 # Adding a New Data Source
 
 New data sources are required when AWS adds a new service, or adds new features within an existing service which would require a new data source to allow practitioners to query existing resources of that type for use in their configurations. Anything with a Describe or Get endpoint could make a data source, but some are more useful than others.

 ## Which SDK Version should I use?
 
-Each Terraform provider implementation for an AWS service relies on a service client which in turn is constructed based on a specific SDK version.
-At present, we are slowly increasing our footprint on SDK v2, but are not actively migrating existing code to use v2.
-The choice of SDK will be as follows:
+At this time **all net-new services are required to use AWS Go SDK v2**.
+Enhancements or bug fixes to existing AWS Go SDK v1 based services do not require migration.
+You can determine the SDK version a given service uses by looking at the `import` section in the service's Go files.
+Where applicable, the contributor guide has been updated to include examples with both AWS Go SDK v1 and v2.
 
-For new services, you should use [AWS SDK for Go v2](https://github.com/aws/aws-sdk-go-v2).
+We are beginning to migrate core services written with v1 onto v2, and adoption will continue to increase over time.
 AWS has a [migration guide](https://aws.github.io/aws-sdk-go-v2/docs/migrating/) that details the differences between the versions of the SDK.
 
-For existing services, use the version of the SDK that service currently uses.
-You can determine this by looking at the `import` section in the service's Go files.
-
 ## What does the SDK handle?
 
 The AWS SDKs handle calling the various web service interfaces for AWS services.
