Capabilitypublic UpdateStackRequest withCapabilities(Capability... capabilities)
A list of values that you must specify before AWS CloudFormation can update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
 The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM. The following
 resources require you to specify this parameter: 
 AWS::IAM::AccessKey, 
 AWS::IAM::Group, 
 AWS::IAM::InstanceProfile, 
 AWS::IAM::Policy, 
 AWS::IAM::Role, 
 AWS::IAM::User, and 
 AWS::IAM::UserToGroupAddition. If your stack template contains these resources, we recommend that you review
 all permissions associated with them and edit their permissions if necessary.
 
 If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you

 All events triggered by a given stack operation are assigned the same client request token, which you can use to
 track operations. For example, if you execute a CreateStack operation with the token
 token1, then all the StackEvents generated by that operation will have

 In the console, stack operations display the client request token on the Events tab. Stack operations that are
 initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify
 the stack operation . For example, if you create a stack using the console, each stack event would be assigned
