For example, <code>2</code>.
The version of the plugins.zip file on your Amazon S3 bucket. You must specify a version each time a <code>plugins.zip</code> file is updated. For more information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/versioning-workflows.html">How S3 Versioning works</a>.
