Edit: I got tired of waiting and seeing questions on my stuff go unanswered so I took my GitHub fork and made it compatible. It is not in the appstore yet but you can take the mpk here:
Just drop it in the widgets folder of your project, replacing the one already there and you should be fine.
I tested on Mx 6.5.1
Hello , Yes finally the new version 3.0 is released in the App store today. It is still waiting for approval but will be there this week. – marco groenenberg (2016-07-19) Enjoy the widget!
