Update Notification

Hello,

First of all, very useful plugin!

I already figured out how to use the activate and deactivate part of the code.
I just want to ask if it’s possible to use the plugin to inform or notify the client that there is an update of the plugin they bought?
Or a notification via plugins page that there is an update?
