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)).
Please refer to our bug database at http://bugs.mysql.com/ for more details about the individual bugs fixed in this version.
The wrong data pages were sometimes invalidated following a global checkpoint. (Bug #29067)
An invalid comparison made during
validation that could lead to an Error while reading
REDO log condition.
If at least 2 files were involved in
invalidation, then file 0 of page 0 was not updated and so
pointed to an invalid part of the redo log.
When a node failed to respond to a
signal as part of a global checkpoint, the master node was
killed instead of the node that actually failed.
Disk Data: When dropping a page, the stack's bottom entry could sometime be left “cold” rather than “hot”, violating the rules for stack pruning. (Bug #29176)
