How do you find out about deprecated features in a new release of Oracle?

Friends,

If I want to know about the new features of Oracle 11gR2 Database I can use the New Features Guide.

Is there such a guide that lists functionality, features, parameters etc. that I should no longer be using because they have been superseded or deprecated?

If there isn't such a guide, which I suspect, what do you do to find out what has been deprec开发者_如何学Goated in the next release of the database?
