The AWS Cloud Development Kit (AWS CDK) v2 for JavaScript, TypeScript, Java, Python, .NET and Go (preview) is now generally available in a single package, making it easier for you to use the CDK and stay up-to-date with new versions as we evolve it going forwards. AWS CDK v2 consolidates the AWS Construct Library into a single package called aws-cdk-lib, and eliminates the need to download individual packages for each AWS service used. If you write your own CDK construct libraries, you only need to take a minimum dependency on this single package and let library consumers choose which exact AWS CDK version to use.
