 *SVN*
 
+* Correct whitespace problem in Oracle default column value parsing.  #2788 [rick@rickbradley.com]
+
 * Destroy associated has_and_belongs_to_many records after all before_destroy callbacks but before destroy.  This allows you to act on the habtm association as you please while preserving referential integrity.  #2065 [larrywilliams1@gmail.com, sam.kirchmeier@gmail.com, elliot@townx.org, Jeremy Kemper]
 
 * Deprecate the old, confusing :exclusively_dependent option in favor of :dependent => :delete_all.  [Jeremy Kemper]
