title: iOS App Version Numbering
body: <p>The iTunes Connect Developer Guide PDF (page 47), refers to the following on the version number of an iOS app:</p>
  
  <blockquote>
    <p>Use typical software versioning conventions (such as “1.0" or
    "1.0.1" or "1.1”)</p>
  </blockquote>
  
  <p>There is no statement about the exact format  of the app version number. Can we use version numbers such as "1.0.0.1" or "1.0.0.0.1"?</p>
