**Features and Improvements**

- First API Stable release!
- Before this version, :meth:`cottonformation.core.model.Resource.update_tags`` only works with List of Tag typed resource tags property. Due to the historical reason, the AWS CloudFormation resource tags type definition is not consistent. I added more logic to handle both old tag type and new tag type.
- Use `aws_cloudformation <https://pypi.org/project/aws-cloudformation/>`_ library to provide better deployment user experience.

**Bugfixes**

- Special handler for appflow, some property are special type but not defined.
