We have changed the travel allowance setup to make it possible to set travel allowances per expense category. Until now, travel allowances were set by job title and could be overwritten on user level. Thanks to this new structure, you now set different allowances rates for different categories. This is helpful, for example, when you have a different allowance for commuting compared to the allowance for driving to a client. Of course, if the category doesn't support mileages, you can't set a travel allowance at all.
