+# [0.2.0](https://github.com/socketio/socket.io-mongo-adapter/compare/0.1.0...0.2.0) (2022-04-27)
+
+
+### Features
+
+* add an option to use a TTL index ([#4](https://github.com/socketio/socket.io-mongo-adapter/issues/4)) ([7fdbb25](https://github.com/socketio/socket.io-mongo-adapter/commit/7fdbb25831255e5f6a37a5df25b4fc41c770ab6a))
+
+The `addCreatedAtField` option allows to use a TTL index instead of a capped collection, which is slightly less efficient but more predictable.
+
+* broadcast and expect multiple acks ([e87a0ce](https://github.com/socketio/socket.io-mongo-adapter/commit/e87a0cec4c6920b5e4ef38c4de3e45c1eba5e4cf))
+
+This feature was added in `socket.io@4.5.0`:
+
+```js
+io.timeout(1000).emit("some-event", (err, responses) => {
+  // ...
+});
+```
+
+Thanks to this change, it will now work with multiple Socket.IO servers.
+
+* use a single stream for all namespaces ([9b5f4c8](https://github.com/socketio/socket.io-mongo-adapter/commit/9b5f4c83038cc212b898b7fb7ff0ccec3124447c))
+
+The adapter will now create one single MongoDB stream for all namespaces, instead of one per namespace, which could lead to performance issues.
