In alignment with our previous announcement in August 2025 and SDKs and Tools Maintenance Policy, version 4 of the AWS Tools for PowerShell (AWS Tools for PowerShell v4.x) will enter maintenance mode on March 1, 2026 and reach end-of-support on June 1, 2026.
Beginning March 1, 2026, AWS Tools for PowerShell v4.x will enter maintenance mode and will only receive critical bug fixes and security updates. We will not update it to support new AWS services, new service features, or changes to existing services. Existing applications that use AWS Tools for PowerShell v4.x will continue to function as intended unless there is a fundamental change to how an AWS service works. This is uncommon, and we will announce it broadly if it happens. After June 1, 2026, when AWS Tools for PowerShell v4.x reaches end-of-support, it will no longer receive any updates or releases.
