AWS CloudFormation Introduces Support for Listing Imports, Split Function, and Resource Coverage Updates
You can now use the AWS CloudFormation console to list stacks that are importing output values from another stack. Output values are used in cross-stack references, which let you import and export values between stacks without the need for hard-coding resource IDs in stack templates or passing input parameters.

You can now also use a new intrinsic function, Fn::Split, to split a string into a list of values. For example, you can use the Split function to split a single imported string of subnets exported by a network stack into a list of subnets that can be used by a load balancer.
