Broadcasting
Reduced latency for 1 on 1 viewing of friend broadcasts to less than a second

Big Picture Mode
Added a Big Picture Mode library filter for local multiplayer games

Steam Input
Added a “Controller Connected” notification to the desktop client for Steam Input enabled controllers. This can be disabled under Steam->Settings->Controller.
Added a “Configuration Loaded” notification to the desktop client and Big Picture when launching a game with a Steam Input enabled controller
Add action set layer visualization support to the controller HUD and the ability to bind beeps when applying/removing action set layers
Fix some cases where the Steam Input Configurator could get stuck with a blank view when previewing configurations or when deleting action sets
Fix some cases where adding/deleting action sets and action set layers could scramble which action set layer an “Apply Action Set Layer” binding points to.
Fixed modifier and volume keys not working properly as controller bindings on macOS
Added a “Platformer” variant of the gamepad template for the Steam Link Mobile Touch Controller with pre-laid out on-screen controls
