Description: 

In previous versions the 'group_column' could be left empty in field settings for Views.

This will no longer be supported.

Modules providing default Views should update their configuration by importing the Views, saving them and exporting them, this set the 'group_column' to the default value for the field type.

Site builders, administrators, editors
