-- | Creates a new version of the specified managed policy. To update a managed
-- policy, you create a new policy version. A managed policy can have up to five
-- versions. If the policy has five versions, you must delete an existing
-- version using 'DeletePolicyVersion' before you create a new version.
--
-- Optionally, you can set the new version as the policy's default version. The
-- default version is the operative version; that is, the version that is in
-- effect for the IAM users, groups, and roles that the policy is attached to.
--
-- For more information about managed policy versions, see <http://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-versions.html Versioning forManaged Policies> in the /Using IAM/ guide.
