The new HTML5 Control Panel contains an option to add and maintain Deny & Allow List.
The current Control Panel version contains the option to set such lists, but any list currently set there is without any function for the time being. Once the Deny & Allow List function has been enabled for the new Control Panel, any lists already setup in the old Control Panel will be automatically implemented.
Any Deny & Allow List existing in the new Control Panel will be overwritten once the data will me migrated from the old Control Panel. Therefore, we recommend maintaining the Deny & Allow List from the old Control Panel exclusively, for the time being.
