This is an important reminder for those of you who use the AdWords API. On April 22, most v13 services will be turned off. To make sure that your application continues to work after this date, we recommend migrating to v200909 as soon as possible.
If you're an API user, you might want to follow the AdWords API Blog. It's a great place to learn about what's changing with the product and find migration resources.
If you're not an API user, but would like to learn more about it, visit the Google Code website.
