- AWS AppConfig natively incorporates feature flags, client-side evaluations via the AWS AppConfig Agent, and audience split/segment experimentation integrated with Amazon CloudWatch and cloud data warehouses.
- The legacy evidently API, aws evidently CLI, IAM prefix (evidently:*), and Terraform aws_evidently_* resources were retired on October 17, 2025 in favor of appconfig, appconfigdata, and aws_appconfig_* resources.
