-**This release contains security updates:**
-
-- **ZF2015-04:** `Zend_Mail` and `Zend_Http` were both susceptible to CRLF Injection
-  Attack vectors (for HTTP, this is often referred to as HTTP Response
-  Splitting). Both components were updated to perform header value validations
-  to ensure no values contain characters not detailed in their corresponding
-  specifications, and will raise exceptions on detection. Each also provides new
-  facilities for both validating and filtering header values prior to injecting
-  them into header classes. If you use either `Zend_Mail` or `Zend_Http`,
-  we recommend upgrading immediately.
