Appery versus Progress

I have noticed in the docs that "Progress" is used instead of "Appery". They both appear to work so I am wondering if "Appery" will go away at some point. I have many references to "Appery" and would need to change if it is going away. I would prefer not to waste my time if it is staying.

Also,

In a recent post I was told to use the following to return the app GUID.

Progress.getProjectGUID() 

If there a way to get the app name such as;

Progress.getProjectName() 

The reference above does not work. I cannot seem to find in the docs a list of methods I can use to return app properties.
