title: What happens when using clientVersionStalenessDays() if more updates are available?
body: <p>I'm looking into supporting in app updates, and wanted to use the google core library for handling this. While doing this a question came up regarding the clientVersionStalenessDays() function. (<a href="https://developer.android.com/reference/com/google/android/play/core/appupdate/AppUpdateInfo.html#clientVersionStalenessDays()" rel="nofollow noreferrer">https://developer.android.com/reference/com/google/android/play/core/appupdate/AppUpdateInfo.html#clientVersionStalenessDays()</a>)</p>
  <p>Say a user is running version 1 of an app, then i create a new update with version 2 which then is published to the play store. After 2 days i would expect the function to return 2 on the user device. If a new version 3 then was published on day 5 and the same function was run again would it return 5 or 0 since a new version was released the same day?</p>
