We have today released v3.0.3 of BitPerfect. This is a maintenance release and serves to introduce support for DSD256 playback. This will only impact users who have a DAC capable of supporting DSD256 using DoP.
Please note that there are a small number of DACs currently on the market which only support DSD256 via ASIO (a method widely used with Windows). BitPerfect will not deliver DSD256 playback on DACs of this type unless the DAC manufacturer can provide a custom ASIO driver for OS/X (something that very few are able to do). This situation is complicated by the fact that some of those manufacturers do not do a good job of drawing the customer's attention to this limitation.
