Easier Unallocation/'Parking' - Remove a reservation item (booking) from a room with a right click or by dragging. Please see here for some more information about unallocated reservation items.
Improved Revenue Report - You can now compare multiple years and export the data on the Revenue Report, which you will find under Reports -> Revenue Report.
City/Property Tax - For those countries that must include city taxes for guests staying, these taxes are now displayed automatically when a guest is booking and on any confirmations. You can still specify the amount of city tax when creating the bill. Please ensure the per person per night price for your property/city tax is correct. This can be checked at Rates->Tax Rates. At the bottom of that page you will see Property Taxes.
