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

Update: This client was released again on May 18 to address some issues with controller input.

General

• Updated internal web views to Chromium v65.0.3325.181
  
• Improved responsiveness of the Steam client window when navigating the Library pane
  
• Fixed some cases where friend tags could disappear until a client restart
  
• Fixed several crash bugs found via automated crash reporting

Big Picture

• Fixed an issue where multiple button presses were required to back out of a Settings page
  
• Fixed the clock bug which caused the time to appear truncated on som...

In-Game Overlay

• Fixed an issue which caused the web browser to stop working in certain games
  
• Fixed screenshots for games built with Unreal Engine 4 in OpenGL mode
  
• Fixed some OpenGL API errors triggered by the Steam In-Game Overlay
  
• Fixed a crash in some Vulkan apps when hiding the overlay or resizing windows

Steam Input

• Enabled the Steam Controller BLE FW Update, for more information visit here: https://steamcommunity.com/games/353370/announcements/detail/2503317299191608387
  
  
• Added Switch Pro Controller Support – More info can be found here: https://steamcommunity.com/games/353370/announcements/detail/1648757912601251834
  
  
• 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.
  
• PS4 Controllers which are plugged in while already being connected wirelessly will now be ignored.
  
• Fixed input lag when starting Big Picture or starting streaming
  
• Fixed a second controller showing up briefly in games when hot-plugging a controller
  
• Changed the layout of the Polish On-screen Keyboard based on user feedback - the Polish Programmer’s keyboard layout is now used instead of the standard Polish keyboard.
  
• Fixed areas of the Steam Input Configurator where the length of the Polish localized text would cause settings to overflow past the visible portion of the screen.
  
• Updated the Steam Input API button glyph images
  
• Improved behavior of joystick auto-calibration
  
• Improved handling of controller configuration when the Steam Overlay is disabled
  
• Improved software gyro drift correction
  
• Added Gyro Enable Button Toggle. The button assigned to enable the gyro can now act as a toggle to the state rather than a hold.
  
• Added button for calibrating gyro only without doing joystick calibration
  
• Fixed a bug where newly added modes didn't always have their default settings set properly to reflect their device or placement
  
• Fixed cached controller configurations sometimes getting used on an incorrect controller when controllers were being removed and added
  
• Fixed Gyro Enable Button dropdown having appropriate options for each controller type
  
• Fixed Generic Direct Input controllers which had no guide button assigned automatically using the Back/Select button

Windows

• Fixed corrupted graphics when running on Windows 10 with desktop scaling set to 225% or higher

MacOS

• Fixed chat windows not appearing when clicking on the dock icon

Linux

• Fixed a bug where trying to re-add old Steam Library folders to the client would fail with an error about the filesystem not being mounted with execute permissions
  
• Fixed a common cause of games getting stuck when bringing up the overlay
  
• Fixed a problem where trying to resize the client window would sometimes snap back to the original size
  
• Fixed incorrect/rainbow colors when streaming from the desktop of a machine running recent Mesa
  
• Fixed low resolution in Big Picture mode due to incorrect video memory detection on Mesa

Steam Link and In-Home Streaming

• Added support for connecting to locked Windows computers, as long as Steam is running and you have access to a keyboard.
  
• Added support for interrupting a remote desktop session. Connecting will show the login screen when an RDP session is active, and logging in will disconnect RDP and start streaming the desktop normally.
  
• Removed the splash animation when launching Big Picture via Steam Link
  
• Re-added Restart/Suspend/Shutdown menu options when streaming to Steam Link
  
• Fixed black/green video for games using Unreal Engine 4 in OpenGL mode
  
• Fixed upside-down video for some OpenGL titles
  
• Changed behavior to remain in Big Picture mode if streaming is disconnected while a game is still playing

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

Last Updated April 4, 2018 with additional fixes.

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.
  
