+## Announcement 📣
+
+There is a standard approach to recursion and more data-types than what JSON allow, and it's part of this [Structured Clone Module](https://github.com/ungap/structured-clone/#readme).
+
+Beside acting as a polyfill, its `@ungap/structured-clone/json` export provides both `stringify` and `parse`, and it's been tested for being faster than *flatted*, but its produced output is also smaller than *flatted*.
+
+The *@ungap/structured-clone* module is, in short, a drop in replacement for *flatted*, but it's not compatible with *flatted* specialized syntax.
+
+However, if recursion, as well as more data-types, are what you are after, or interesting for your projects, consider switching to this new module whenever you can 👍
