Every time the service is in the environment, publish and API gateway will record the version of publish, which is used to provide users with the ability to switch versions. The version record contains publish's time and your Enter's publish explanation. You can view publish's version record at any time in the version page.
If you need to switch versions, select the environment to which you want to switch versions from the environment page, click switch to version in the operation, select the version you want to switch to, and click submit.
