operational efficiency (such as enhanced reporting and faster restarts
and upgrades) and conflict detection and resolution for active-active
replication between MySQL Clusters.

Changes in MySQL Cluster NDB 7.4.10 (5.6.28-ndb-7.4.10) (2016-01-29)
 
   MySQL Cluster NDB 7.4.10 is a new release of MySQL Cluster
   7.4 which fixes a major performance regression found in MySQL
   Cluster NDB 7.4.8 which also affected MySQL Cluster NDB
   7.4.9. Users of previous releases of MySQL Cluster can and
   should bypass the 7.4.8 and 7.4.9 releases when performing an
   upgrade, and upgrade directly to MySQL Cluster NDB 7.4.10 or
   later.

   Obtaining MySQL Cluster NDB 7.4.  MySQL Cluster NDB 7.4
   source code and binaries can be obtained from
   http://dev.mysql.com/downloads/cluster/.

   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 MySQL Cluster NDB 7.4.9 and previous MySQL Cluster
   releases, as well as all bugfixes and feature changes which
   were added in mainline MySQL 5.6 through MySQL 5.6.28 (see
   Changes in MySQL 5.6.28 (2015-12-07)
   (http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-28.h
   tml)).

   Bugs Fixed

    * A serious regression was inadvertently introduced whereby
       local checkpoints and thus restarts often took much
       longer than expected. This occurred due to the fact that
       the setting for MaxDiskWriteSpeedOwnRestart was ignored
       during restarts and the value of
       MaxDiskWriteSpeedOtherNodeRestart, which is much lower by
       default than the default for MaxDiskWriteSpeedOwnRestart,
       was used instead. This issue affected restart times and
       performance only and did not have any impact on normal
       operations. (Bug #22582233)
