          cell(String,String) -> cell(String,String,Comment)
        </summary-item>


<!--Security related changes:-->

        <summary-item>All security related changes from 3.10.1 (CVE-2014-3529 and CVE-2014-3574)
          are included in 3.11. Thanks to Stefan Kopf, Mike Boufford, Mohamed Ramadan,
          and Christian Schneider for their help with these.</summary-item>

        <summary-item>Please note: You should use xmlbeans-2.6.jar (as shipped with this release)
          instead of the xmlbeans-2.3.jar version from old releases to work around
          CVE-2014-3574. If you have an alternate XML parser like Apache Xerces
          in classpath, be sure to use a recent version! Older versions are likely to
          break on setting required security features.</summary-item>
