Steam Client Update Released
Client Update - Valve
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.

Steam Client Update Released
Client Update - Valve
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.

Steam Client Update Released
Client Update - Valve
A new Steam client has been released and is being automatically downloaded.

UPDATE: This client version was re-released on July 17 with some additional fixes, listed below.

General
  • Updated web control to CEF v60.0.3112.10
  • Removed requirement of having a saved credit card when purchasing in-game recurring subscriptions
  • Fixed missing game names for users with large Steam libraries
  • Fixed custom launch arguments not applying when launching 3rd-party Half-Life or Half-Life 2 mods
  • Fixed games failing in offline mode with errors such as "servers are too busy" or "currently no licenses available"
  • Decreased latency for some network operations in the Steam Client
  • Improved Steam client connectivity on networks where custom UDP/TCP ports are blocked
  • Fixed a crash when handling steam:// URLs launched from a browser (July 11)
  • Added detection and workaround for crashes on startup caused by certain antivirus/anti-malware programs (July 13)
  • Fixed an issue where Store and Community pages could forget your Steam language settings after a while (July 13)
  • Fixed multiple issues where the Steam client could hang or crash on startup (July 17)

macOS
  • Fixed a rare crash on shutdown or when exiting Big Picture mode (July 11)

Steam Input
  • Added Enhance Small Movement Precision setting to Mouse Joystick Mode. This allows for a fine tuning of low end movements so you can balance between fine grain control and minimum speed cutoff, resulting in a smoother response and less jumpy movement at slow speeds. Should be used in tandem with Minimum X/Y Output. This feature is enabled by default, but previous behavior can be restored by setting to the minimum value.
  • Added Custom Curve setting to Mouse Joystick Mode. This allows for compensation for game joystick response curves to more accurately dial in Mouse Joystick feel on a per-game basis.
  • Reworked the first time controller setup process for games without a recommended config provided by the publisher. We will now suggest the top community config if it meets the required confidence threshold.
  • Re-enabled layout definition of DirectInput controllers. The new interface uses the “Define Layout” button in the Controller Settings Page.
  • Added battery level indication for Xinput and PS4 controllers. When the battery is below 25% a low battery indicator will show in the Big Picture main menu. Clicking this indicator will rumble or play an identify chime on the low battery controller.
  • Fixed a bug where controllers using Xinput could have rumble output swapped.
  • Fixed a bug where controller configs would be applied to the last used controller instead of the selected one.
  • Fixed available offline personal and template bindings not appearing in the config browser when offline.
  • Improved XBox One default deadzone.
  • Removed Toast stating “Using Configurations for [X]” when the user was opted out for said controller.
  • When changing XInput slots for a controller which isn’t registered, show the controller type rather than trying to use a name.
  • Added Overlap Region setting to 8-Way and Analog Emulation D-Pad modes. This region specifies what proportion the diagonal overlapping region takes up relative to the cardinal directions.
  • Improved gyro precision and stability over time
  • PS4 Controller Gyro now uses hardware calibration instead of software calibration. This should improve general drift performance and no longer requires the Calibration step in Steam.
  • Added check for InputMapper and DS4Windows on connection of PS4 Controllers. If either program is running Steam will ignore the controller until it is reconnected.
  • Fixed a bug where configurations might not be applied if a controller went from being wireless to wired or vice-versa within a single session
  • Fixed a bug where configurations wouldn’t be saved if controller identity couldn’t be established properly
  • Fixed bug in Big Picture Overlay which prevented users from switching between which controller was being configured when multiple controllers were connected
  • Fixed bug in Big Picture Login Screen where On-Screen Keyboards would lose touchpad input on the password entry screen

  • Fixed several issues with XInput emulation when using Steam Controllers and streaming controllers (July 11)

Steam Client Update Released
Client Update - Valve
A new Steam client has been released and is being automatically downloaded.

UPDATE: This client version was re-released on July 17 with some additional fixes, listed below.

