As I explained in my previous post, this is documentation for software that has been obsolete for about 6-7 years at the time of writing and such documentation should not be expected to persist and cause confusion.
If you are still using the obsolete "Classic" suite, I strongly advise you upgrade to the current suite.
As for getting documentation for the old software—it should be available in your installation. Otherwise, open a support ticket and we will see what we can do for you.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
