- Fix Steam Controllers sometimes turning off when reconnecting to a wireless dongle
- Fix an issue in games with multiple official controller configurations where controllers that did not have their own configuration would use the first listed configuration instead of the first compatible configuration

Steam Remote Play:
- Fix several crashes
- Fix chord combinations for back / start / thumbstick clicks on MFi controllers


Steam 16.07.2019
General:
- Improve client logic used to choose and connect to download servers, which should yield better download rates for clients with download servers close to them on the network
- Improve connection logic in friends list initialization
- Fix screenshots in SteamVR Home
- Fixed a bug where a P2P connection would not properly migrate to another relay, if the active relay went offline.
- Fixed certain web page elements continuing to render in the Steam client when it is minimized or closed to the system tray

Steam Input:
- Added mouse hover to action buttons in Configurator to display which physical buttons are related
- Rework the setting for enabling the Big Picture Mode overlay when using a Steam Input enabled controller from the desktop client. This setting now defaults to off and can be overridden on a per-game basis
- Improve handling of Switch Pro controllers when not universally opted into Steam Input - we will now toggle between DirectInput mode and the extended mode which includes gyro and rumble support depending on whether a game is using Steam Input
- Added the GetDeviceBindingRevision function, which allows developers of Steam Input API games to detect out of date user configurations. Configurations with out of date major revisions should be automatically updated by Steam to the latest official configuration, but configurations with out of date minor revisions will be left in-place.
- Added Change Player Slot binding to Steam Input. This allows a Steam Input binding to change the player’s x-input slot as seen by a game. This can be mapped to a chord for easy application across all games, and as with all bindings, be set to cycle through slots via an activator. Intended for fighting games and such where a larger set of controllers may need to be regularly and easily swapped across a limited number of player slots.
- Rework controller activity detection to require movement of joysticks/triggers instead of just deflection. Should fix wireless PS4/Switch controllers not turning off from inactivity when set down in a way that deflects the triggers or joysticks

Shader Pre-Caching:
- Re-worked the shader system to enable downloading and pre-compiling of the whole collection of Vulkan pipelines for a given game. As a result, some shader data downloads will now show in the Steam download manager. Pre-compiling will be enabled in a future Steam update
- Fixed some cases where shader depots could get downloaded even when the feature was disabled
- SteamNetworkingSockets"

Steam Input:
- Added the ability to change controller type in the “Define Layout” screen. This only affects the glyphs and configurations recommended for the device and the limits of whatever low-level API the controller is read through still apply. For example if a PS4 controller is currently treated as an Xbox controller because of a driver or non-Steam Input remapping software presenting the device over Xinput reclassifying it to a PS4 controller will only correct the glyphs and the gyro/trackpad will not work.
- Fixed an issue with devices with digital triggers and buttons bound to trigger outputs

Steam 26.03.2018
- Additional fixes


Steam 15.12.2017
- Additional fixes for newly reported issues


Steam 13.12.2017

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

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

Steam 17.10.2017
- Fixes for issues present in the original October 11 release, including a fix for black/non-responsive Store and Community pages


Steam 11.10.2017

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

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.

The list of officially support Xbox and PS4 controllers can be found here on our support website.
