This is a bugfix release, fixing recently discovered bugs in the previous MySQL Cluster NDB 6.2 release.
This release 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 5.1 through MySQL 5.1.51 (see Changes in MySQL 5.1.51 (2010-09-10)).
Please refer to our bug database at http://bugs.mysql.com/ for more details about the individual bugs fixed in this version.
Important Change: The
Idconfiguration parameter used with MySQL Cluster management, data, and API nodes (including SQL nodes) is now deprecated, and the
NodeIdparameter (long available as a synonym for
Idwhen configuring these types of nodes) should be used instead.
Idcontinues to be supported for reasons of backward compatibility, but now generates a warning when used with these types of nodes, and is subject to removal in a future release of MySQL Cluster.
This change affects the name of the configuration parameter only, establishing a clear preference for
[api]sections of the MySQL Cluster global configuration (
config.ini) file. The behavior of unique identifiers for management, data, and SQL and API nodes in MySQL Cluster has not otherwise been altered.
Idparameter as used in the
[computer]section of the MySQL Cluster global configuration file is not affected by this change.
