  • Shelves can now be deleted during reorganization by clicking on the trash can on the shelf header
  • Recent Games and Recent Friend Activity are now shelves.
  • Shelves can now be reorganized by drag and drop. Click and hold on the center of a shelf header to start reorganizing.
  • A ‘disable community content’ option has been added to Settings. Low bandwidth mode will still enable this option, but it can also be set separately.

  • Added new UI for uninstalling a game or application
  • Better support for smaller windows and restored, slimmer Home and Collections buttons
  • Replaced Home and Collections navigation buttons with Library menu options.
  • Hid empty collections from game list.
  • Added a "filter by platform" button to Linux and MacOS that will filter the current game list to only games that run on the current platform.
  • One-time reset of Steam Skin selection when receiving this beta update or when first receiving the new library update. This avoids un-updated skins causing failures when opening the new library.

  • Some Library animations now pause when the Library window does not have keyboard focus or mouse hover, even if the window may be visible

  • Fixed web view GPU acceleration to default on for Mac and Linux

  • Deleting screenshots taken in VR now also deletes the stereo version from the local disk and the cloud. Note that cloud deletion only applies to screenshots uploaded in the future, not existing shared screenshots.
  • Fixed play bar drawing over the links bar on game details when Library Sharing is active
