Steam Client Update Released

Client Update - Valve

Oct 11, 2017

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.
