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.
