How can I easily find out what has changed in an app after an auto update notification? When I get a notification about an app update I often wonder what changed in this update. Is there a quick &amp; easy way to find out? (No typing.)

Note: This is with auto-update enabled, when the update is already installed.
If you want to know the changes made in the app after the update then simply follow this steps.


Slide down the notification bar
Tap the update notification.
This will bring up the market link (unless you set the app to auto-update which will open up the app and not the market link because the update is already installed). 
Once you're in, search for the app in question, select it, and there you will find the changelog like this. 


Notice that you cannot do this if auto-update is enabled. You must open the Play Store, tap Menu (three dots in upper right of screen), and select My Apps. From there, do step 3.

Take note that not all developers post their changes in the market. For that you will need to google for the answer.
