How to alert user upon update of chrome app?

I have a chrome app that I am going to be updating and the update will break previous saves. Now I would like to alert the users of the app upon successful completion of the update. I do have an chrome api that I am trying to use which is:

chrome.runtime.onInstalled.addListener(function(){

});

Now I have read the chrome.runtime developer docs and it says that I can use:

chrome.runtime.onInstalled.addListener(function callback)

With a callback function of:

function(object details) {...};

The problem is that I can not figure out what exactly to do with the info as I have tried a couple of different set ups with this code but none work. any help with this issue would be appreciated

Please note that I am trying to display a window that would contain this message. Also my current code is in the background.js of my app although as said the code does not work.

Documentation mentions one property of details:

reason

enum of "install", "update", "chrome_update", or "shared_module_update"

The reason that this event is being dispatched.

So your code needs to check that:

chrome.runtime.onInstalled.addListener(function(details){
  if(details.reason == "update") {
    // Inform the user of the sad news
  }
});
