+### Android app: Using `since=<timestamp>` instead of `since=<id>` 
+> since 2022-02-27
+
+In about 3 months, the Android app will start using `since=<id>` instead of `since=<timestamp>`, which means that it will
+not work with servers older than v1.16.0 anymore. This is to simplify handling of deduplication in the Android app.
+
+The `since=<timestamp>` endpoint will continue to work. This is merely a notice that the Android app behavior will change.

+Depending on whether the server is configured to support [access control](../config.md#access-control), some topics
+may be read/write protected so that only users with the correct credentials can subscribe or publish to them.
+To publish/subscribe to protected topics, you can use [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication)
+with a valid username/password. For your self-hosted server, **be sure to use HTTPS to avoid eavesdropping** and exposing
+your password. 
+
+You can either add your username and password to the configuration file:
+=== "~/.config/ntfy/client.yml"
+	```yaml
+	 - topic: secret
+	   command: 'notify-send "$m"'
+	   user: phill
