The UPDATE statement wrote NULL when the column set is DATETIME and value is '0000-00-00 00:00:00'. The problem was inside WriteEngine's handling of UPDATE statements and this is where heart of change is. Other changes are related to some obsolete data structures in DML/DDL handling that just hanging around there, doing nothing.
