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. (July 11)
  • Fixed desktop Configurator running slowly while simultaneously running a game. (July 11)

Steam Link and In-Home Streaming
  • Fixed Rumble when streaming using a PS4 controller which is opted out of Steam Controller Support
  • Fixed Guide Button not always working properly to engage the overlay
  • Fixed desktop Configurator running slowly while simultaneously running a game. (July 11)
  • Fixed black image during 2D cutscene videos in some games (July 13)

Video Playback
  • Fixed "initializing video decoder" error that occurred on first playback of a video
  • Added a prompt to install the 360 video player when watching a 360 video for the first time

Following this Steam link will how the configuration and it can be optionally applied to the game it corresponds to. This link can be opened via a browser or at the commandline. From the command line, use "start [link]" in Windows, "open [link]" in OSX, and "xdg-open [link]" in SteamOS/Linux. Note that a controller must be active to apply a configuration. Links will be shown in the controller type they were created for, but will be converted to the controller type they are being applied to on application
