Announcing end-of-support for AWS SDK for Java v1.x effective December 31, 2025

In alignment with our SDKs and Tools Maintenance Policy, the AWS SDK for Java v1.x will enter maintenance mode on July 31, 2024, and reach end-of-support on December 31, 2025.

Existing applications that use AWS SDK for Java v1.x 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 July 31, 2024 and end-of-support on December 31, 2025, the AWS SDK for Java v1.x 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.

The following table outlines the level of support for each phase of the SDK lifecycle.

SDK Lifecycle Phase Start Date End Date Support Level
General Availability March 25, 2010 July 30, 2024 During this phase, the SDK is fully supported. AWS will provide regular SDK releases that include support for new services, API updates for existing services, as well as bug and security fixes.
Maintenance mode July 31, 2024 December 30, 2025 AWS will limit SDK releases to address critical bug fixes and security issues only. The SDK will not receive API updates for new or existing services, or be updated to support new regions.
End-of-support December 31, 2025 N/A The SDK will no longer receive updates or releases. Previously published releases will continue to be available via public package managers and the code will remain on GitHub.

We recommend that you migrate to AWS SDK for Java v2.x. AWS SDK for Java v2 provides improved features, enhanced performance, and continued support from AWS. By adopting the latest version of the SDK, developers can ensure the security, compatibility, and stability of their solutions on AWS. Updating also allows you to leverage the latest services and innovations from AWS. To learn more, refer to the following resources:
