Changes in MySQL NDB Cluster 7.6.5 (5.7.20-ndb-7.6.5) (2018-04-20,
Development Milestone 5)

   MySQL NDB Cluster 7.6.5 is a new release of NDB 7.6, based on
   MySQL Server 5.7 and including features in version 7.6 of the
   NDB storage engine, as well as fixing recently discovered
   bugs in previous NDB Cluster releases.

   Obtaining NDB Cluster 7.6.  NDB Cluster 7.6 source code and
   binaries can be obtained from
   http://dev.mysql.com/downloads/cluster/.

   For an overview of changes made in NDB Cluster 7.6, see What
   is New in NDB Cluster 7.6
   (http://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-what-is-new-7-6.html).

   This release also incorporates all bug fixes and changes made
   in previous NDB Cluster releases, as well as all bug fixes
   and feature changes which were added in mainline MySQL 5.7
   through MySQL 5.7.20 (see Changes in MySQL 5.7.20
   (2017-10-16, General Availability)
   (http://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-20.html)).

Bugs Fixed

     * NDB Client Programs: On Unix platforms, the
       Auto-Installer failed to stop the cluster when ndb_mgmd
       was installed in a directory other than the default. (Bug
       #89624, Bug #27531186)

     * NDB Client Programs: The Auto-Installer did not provide a
       mechanism for setting the ServerPort parameter. (Bug
       #89623, Bug #27539823)

     * Writing of LCP control files was not always done
       correctly, which in some cases could lead to an unplanned
       shutdown of the cluster.
       This fix adds the requirement that upgrades from NDB
       7.6.4 (or earlier) to this release (or a later one)
       include initial node restarts. (Bug #26640486)

On Behalf of the MySQL/Oracle Release Engineering Team,
Hery Ramilison
