 # Changelog
 
+## 1.0.0

+### Breaking Change
+
+- This version adds extra random digits to the URL used by the Twilio Video Apps. The format of the URL has changed from `https://video-app-xxxx-dev.twil.io` to `https://video-app-xxxx-yyyy-dev.twil.io`. The iOS and Android video apps must be upgraded in order to work with this new format. The React app does not need to be upgraded.

 ### Features

This behavior allows users to update an existing deployment's passcode without changing their application's URL. This betterment was proposed in #14.
