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

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)

• An internal buffer being reused immediately after it had been freed could lead to an unplanned data node shutdown. (Bug #27622643)

• 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)

• Under certain conditions, data nodes restarted unnecessarily during execution of ALTER TABLE... REORGANIZE PARTITION. (Bug #25675481)
