Microsoft released Windows 8.1 on Oct 17th, 2013. We've been testing with Windows 8.1 for several months and have not found any issues so far. However as the final release of an OS from Microsoft may be different than previous beta builds, we will spend some time qualifying the release with our line of products that are supported on Windows 8.
Windows 8.1 is qualified with PreSonus products as of November 8, 2013. For a review of what is supported on Windows 8 see the notes below.
