How to know what new function is to be used instead a deprecated one?


developing a plugin for Elgg 1.11.0 I received messages like : Deprecated in 1.9: get_db_tables is a private function and should not be used
I would like to know if there is a way to know wich is the better (or suggested) function to substitute the deprecated one.
Is there a document with the list of deprecated functions and possile substitutes?
