The new forms don't have this behavior as of yet to my knowledge (or at least the last time I checked) - you will have to find a workaround for now by freezing the old value into a field on the form and then comparing. So that might look like:
- A rule that when the record is saved - store the value of your field into a 'Freeze' field
- Before rule (1) fires - compare the current value of the field to the freeze value and if it fails your test abort the save - otherwise let it through and allow the above rule to fire so the freeze value resets.
