AWS CDK is splitting Construct Library and CLI

Open Source Blog



AWS is changing how the AWS Cloud Development Kit (CDK) manages its Construct Library and CLI versioning:

  • Starting February 2025, CDK CLI and Construct Library will have independent release cycles
  • Version numbers will no longer be synchronized
  • CLI will start at version 2.1000.0, while Construct Library continues its current version line
  • The major version will remain at 2.x to maintain automatic dependency updates
  • CLI source code will move to a new GitHub repository: aws/aws-cdk-cli

Key recommendations for users:

  • Keep CLI at the latest version
  • Use Construct Library version as the primary CDK version
  • Update scripts that assume a single version number

The change aims to provide more agility in development and faster improvements to the CDK framework.
