Changelog for the NEW Outlook?

Is there a changelog just for the NEW Outlook somewhere? Could not find one.

I tried the new one and generally liked it, but the lack of proper multi monitor support in comparison to Outlook Classic is a real blocker for me (e.g. Outlook placed on side display, double click should open an email on main display). Also the switch back to classic Outlook had side effects.

If I could follow a changelog I could try the switch when the the multi monitor features are added (hopefully).
