+We are announcing the deprecation and removal of embed API v2.
+Our old API has been replaced by [embed API v3](https://docs.readthedocs.io/en/stable/api/v3.html#embed),
+which offers the same features, and it works for all types of projects, not just Sphinx.
+
+If you are using our [sphinx-hoverxref](https://sphinx-hoverxref.readthedocs.io/en/stable/) extension,
+please update to the latest version to keep the extension working.
+
