Bugs Fixed

NDB Disk Data: Stale data from NDB Disk Data tables that had been dropped could potentially be included in backups due to the fact that disk scans were enabled for these. To prevent this possibility, disk scans are now disabled—as are other types of scans—when taking a backup. (Bug #84422, Bug #25353234)
NDB Disk Data: In some cases, setting dynamic in-memory columns of an NDB Disk Data table to NULL was not handled correctly. (Bug #79253, Bug #22195588)
