hunk.code_window: ---
   Expo provides various settings to configure how your app receives over-the-air (OTA) JavaScript updates. OTA updates allow you to publish a new version of your app JavaScript and assets without building a new version of your standalone app and re-submitting to app stores ([read more about the limitations](../../workflow/publishing/)).
   To perform an over-the-air update of your app, you simply run `expo publish`. If you're using release channels, specify one with `--release-channel <channel-name>` option. Please note that if you wish to update the SDK version which your app is using, you need to rebuild your app with `expo build:*` command and upload the binary file to the appropriate app store ([see the docs here](../../distribution/building-standalone-apps)).
   OTA updates are controlled by the [`updates` settings in app.json](../../workflow/configuration/#updates), which handle the initial app load, and the [Updates SDK module](../../sdk/updates/), which allows you to fetch updates asynchronously from your JS.
