Computed and input variables using #CurrentDate# in the expression are often used in CX surveys with closed loops to identify delayed follow-ups etc. These variables can be updated daily even without a data import/data activation.  

To preserve logic in existing computed/input variables a setting has been introduced so you can select behavior. In the image below you see the new setting (the setting appears only if the variable contains #CurrentDate# in the expression).

Here we see the new setting in the bottom of the page, tick the left option if the variable should be updated daily at 00:00 or the right if the variable shall be updated when a data activation is performed only.
