Breaking: #63784 - Visibility and type of DataHandler->exclude_array¶
The internal but formerly public property DataHandler->exclude_array is replaced by the protected property DataHandler->excludedTablesAndFields, which contains the combination of excluded table and field as key instead. This improves performance especially for bulk editing since many in_array()-checks can be avoided.
Extensions using the DataHandler (former TCEMain) and changing the (former public) exclude_array to change access to tables and fields cannot do so anymore. Users need to have their access-rights set properly instead.
Installations using extensions that read or write the undocumented array exclude_array.
Remove code accessing DataHandler->exclude_array and configure the BE-User properly.