General
  • Updated web control to CEF v60.0.3112.10
  • Removed requirement of having a saved credit card when purchasing in-game recurring subscriptions
  • Fixed missing game names for users with large Steam libraries
  • Fixed custom launch arguments not applying when launching 3rd-party Half-Life or Half-Life 2 mods
  • Fixed games failing in offline mode with errors such as "servers are too busy" or "currently no licenses available"
  • Decreased latency for some network operations in the Steam Client
  • Improved Steam client connectivity on networks where custom UDP/TCP ports are blocked
  • Fixed a crash when handling steam:// URLs launched from a browser (July 11)
  • Added detection and workaround for crashes on startup caused by certain antivirus/anti-malware programs (July 13)
  • Fixed an issue where Store and Community pages could forget your Steam language settings after a while (July 13)
  • Fixed multiple issues where the Steam client could hang or crash on startup (July 17)

macOS
  • Fixed a rare crash on shutdown or when exiting Big Picture mode (July 11)

Steam Input
  • Added Enhance Small Movement Precision setting to Mouse Joystick Mode. This allows for a fine tuning of low end movements so you can balance between fine grain control and minimum speed cutoff, resulting in a smoother response and less jumpy movement at slow speeds. Should be used in tandem with Minimum X/Y Output. This feature is enabled by default, but previous behavior can be restored by setting to the minimum value.
  • Added Custom Curve setting to Mouse Joystick Mode. This allows for compensation for game joystick response curves to more accurately dial in Mouse Joystick feel on a per-game basis.
  • Reworked the first time controller setup process for games without a recommended config provided by the publisher. We will now suggest the top community config if it meets the required confidence threshold.
  • Re-enabled layout definition of DirectInput controllers. The new interface uses the “Define Layout” button in the Controller Settings Page.
  • Added battery level indication for Xinput and PS4 controllers. When the battery is below 25% a low battery indicator will show in the Big Picture main menu. Clicking this indicator will rumble or play an identify chime on the low battery controller.
  • Fixed a bug where controllers using Xinput could have rumble output swapped.
  • Fixed a bug where controller configs would be applied to the last used controller instead of the selected one.
  • Fixed available offline personal and template bindings not appearing in the config browser when offline.
  • Improved XBox One default deadzone.
  • Removed Toast stating “Using Configurations for [X]” when the user was opted out for said controller.
  • When changing XInput slots for a controller which isn’t registered, show the controller type rather than trying to use a name.
  • Added Overlap Region setting to 8-Way and Analog Emulation D-Pad modes. This region specifies what proportion the diagonal overlapping region takes up relative to the cardinal directions.
  • Improved gyro precision and stability over time
  • PS4 Controller Gyro now uses hardware calibration instead of software calibration. This should improve general drift performance and no longer requires the Calibration step in Steam.
  • Added check for InputMapper and DS4Windows on connection of PS4 Controllers. If either program is running Steam will ignore the controller until it is reconnected.
  • Fixed a bug where configurations might not be applied if a controller went from being wireless to wired or vice-versa within a single session
  • Fixed a bug where configurations wouldn’t be saved if controller identity couldn’t be established properly
  • Fixed bug in Big Picture Overlay which prevented users from switching between which controller was being configured when multiple controllers were connected
  • Fixed bug in Big Picture Login Screen where On-Screen Keyboards would lose touchpad input on the password entry screen
  • Fixed bug where only Mouse/KB prompts were shown in the Desktop Client’s Controller Configurator
  • Fixed bug where PS4 Controller registrations would not carry over from MacOS to Windows or Linux and vice-versa
  • Fixed several bugs with settings and configuration UI
  • Fixed several issues with XInput emulation when using Steam Controllers and streaming controllers (July 11)
  • Fixed multiple controllers sharing the same XInput slot in some circumstances (July 11)
  • Fixed controllers changing what slot they occupied when removing and plugging in new controllers - this preserves the behavior that the first controller used ends up in the first XInput slot, the second in the second slot, etc. If 4 controllers are connected while Streaming and a local controller is available, if a remote controller is disconnected, the local controller will seamlessly drop into that slot when used.
