title: chrome storage sync, cleared on extension update?
body: <p>I am struggling to figure out whether data stored in the chrome.storage.sync, will get wiped out when ever I publish a new version of my extension through the chrome developer dashboard.</p>
  
  <p>When users of my extension gets an update (automatically), does this wipe their chrome.storage.sync? I wasn't successful in testing this.</p>
  
  <p>I am asking this because i'm developing a chrome note pad which syncs all the notes through chrome.storage.sync. I wouldn't want my users to lose their notes when i update the extension.</p>
  
  <p>The extension can be found here :
