-Active Record supports multiple table foreign key relationships with the restriction
-that each relationship corresponds to a unique table. For example, the <tt>Players</tt>
-table may only have one set of foreign key relationship with table <tt>Teams</tt>, it may
-have other relationships that corresponds to other tables (including the <tt>Players</tt> table itself).
+Since version <b>3.1.2</b>, Active Record supports multiple foreign key 
+references of the same table. Ambiguity between multiple foreign key references to the same table is
+resolved by providing the foreign key column name as the 3rd parameter in the relationship array. 
+For example, both the following foreign keys <tt>owner_id</tt> and <tt>reporter_id</tt>
+references the same table defined in <tt>UserRecord</tt>.
