Added Steam Configurator support for PS4 Dual Shock Controller. Enable in Big Picture settings Add/Test Controller settings. When enabled, PS4 controllers will have access to the same sort of customization/configuration support as Steam Controllers, including native API support. PS4 Controllers using this system can map the trackpad, gyro, buttons, etc. to keyboard, mouse, or x-input outputs and can make use of action sets, touch menus, radial menus, and so forth.



Added software gyro+accelerometer integration for IMUs without hardware integration. Allows Joystick-Move/D-Pad/Mouse Leaning support for the PS4 gyro input.



Added New Mode – Joystick Mouse. This is a joystick based mouse control useful for stick based controllers.



Added controller preference setting for haptics. Haptics can now be globally disabled for a controller or default to the configuration preferences.



Added support for LED Color setting. Controllers which are capable of setting an LED color can now set this in controller personalization.



Added LED Brightness/Color controller action binding. The light on the controller can now be changed via a binding. This is useful to mark changes in state such as different action sets or mode shifts, or on start/release press activators for changing while a button is pressed, for example. Light settings are reset to user preference when changing applications/configurations.



Added software calibration for non-Steam controller based IMUs to counter for gyro drift.



Modes and bindings which are unavailable to desktop and Big Picture modes will no longer be shown in the configurator.

Fixed a bug where rumble would send to the incorrect controller and could cause controllers to control the incorrect player.



Fixed default settings not applying properly to mode shifted modes, which could cause certain parameters to be incorrect by default on mode-shifts.

A new Steam client has been released and is being automatically downloaded.
