Version 1 of the Amazon Cloud Development Kit ( Amazon CDK) is now in maintenance mode

{"value":"#### **The [AWS Cloud Development Kit](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) ([AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail)) version 1 (v1) for JavaScript, TypeScript, Java, Python, .NET and Go is now in maintenance mode.**\n[AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) v1 is no longer receiving higher-level “L2” construct updates for new or existing services. It will continue receiving updates for new and updated resource level “L1” constructs, critical bug fixes, and security updates only. We recommend you upgrade your applications to the new major version of CDK – [AWS CDK version 2 (v2)](https://docs.aws.amazon.com/cdk/v2/guide/getting_started.html), which continues receiving new features and bug fixes.\n\n#### **On June 1, 2023, [AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) version 1 will reach the end-of-support.**\nAfter that, the [AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) v1 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](https://github.com/aws/aws-cdk/tree/v1-main). Use of a CDK version which has reached end-of-support will be done at your own discretion.\n\n[AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) v2 is a single package, making it easier for you to use the CDK and stay up-to-date with the new versions. [AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) v2 consolidates the [AWS Construct Library](https://docs.aws.amazon.com/cdk/api/latest/docs/aws-construct-library.html) 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 [AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) version to use.\n\n[AWS CDK](https://aws.amazon.com/cn/cdk/?trk=cndc-detail) v2 only includes stable APIs, which comply with Semantic Versioning (semver), so you can confidently update to new minor versions. The CDK follows the “release early, release often” philosophy to encourage community participation, and we will continue deliver new features via experimental APIs for your feedback. Experimental modules will be distributed separately from ```aws-cdk-lib```versioned clearly to show their pre-release status and will only be merged into ```aws-cdk-lib```when mature and stable.\n\n[Upgrading to AWS CDK v2](https://docs.aws.amazon.com/cdk/latest/guide/work-with-cdk-v2.html) can be accomplished with a one-time safe re-bootstrapping of your AWS accounts and most projects only need to change ```import```statements.
