This is a bugfix release, fixing recently discovered bugs in the previous MySQL Cluster NDB 6.1 release.
MySQL Cluster NDB 6.1 no longer in development. MySQL Cluster NDB 6.1 (formerly known as “MySQL Cluster Carrier Grade Edition 6.1.x”) is no longer being developed or maintained; if you are using a MySQL Cluster NDB 6.1 release, you should upgrade to the latest version of MySQL Cluster, which is available from http://dev.mysql.com/downloads/cluster/ .
This Beta 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 5.1.15 (see Changes in MySQL 5.1.15 (2007-01-25)).