• 4-4-2018: Fixed bugs preventing workshop items or newly installed DLC from showing up on the downloads page
  
• 4-4-2018: Fixed some rare crash-on-start bugs reported via support tickets
  

Windows

• Added high-DPI monitor support when running under Windows 10 with the 2017 Creators Update
  
• Added a checkbox under Settings - Interface to disable high-DPI scaling (applies to Win10 only)
  
• Added window transition animations when opening, closing, or minimizing Steam windows
  
• Improved taskbar handling of Steam windows on multi-monitor systems
  
• Added detection and support for exFAT-formatted drives
  
• 4-4-2018: Fixed low-quality library grid images under Windows 8.1 and previous operating systems
  
• 4-4-2018: Fixed incorrect mouse cursors when resizing windows in the overlay
  

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
  
• 4-4-2018: Added support for restoring Steam Controller firmware when the controller has gone into recovery mode
  

Linux

• Added a 2X-scaling mode with high-res text and graphics when running the Steam client in desktop mode on 4k-resolution monitors. You can also force 2X scaling with the "GDK_SCALE=2" environment variable, or disable it with "GDK_SCALE=1".
  
• Added a checkbox under Settings - Interface to disable 2X scaling regardless of environment variables.
  
• Improved window-resizing interactions with the window manager
  
• Fixed an issue where the Steam client could prevent some desktop sessions from shutting down
  

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
  
• 4-4-2018: Allowed the use of touch/radial menus in native-controller-support games without going into Advanced settings
  
• 4-4-2018: Added support for displaying Mouse Regions in the Big Picture Mode Controller HUD for all input sources. The regions are either circular or rectangular matching the input source.
  
• 4-4-2018: Fixed issues where layers would have incorrect settings or UI in native-controller-support games
  
• 4-4-2018: Fixed an issue where an erroneous dialog would prompt the user to migrate configurations
  
  

In-Home Streaming

• Fixed AMD hardware capture support on R9 200/300 cards

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

Update: this client was released again on Dec 15 with additional fixes for newly reported issues.

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
  

Windows

• Fixed an issue where the Windows Mixed Reality for SteamVR drivers would sometimes not install correctly
  
• Fixed a bug where launching a game could cause the primary monitor to switch as if Big Picture mode were active, even though it is not
  

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
  

Linux

• Fixed creating desktop and application menu shortcuts
  
• Added detection and a workaround for certain titles that shipped with broken Steamworks SDK libraries
  

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.

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

Update: The client was re-released on October 31 with additional fixes for reported crashes and other minor issues.


General

• Improved stability based on top crash reports and support tickets
  
• Reduced CPU usage and battery impact when Steam is running in the background
  
• Removed notification popups when friends are using software from the "Tools" category

macOS

• Removed the need to enable special accessibility permissions for Steam
  
• Added full support for game engines using the Metal rendering API
  
• Fixed compatibility issues with some older games that crashed on startup
  
• Improved overlay support for games running at high resolution on Retina displays

Windows

• Fixed excessive blurriness in Big Picture mode on high-DPI monitors under Windows 10
  
• Improved in-game overlay compatibility with the latest Insider builds of Windows 10
  
• Added DPI-based scaling for text and basic UI elements in the in-game overlay

Steam Input

• Added Action Set Layers feature
  
  • Action Sets can now have layers nested within them. These act like Photoshop Layers on an image. Layers allow for quick modifications both big and small of an existing action set.
    
  • Each layer can draw from the actions that are defined by that action set.
    
  • Layers can be stacked arbitrarily deep.
    
  • Each layer can modify settings or replace modes/bindings of the action set or layers below it in the stack.
    
  • Changes made to the base Action Set are treated as the "default" for a layer, so modifications to a setting of the Action Set will be reflected in the layer unless it specifically modifies that setting itself. Settings within the layer that are "reset to default" will use the setting of the base action set.
    
  • Action Set Layers will be available as an option to developers creating Native Steam Input API games in a future SDK.
    
  
  
• Transitions across action sets, layers, and mode shifts will now maintain state if applicable. As an example, if the same action/output is bound across the boundaries of these sets, rather than being un-pressed and immediately pressed on this transition, it will continue to be held if bound to a pressed button in both sets.
  
