+.. note:: Motor Deprecation
+
+   As of May 14, 2025, Motor is deprecated in favor of the GA release of the PyMongo Async
+   API in the PyMongo library. We will not add new features to Motor, and we will
+   provide only bug fixes until it reaches end of life on May 14, 2026. After that, we will
+   fix only critical bugs until final support ends on May 14, 2027. We
+   strongly recommend migrating to the PyMongo Async API while Motor is still supported.
+    
+   For more information about migrating, see the `Migrate to PyMongo Async <https://www.mongodb.com/docs/languages/python/pymongo-driver/current/reference/migration/>`__
+   guide in the PyMongo documentation.
