Version

The Version policy element specifies the language syntax rules that are to be used to process a policy. To use all of the available policy features, include the following Version element outside the Statement element in all of your policies.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:ListAllMyBuckets",
      "Resource": "*"
    }
  ]
}

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.

note

This Version JSON policy element is different from a policy version. The Version policy element is used within a policy and defines the version of the policy language. A policy version, on the other hand, is created when you make changes to a customer managed policy in IAM. The changed policy doesn't overwrite the existing policy. Instead, IAM creates a new version of the managed policy. If you were searching for information about the multiple version support available for managed policies, see Updating a policy.
