MySQL Cluster NDB 7.0.12 was withdrawn shortly after release, due to Bug#51027. Users of the original 7.0.12 release should upgrade to MySQL Cluster NDB 7.0.12b, which fixes this issue (and others). Users of MySQL Cluster NDB 7.0.11 or MySQL Cluster NDB 7.0.11a should upgrade to MySQL Cluster NDB 7.0.11b, if they have not done so already.
This is a testing release only, for the purpose of testing the fix for Bug#49190. This release is otherwise identical to MySQL Cluster NDB 7.0.11b; users of MySQL Cluster NDB 7.0.11 or MySQL Cluster NDB 7.0.11a who are not interested in testing this change should upgrade to MySQL Cluster NDB 7.0.11b (if they have not done so already), then wait until MySQL Cluster NDB 7.0.13 becomes available.
This release also incorporates all bugfixes and changes made in previous MySQL Cluster NDB 6.1, 6.2, 6.3, and 7.0 releases, as well as all bugfixes and feature changes which were added in mainline MySQL 5.1 through MySQL 5.1.41 (see Section C.1.7, “Changes in MySQL 5.1.41 (05 November 2009)”).
