In alignment with our SDKs and Tools Maintenance Policy, AWS SDK for JavaScript v2 will enter maintenance mode on September 8, 2024 and reach end-of-support on September 8, 2025.
Existing applications that use AWS SDK for JavaScript v2 will continue to function as intended, unless there is a fundamental change to how an AWS service works. This is uncommon and would be broadly communicated if it happens. Between September 8, 2024 and end-of-support on September 8, 2025, the AWS SDK for JavaScript v2 will only receive critical bug fixes and security updates. The SDK will not be updated to support new AWS services, new service features, or changes to existing services.
