You can now prioritise your rules. As with occupancy rates (see below), the lower the number, the higher priority it will have over any other rules which may cover the same date span/days.
So a rule with a priority 1 will take precedence over a rule with priority 5.
Could you please check your rules, to ensure they still operate as you expect them to. As a default, they all now have a priority of 10 - so if you need one to operate above another, then please change its priority to a lower numer (higher priority).
As always, if you are unsure, please log a ticket from the control panel.
