Bugs Fixed

• Agent: mcmd quit unexpectedly sometimes while trying to back up a large cluster. (Bug #36675015)

• Client: MySQL Cluster Manager did not handle correctly the version information for some cluster parameters' introduction or removal, so that it was sometimes confused with the availability of those parameters for a cluster. (Bug #36647522)

• Client: When ndb_restore failed, the error message did not give much information. With this patch, a more informative message is given in the situation. (Bug #36388952)

• Client: The format of the mysqld XML configuration file (mcm-installation-dir/var/mysqld.xml) has been updated to better organize the configuration information. (Bug #36298214)

• Certain restrictions for upgrading and downgrading on MySQL Cluster Manager have been removed. Please refer to Upgrading and Downgrading NDB Cluster for valid upgrade and downgrade paths for MySQL NDB Cluster and MySQL Cluster Manager. (Bug #36610348, Bug #36720575)

• Some Windows binaries for MySQL Cluster Manager had wrong or missing version or product name information under its Properties. (Bug #36510070)
