If not present during a\n`ModifyPushConfig` call, its value will not be changed. `GetSubscription`\ncalls will always return a valid version, even if the subscription was\ncreated without this attribute.\n\nThe possible values for this attribute are:\n\n* `v1beta1`: uses the push format defined in the v1beta1 Pub/Sub API.\n* `v1` or `v1beta2`: uses the push format defined in the v1 Pub/Sub API.",
