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 that I should no longer be using because they have been superseded or deprecated?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?

12.2 - Deprecated Features in Oracle Database 12c Release 2 (12.2)

12.1 - Deprecated and Desupported Features for Oracle Database 12c

11.2 - Behavior Changes After Upgrading Oracle Database
