-**This release contains security updates:**
-
-- **ZF2016-03:** The implementation of `ORDER BY` and `GROUP BY` in
-  `Zend_Db_Select` remained prone to SQL injection when a combination of SQL
-  expressions and comments were used. This release provides a comprehensive
-  solution that identifies and removes comments prior to checking validity of
-  the statement to ensure no SQLi vectors occur. We advise always filtering user
-  input prior to invoking these methods, however, to further protect your
-  applications.
