-The [`util.log()`][] API is deprecated.
+The [`util.log()`][] API has been deprecated because it's an unmaintained
+legacy API that was exposed to user land by accident. Instead,
+consider the following alternatives based on your specific needs:
+
+* **Third-Party Logging Libraries**
+
+* **Use `console.log(new Date().toLocaleString(), message)`**
+
+By adopting one of these alternatives, you can transition away from `util.log()`
+and choose a logging strategy that aligns with the specific
+requirements and complexity of your application.
