I am using the Deco M9 plus v1 (firmware version 1.3.0) and when using the app yesterday I saw a 'there's new firmware available' notification popup.  The popup was gone as soon as it was shown after which it hasn't shown since.

Now, just suppose this wasn't a 'Google Home, coming soon'  feature and there really is an update,  I would like to know what has changed/improved/bug fixed before I even attempt to update. 

Is there any release info available that goes beyond the standard 'improved stability' ??
