InnoDB
|

tablespace encryption requires the

plugin to be loaded prior to

InnoDB

initialization, so this change of default value introduces an incompatibility for upgrades from 5\&.7\&.11 to 5\&.7\&.12 or higher\&. Administrators who have encrypted
|

InnoDB

tablespaces must take explicit action to ensure continued loading of the
