IAM policy elements: Version

• The Version policy element specifies the language syntax rules that are to be used to process a policy.

• A policy version, on the other hand, is created when you make changes to a customer managed policy in IAM.

• IAM supports the following Version element values:

  • 2012-10-17. This is the current version of the policy language, and you should always include a Version element and set it to 2012-10-17.

  • 2008-10-17. This was an earlier version of the policy language. You might see this version on older existing policies. Do not use this version for any new policies or when you update any existing policies.

• If you do not include a Version element, the value defaults to 2008-10-17, but newer features, such as policy variables, will not work with your policy.
