AWS CloudFormation StackSets now adds support selective update operation and multiple execution roles on Stack instances

The AWS CloudFormation StackSet now allows the customers to create various multiple executive roles in target accounts. This will allow you to control the resource types users can update or create in the stack sets. You can also use the new optional parameters Regions and accounts in the updated stack set API to only update certain stack instances instead of updating the entire instance in the stack set while performing the update operations on the stack set.
