a) It seems not possible to programatically get access to the "changes notes". Would it be possible for you to provide access to the "change notes", e.g. through a simple property? It seems that the control itself already knows how to access the "changes notes", since it's capable of displaying them (when the user clicks the control while an update is available).
b) It seems not possible for me to fetch the text strings telling about the progress of the update task ( "Downloding, 32%" etc.). I want to display those messages in a control of my own choice. I imagine you could easily provide those messages in events from the control. However, this is not a big issue (but issue a is!)

We'll add these 2 features with the next version of the AutomaticUpdater control. We'll also add a property to keep control hidden.
It will probably be out next week.
