If you’re using a DS3 on Windows you’ll have to obtain the Sony driver through PlayStation Now. Note: counterfeit Dualshock 3 Controllers will not work through this driver.
- Added a controller type drop down menu to the “Define Layout” screen for uploading user provided layouts of unrecognized controllers. If your controller is currently being treated as generic controller, but is actually a PlayStation, Nintendo, or retro controller you can upload your layouts and help us improve support for your device.

Steam Input:
- Fixed a case on macOS where the focused game window would not be detected. Note: for some games you may start getting the recommended configuration instead of the desktop configuration. Not all games on macOS support Steam Input gamepads so if your controller stops working please try changing your configuration to mouse/kb.

- Of note with Switch Pro bindings – you should use the global Nintendo Layout setting to determine your preferred layout rather than manually moving the face buttons around. This will make it easier to share configurations with other users who prefer a reversed A/B layout.
- Added support for the NACON Revolution Pro 2 PS4 controller
- Modified Steam Input to take hardware update rate of specific controllers into account when checking for input. Other improvements to the polling loop also reduce jitter and improve mouse emulation.

Steam 04.02.2018
- Change log not available for this version


Steam 03.26.2018

General:
- Reduced CPU usage of Steam when redrawing the UI, such as when the mouse is moved back and forth over part of the Library view
- Improved behavior when re-installing from retail discs or backup files, preferring to avoid downloads whenever possible
- Fixed an issue where corrupt workshop items could be re-downloaded endlessly
- Fix for new Steam Workshop item requests not being downloaded due to the “Only Allow Auto-Updates During Specific Hours” feature being enabled
- Fixed an issue where the in-game overlay could crash or become unresponsive in some Vulkan-based games
- Improved some cases where chat text was incorrectly treated as a clickable URL when it should not have been
- Fixed an issue where games could no longer be launched in offline mode if Steam had previously started or scheduled an update
- Fixed a crash when packets in a UDP connection were malformed in a particular way. Thanks to Tom Court from Context Information Security for reporting this issue.

macOS:
- Added support for turning off or restarting the system from Big Picture mode
- Improved native OS integration of Steam client windows. For example, Steam windows can now be dragged up past the menu bar to trigger the Spaces UI.
- Improved reliability of the Steam Input and Streaming Audio drivers for macOS
- Added a custom kernel driver for Sony DS4 controllers which allows use with Steam Input when connected over Bluetooth
- Improved checks for case-sensitive APFS file systems. The Steam client only supports case-insensitive file systems on macOS, and will continue to warn users when running with an incompatible file system

Big Picture:
- Fixed a browser hang when a web page transitions to or from full-screen mode

Steam Input:
- Added "Exit Application" controller action. When this action is used within a game, it will prompt the user if they actually want to quit and if confirmed will immediately close the application.
- Added Chorded Press Activator. The Chorded Press Activator requires another input to be active for it to fire. This can be combined with other activators and either interrupt them or not based on those activators settings. So a regular press can optionally fire or not based on the chorded state, while a long press can optionally interrupt both for example. Chords require the chord button to be pressed first to activate (like shift or control would on a keyboard).
- Added the ability to unique-ify configurations across Xbox and generic controllers. While the actual hardware cannot be differentiated, we treat them as unique controllers based on connection order. So if they elect to use unique configurations, configurations will be applied based on first, second, third, etc. identical controller.
- Added hardware Joystick Calibration section in Controller Settings. This allows customizing the controller joystick deadzone on a per-controller, per joystick basis. There is an auto-calibration system that attempts to determine the ideal deadzone, as well as manual sliders for overriding those values. As Xbox controllers can’t be differentiated beyond type, they will only rely on controller order. Different device types, such as an Xbox One vs and Xbox One S controller, will be differentiated.
- Made previewing state much more obvious when previewing a configuration.
- Opted-In 3rd party controllers will now detect launchers and use a launcher specific configuration that is the same as opted-out controllers.
- Improved compatibility with PS4 controller remapping programs – controllers no longer need to be reconnected when starting/exiting those programs. Also users will get a warning dialog if they are launching a game which is using the Steam Input API to support PS4 controllers while a remapper is running.
- Fixed a bug where non-Steam games would use a desktop configuration when streaming if the controller wasn’t opted into Steam Input support.
- Fixed using non-tracked gamepads in SteamVR’s Big Picture Mode overlay
- Fixed Big Picture Mode’s Disk Management screen to accept gamepad/keyboard input on the disk selection dropdown
- Fixed stuttering in some games due to excessive rumble updates
- Fixed non-Steam games not being able to take screenshots from the controller
- Fixed several layer bugs related to change layer bindings
- Added a mouse movement threshold when determining if the Guide button is being used for a chord or to hold down the button to bring up the Big Picture menu
- Fixed various On-Screen Keyboard issues including Non-Steam Controller dual cursor mode, improved language accent and modifier key support, and input immediately upon invocation
- Made Controller Options always visible in the Big Picture Mode library page, even when no controller is currently active; users will be prompted to connect a controller if none can be found.
- Fixed navigating multiple action sets via the bumper buttons when previewing a controller configuration
- Fixed a case where the Big Picture Mode overlay could receive input when not active

