*SVN*
+* validates_numericality_of uses \A \Z to ensure the entire string matches rather than ^ $ which may match one valid line of a multiline string. #5716 [Andreas Schwarz]
+
* Run validations in the order they were declared. #6657 [obrie]
* MySQL: detect when a NOT NULL column without a default value is misreported as default ''. Can't detect for string, text, and binary columns since '' is a legitimate default. #6156 [simon@redhillconsulting.com.au, obrie, Jeremy Kemper]
