# Deprecation notices This page is used to list deprecation notices for ntfy. Deprecated commands and options will be **removed after ~3 months** from the time they were deprecated. ## Active deprecations ### Android app: WebSockets will become the default connection protocol > Active since 2022-03-13, behavior will change in **June 2022** In future versions of the Android app, instant delivery connections and connections to self-hosted servers will be using the WebSockets protocol. This potentially requires [configuration changes in your proxy](https://ntfy.sh/docs/config/#nginxapache2caddy). Due to [reports of varying battery consumption](https://github.com/binwiederhier/ntfy/issues/190) (which entirely seems to depend on the phone), JSON HTTP stream support will not be removed. Instead, I'll just flip the default to WebSocket in June. ### Android app: Using `since=<timestamp>` instead of `since=<id>` > Active since 2022-02-27, behavior will change in **May 2022** 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. ## Previous deprecations ### Running server via `ntfy` (instead of `ntfy serve`) > Deprecated 2021-12-17, behavior changed with v1.10.0 As more commands are added to the `ntfy` CLI tool, using just `ntfy` to run the server is not practical anymore. Please use `ntfy serve` instead. This also applies to Docker images, as they can also execute more than just the server. === "Before" ``` $ ntfy 2021/12/17 08:16:01 Listening on :80/http ``` === "After" ``` $ ntfy serve 2021/12/17 08:16:01 Listening on :80/http ```
