AWS CDK v1 will enter Maintenance Mode after June 1, 2022

AWS CDK v1 will enter Maintenance Mode after June 1, 2022. After this date, v1 releases will contain new and updated resource level “L1” constructs, critical bug fixes, and security updates only. We will not publish new features or minor bug fixes to v1. See the AWS SDKs and Tools maintenance policy for more detail on what this means.

Maintenance mode has a duration of 12 months. On June 1, 2023, CDK v1 will reach end-of-support. After this date, the AWS CDK 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. Use of a CDK version which has reached end-of-support is done at your own discretion. We recommend you upgrade to the new major version.

To continue to get new AWS CDK features, migrate your CDK apps and construct libraries to AWS CDK v2. See this guide for details and instructions.

You can also use this tool to help you identify stacks in your account that were deployed with AWS CDK v1:

# Preload your shell with AWS credentials
npx awscdk-v1-stack-finder

# Use a profile
AWS_SDK_LOAD_CONFIG=1 AWS_PROFILE=<name> npx awscdk-v1-stack-finder
