Deprecation should be interpreted as a fair warning that the version will
soon be turned off. Developers will actively be encouraged to upgrade their
code at that point. Sunset means that the version is no longer available.
To be notified about upcoming sunsets, join the [Google
Ad Manager API Sunset Announcements](https://groups.google.com/forum/#!forum/dfpapi-sunset-announce) group and adjust your notification settings. Additionally, you can receive alerts if calls are being made to your network with a deprecated API version by enabling the "Deprecated API in use" notification type in the Ad Manager UI.
