The ndbd_redo_log_reader utility now supports a
--helpoption. Using this options causes the program to print basic usage information, and then to exit. (Bug #11749591, Bug #36805)
Cluster API: It was possible for an
Ndbobject to receive signals for handling before it was initialized, leading to thread interleaving and possible data node failure when executing a call to
Ndb::init(). To guard against this happening, a check is now made when it is starting to receive signals that the
Ndbobject is properly initialized before any signals are actually handled. (Bug #17719439)
