					General
- Fixed friends chat and other UI being visible when authorizing an in-game mictransaction
 
New Steam Chat
- Unread messages or active voice chats will now update your Steam tray/taskbar icons to indicate these statesWhen displaying a Steam store link in a chat window, extra information about the game, such as screenshots, video and price, are now displayed in the chat history
 
Windows
- Significantly improved performance and decreased memory usage for HTML based UI (Store, Community, etc) in the main Steam desktop window
 
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 outputsAdded Steam Input per-game settings to the desktop client’s game properties page.
 
In-Home Streaming
- Streaming from Mac OS X Mojave is currently disabled
