PSB Workstation 10.60 is intended for new workstations that are already running on Windows 10 (clean installation). The client carries the same feature level as 10.50 with added Windows 10 support. Workstations that are running on older Windows OS are not required to be updated to 10.60. Version 10.60 is expected to be released mid-August 2015.
