Important Change; MySQL NDB ClusterJ: The ClusterJPA plugin for OpenJPA is no longer supported by NDB Cluster, and has been removed from the distribution. (Bug #23563810)
NDB Replication: Added a check to stop an
NDBreplication slave when configuration as a multithreaded slave is detected (for example, if
slave_parallel_workersis set to a nonzero value). (Bug #21074209)
MySQL NDB ClusterJ: Compilation for the tests for NDB JTie failed. It was due to how null references were handled, which has been corrected by this fix. (Bug #26080804)
.logfiles contained log entries for one or more extra fragments, due to an issue with filtering out changes logged by other nodes in the same node group. This resulted in a larger
.logfile and thus use of more resources than necessary; it could also cause problems when restoring, since backups from different nodes could interfere with one another while the log was being applied. (Bug #25891014)
Error 240 is raised when there is a mismatch between foreign key trigger columns and the values supplied to them during trigger execution, but had no error message indicating the source of the problem. (Bug #23141739)
