There have been a few more Beta client updates, mostly concentrating on the Desktop mode again but marching closer to the 3.5 release
General
Fixed issues where some errors launching a game were not displayed, such as when an update is downloading, but there's not enough disk space available
Notification settings for the notification feed can now be set in-client from the Settings panel
Updated URL for store checkout process.
Added a bell icon to the header when there are new notifications, and a green indicator to new notifications in the notifications list.
In-Game Overlay
Fixed issue where the tabbed browser would load up web pages from a previous session when not pinned. These web pages should only be restored if the tabbed browser was pinned or when the tabbed browser is made visible.
Steam Input
Fixed certain calibration settings not saving correctly
Fixed Rumble on DualShock controllers.
Nintendo Switch Pro and JoyCons Gyroscopes now have sensitivities that are roughly equal to all other controllers as we step toward a Natural Sensitivity Scale (i.e. real world rotations result in roughly the same in-game output, regardless of controller used). Steam Input sensitivities on SwitchPro and JoyCon configurations will be automatically updated compensate.
Desktop Mode
Fixed an issue in the library causing the game released section to accidentally display for users who added the Street Fighter 6 demo to their account. This section of the library should only display when a game that you have pre-purchased is ready for pre-load or has released and is now ready to play.
Notifications now include the friend indicator overlay on user avatars when the avatar is a friend
Fixed regression where F11 was not toggling fullscreen mode correctly
Added support for notification types shown in the Desktop Client and Mobile app: Wishlist, Trade Offer, Steam Turn, Help Request, Major Sale, and Comment.
Added a tooltip to "Other" section in storage settings to explain what it contains
Fixed occasional crash when toggling a game's favorite status through the play bar on the game details page.
Fixed maximized windows intermittently being sized incorrectly
