Please read this if you were an ECS 4 beta tester!

The early ECS 4 beta testers were told to use AWSProductData as the service name.

Later in the beta test we changed this to AWSECommerceService, and we asked everyone to switch as soon as possible, and we warned you that AWSProductData would not be valid forever.

Last year we told you that we would deprecate it really soon.

If you are still using AWSProductData, please switch to AWSECommerceService as soon as possible. We plan to discontinue this non-production feature in the next few weeks.

Thanks!
