The following feed describes important changes in each release of the AWS CloudFormation User Guide after May 2018
Modules are a way for you to package resource configurations for inclusion across stack templates, in a transparent, manageable, and repeatable way. Modules can encapsulate common service configurations and best practices as modular, customizable building blocks for you to include in your stack templates.
With change sets for nested stacks you can preview the changes to your application and infrastructure resources across the entire nested stack hierarchy and proceed with updates when you’ve confirmed that all the changes are as intended. For more information, see Change sets for nested stacks.
CloudFormation supports drift detection operations on an expanded list of AWS resources, as well as private resources that are defined as provisonable.
Registering a resource provider in your account now requires you have permission to access the schema handler package uploaded to an S3 bucket for that resource provider.
The following property was added: AWS::CodeGuruProfiler::ProfilingGroup.AgentPermissions.
Import operations now support private resource types that are provisionable; that is, whose provisioning type is either FULLY_MUTABLE or IMMUTABLE. For more information, see Resources that support import operations.
You can now use CloudFormation to perform ECS blue/green deployments through CodeDeploy. Blue/green deployments are a safe deployment strategy provided by AWS CodeDeploy for minimizing interruptions caused by changing application versions.
