-  - Keeps a copy of `value` associated with the WebSocket to survive hibernation. The value can be any type supported by the [structured clone algorithm](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm), which is true of most types. If the value needs to be durable please use [Durable Object Storage](/durable-objects/api/sqlite-storage-api/).
+  - Keeps a copy of `value` associated with the WebSocket connection. Serialized attachments are available as long as their attached WebSocket connection is healthy, even after hibernation. If any side of the connection is closed, the attachments will be lost.
 
-  - If you modify `value` after calling this method, those changes will not be retained unless you call this method again. The serialized size of `value` is limited to 2,048 bytes, otherwise this method will throw an error. If you need larger values to survive hibernation, use the [Storage API](/durable-objects/api/sqlite-storage-api/) and pass the corresponding key to this method so it can be retrieved later.