• Activators which have matching Activators across action set/layer/mode shift boundaries will also carry over state, so if the same activator exists across these boundaries, a "long press" which has been pressed but not yet activated will maintain timing information. Likewise, if an output is already active coming from a previous set, a long press/double press/start press etc. which would fire the same output won't be restarted across those boundaries.
  
  
• Action set/layer activation binding now fires on the activation, rather than deactivation of the input it's attached to. The old behavior helped to prevent feedback loops of action set/layer changes, but was not in line with other input. This may be a breaking change for certain configurations, as activators like long presses will engage the action set change when the activator activates instead of when the button is released after activating, but it also matches behavior of all other bindings and fixes a number of issues with regards to various activation types. Prevention of feedback loops is now handled automatically, buttons which share action set changes on the same input will not fire when entering the new set/layer.
  
  
• Fixed unexpected D-pad right button events when other directions are rapidly tapped
  
• Fixed using On-Screen Keyboard on desktop Steam Login Screen.
  
• Fixed DS4 Gyro when streaming over a Steam Link
  
• Fixed modeshifts not properly reconciling held bindings
  
• Fixed incorrect battery readings from third-party controllers
  
• Fixed activators from different inputs being able to interrupt each other
  
• Fixed missing Calibrate button under Steam controller settings when multiple controllers are plugged in
  
• Fixed a few cases where Xbox 360 origins would not show for games using the Native API to get glyphs and text descriptions.
  
• Fixed an issue when combining gyro input with trackpad or joystick input on Linux
  
• Added A/B/X/Y buttons as options for enabling gyro input
  
• Fixed an issue where disconnected Steam Controllers that had been connected via the wireless receiver could continue to show up as connected
  
  
• On Windows, Xbox controllers not present in our current USB VID/PID Whitelist will now be detected as Xbox controllers and will fall back to using the “Xbox Configuration Support” checkbox instead of “Generic Gamepad Support”. The list of officially support Xbox and PS4 controllers can be found here on our support website. If you have a controller that is missing from this list please report it in the Steam Controller bug reports forum.

  • Changes made to the base Action Set are treated as the "default" for a layer, so modifications to a setting of the Action Set will be reflected in the layer unless it specifically modifies that setting itself. Settings within the layer that are "reset to default" will use the setting of the base action set.
    
  • Action Set Layers will be available as an option to developers creating Native Steam Input API games in a future SDK.
    
  
  
• Transitions across action sets, layers, and mode shifts will now maintain state if applicable. As an example, if the same action/output is bound across the boundaries of these sets, rather than being un-pressed and immediately pressed on this transition, it will continue to be held if bound to a pressed button in both sets.
  
• Activators which have matching Activators across action set/layer/mode shift boundaries will also carry over state, so if the same activator exists across these boundaries, a "long press" which has been pressed but not yet activated will maintain timing information. Likewise, if an output is already active coming from a previous set, a long press/double press/start press etc. which would fire the same output won't be restarted across those boundaries.
  
  
• Action set/layer activation binding now fires on the activation, rather than deactivation of the input it's attached to. The old behavior helped to prevent feedback loops of action set/layer changes, but was not in line with other input. This may be a breaking change for certain configurations, as activators like long presses will engage the action set change when the activator activates instead of when the button is released after activating, but it also matches behavior of all other bindings and fixes a number of issues with regards to various activation types. Prevention of feedback loops is now handled automatically, buttons which share action set changes on the same input will not fire when entering the new set/layer.

• Added A/B/X/Y buttons as options for enabling gyro input
  
• Fixed an issue where disconnected Steam Controllers that had been connected via the wireless receiver could continue to show up as connected
  
  
• On Windows, Xbox controllers not present in our current USB VID/PID Whitelist will now be detected as Xbox controllers and will fall back to using the “Xbox Configuration Support” checkbox instead of “Generic Gamepad Support”. The list of officially support Xbox and PS4 controllers can be found here on our support website. If you have a controller that is missing from this list please report it in the Steam Controller bug reports forum.
