 In case your Webxdc was just started,
 you may want to reconstruct the state from the last run -
 and also incorporate updates that may have arrived while the app was not running.

+The updates are wrapped into a Promise that you can `await` for.
+If you are not in an async function and cannot use `await` therefore,
+you can get the updates with `then()`:
 
 ```js
-addr = window.webxdc.selfAddr()
+window.webxdc.getAllUpdates().then(updates => {});
 ```
 
-Returns the peer's own address.

 This is esp. useful if you want to differ between different peers -
 just send the address along with the payload,
 and, if needed, compare the payload addresses against selfAddr() later on.
