you can still explicitly enable the preview URL regardless of your `workers.dev` enablement status by doing `preview_urls = true`
+- New Default Behavior: If a Worker's [`workers.dev`](/workers/configuration/routing/workers-dev/) route is disabled and its preview URL is not explicitly configured, the preview URL will now default to disabled. However, you can still explicitly enable the preview URL regardless of your `workers.dev` enablement status by configuring it in the dashboard, or by setting `preview_urls = true` in your Wrangler configuration file.
 - One-Time Update for Existing Workers: We performed a one-time update to disable preview URLs on existing Workers with a disabled `workers.dev` route. This ensures an explicit opt-in is required going forward.
 - Re-enabling Preview URLs: If your preview URL was disabled, you can re-enable it through the Worker's settings page in the dashboard or by updating the Worker's configuration file and deploying with Wrangler (minimum of version 4.34.0).
