}

Expectation is that after creation of the initial version. If there are any changes made, the above code block should create new versions of the guardrail preserving the previous versions. New version creation is not happening unless the old version is deleted.

awscc version 1.16.1

Am i missing something (or) is this a bug (or) the feature is incomplete?
