Ungültiger Standardwert (MySQL 5.7) für das Zeitstempelfeld

BEARBEITEN: Wenn Sie eine vorhandene Datenbank von MySQL 5.6 aktualisieren und ausführen:

UPDATE phppos_register_log SET shift_end = '2015-01-01 00:00:00' WHERE shift_end = '0000-00-00 00:00:00';

Dies erzeugt:

#1292 - Incorrect datetime value: '0000-00-00 00:00:00' for column 'shift_end' at row 1
#1067 - Invalid default value for 'shift_start' 

Dies funktionierte in MySQL <= 5.7. Ich konnte keine Dokumentation dazu finden ... Was ist das Problem damit?

      `register_log_id` int(10) NOT NULL AUTO_INCREMENT,
