   For an overview of changes made in MySQL Cluster NDB 7.4, see MySQL
   Cluster Development in MySQL Cluster NDB 7.4
   (http://dev.mysql.com/doc/refman/5.6/en/mysql-cluster-develop
   ment-5-6-ndb-7-4.html).

   This release also incorporates all bugfixes and changes made in
   previous MySQL Cluster releases, as well as all bugfixes and feature
   changes which were added in mainline MySQL 5.6 through MySQL 5.6.24
   (see Changes in MySQL 5.6.24 (2015-04-06)
   (http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-24.html)).

   Bugs Fixed

     * During backup, loading data from one SQL node followed by
       repeated DELETE statements on the tables just loaded from a
       different SQL node could lead to data node failures.  (Bug
       #18949230)

     * When an instance of NdbEventBuffer was destroyed, any
       references to GCI operations that remained in the event buffer
       data list were not freed. Now these are freed, and items from the
       event bufer data list are returned to the free list when purging
       GCI containers. (Bug #76165, Bug #20651661)

     * When a bulk delete operation was committed early to avoid
       an additional round trip, while also returning the number of
       affected rows, but failed with a timeout error, an SQL node
       performed no verification that the transaction was in the
       Committed state. (Bug #74494, Bug #20092754) References: See also
       Bug #19873609.
