Update notification screen

I want this feature as found it useful.

Is currently there any way, except cloud messaging, users can be informed through app that updated version has been published, so kindly update it to use new features?

If there is nothing regarding this, then there should appear an screen message with playstore/itunes link whenever app’s updated version is published on playstore/itunes, showing information about updated version, new features, bugs resolved and so on.

Humble regards
Raja Sand