In-Home Streaming:
- Fixed AMD hardware capture support on R9 200/300 cards

Steam 12.15.2017
- Additional fixes for newly reported issues

Steam 12.12.2017
General:
- New feature: Shader Pre-Caching. Whenever possible, depending on hardware and driver support, Steam can download pre-compiled shaders for your specific video card. This reduces load times and in-game stuttering during the first few launches of OpenGL- and Vulkan-based games on supported hardware. This feature may use a small amount of additional bandwidth as Steam uploads and analyzes a shader usage report after each run of the game. The feature can be disabled via a new entry in the Settings dialog.
- Fixed issues with full-screen mode not scaling video content correctly in the Steam Client
- Fixed a UI issue that made it difficult to install new games if a previous installation dialog box was still active
- Fixed several rare crashes and hangs reported by customers
- Updated web views to Chromium v62.0.3202.62

macOS:
- Fixed a crash on startup that could occur if a different application was previously set to autostart, and then did not clean up its autostart entry correctly

SteamVR:
- Fixed the occasional brief appearance of a blank console window when starting Steam or launching a VR game

Steam Input:
- Changed Per-Game Steam Input opt-out setting to allow Force On or Force Off per game in addition to the global controller type based settings. This means you can turn on configuration for a single game while globally leaving configuration settings off.
- Added “Launcher Mode” for controllers which are not opted in to Steam Input Configuration. If we detect that the game is in a launcher, the right stick and right trigger will act as a mouse/trigger respectively, allowing the user to navigate the launch with a controller until they get into the game proper. This feature can be disabled by selecting the “Force Off” option in controller settings for the game in the Big Picture controls.
- Added "Always On" binding for setting bindings to take effect when an action set or layer is enabled. This can be used to set up modifier keys that are always active in a layer, changing LED brightness or color based on a set or layer, etc. and can also interact with activators to do start press behavior or turbo, for example.
- Added new tab in Configuration Browser for configs exported by your Steam Friends. These configs will now also show up in the community tab even if they would otherwise not qualify to be shown when ranked by votes or playtime. Note that only exported configs will show up, not personal configs.
- Added an "Empty Binding" binding action intended for use in layers. Essentially this is a special binding that does absolutely nothing, so bindings can be removed from a layer, as the default state of layering "nothing" means use whatever is below that layer. This special binding can also be detected by radial menus and will eliminate that item from being available in the menu.
- Added a “Remove Icon” option to the radial/touch menu icon selection screen
- Added a binding to set LED color according to Xinput slot
- Reworked detection of windows requiring Lizard Mode for the Steam Controller. Also added a bindable Lizard Mode toggle action
- Added support for several dozen Xbox-compatible controllers via data collected from users. These controllers are now treated as Xbox controllers instead of generic gamepads.
- Added support for several PS4 controllers: HORI TAC4, HORI TAC PRO, Hitbox PS4 Arcade Stick, and Venom PS4 Arcade Stick
- Fixed a configuration UI error where native actions could be selected in non-native games
- Fixed a bug where source-specific default changes weren't propagated correctly through layers
- Fixed game actions buttons being able to navigate off of their own list of actions
- Fixed some issues with typing accented and other non-english characters via the On-Screen Keyboard
- Fixed on-screen keyboard becoming stuck on-screen when controller is disconnected
- Fixed many UI focus and flow issues when configuring or personalizing a controller
- Fixed a bug with the dialog for first time config selection when a game doesn’t have a recommended config.
- Fixed several save bugs involving configurations with deleted action sets
- Fixed a bug where new developer configurations would show no buttons available to be bound
- Fixed a bug where layers of native mode types could stack incorrectly with other layers
- Fixed Big Picture configurations not accepting changes to the Face Button assignments
- Fixed Big Picture Parental PIN Pad not responding properly to controller input

Steam 10.13.2017
