short_description: Create or delete an AWS CloudFormation stack
description:
- Launches or updates an AWS CloudFormation stack and waits for it complete.
notes:
- CloudFormation features change often, and this module tries to keep up. That means your botocore version should be fresh.
The version listed in the requirements is the oldest version that works with the module as a whole.
Some features may require recent versions, and we do not pinpoint a minimum version for each feature.
Instead of relying on the minimum version, keep botocore up to date. AWS is always releasing features and fixing bugs.

- boto3 >= 1.0.0
- python >= 2.6
version_added: "2.2"
