The Steam Deck Stable channel just got a massive update for bug fixes, but still not the 3.5 Steam OS update everyone is waiting for...
This is primarily a Steam Desktop-focused update, many of these improvements impact Steam Deck in Steam Input, and Desktop mode
General
Fixed an issue that could result in "Steam Deck can't reach the Steam servers" errors when resuming from sleep.
Fixed an issue that prevented the steam client from immediately reconnecting to the steam servers when resuming the system from sleep.
Fixed an intermittent crash when the OS audio server restarts.
Fixed issue where a game's specific uninstall UI was not visible.
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 bell icon to the header when there are new notifications, and a green indicator to new notifications in the notifications list.
Fixed download rate limiting not working in some cases.
Fixed 'Delete Proton Files' not cleaning files that contain : in the path.

Added support for Mouse4 (Back) as B button in the interface.
Fixed opening the "Reorder controllers" dialog in the main Big Picture Window when a game is running
Search will now return tags in addition to games. You can search for categories like "Free to Play" or individual tags like "survival" or "zombies".

Restored display of Special Offers in the What's New section of the home screen.
Fixed a navigation issue in the Quick Access Menu showing the last section, instead of the Performance section, when selecting the Battery icon in the header.

Steam Input
Increase responsiveness of the "Joystick Deadzone" visualization
Gyro As Joystick can now optionally output to Left Joystick
Fixed Gyro's Left/Right Stick Deflection Modifier not working
Fixed Modeshift bindings not being removable when viewing the command on the input
Fixed a case where hitting the "apply configuration" button before a configuration preview was loaded could select the wrong configuration
Fixed a case where an autosave could get lost while editing
Fixed the DualSense configuration preview not showing Mute button bindings
Fixed bug causing DualSense triggers to only read as 0/100%
Fixed error when viewing a configuration in the "Search" tab of the config browser
Added several missing Steam Link App virtual controller-specific settings to the configurator
Added new config export path that works while offline. In personal configuration dropdown the options are now "New Personal Save", which is this new option and "New Sharable Personal Save", which uses the existing Steam Workshop backend.
Filter the configuration export options based on whether the device is connected to Steam/Offline
Fixed some flashes when adjusting sliders in the Quick Settings section of the configurator
Fixed moving right in the mode settings page not jumping to the appropriate settings sub-page
Fixed turning off the Dual Sense Edge controller
Added binding listener dialog that lets you bind inputs by hitting a mouse button, keyboard key, or gamepad button
LED Color/Brightness Action reinstated as a bindable action. Find the Action settings inside the Game Pad tab when selecting an action binding (available on controllers with LEDs only)(except Switch Pro).
Fixed cases where alt-tabbing between the stand alone instance of the desktop configurator and a game would not update the in-game layout
Added missing inputs to the "Listen" dialog
Fixed a bug where repeatedly opening the configurator to the same config could cause edits to not stick
Fix Right Trackpad Click in the controller binding listening page being bound to Left Stick Click.
Ongoing rumble is now interrupted when switching away from the app that requested it.
Reduced maximum individual SIAPI rumble requests from 10s down to 3 seconds.
Fixed crash on macOS when using a PS4 controller
Updated Controller Summary page so that it scales better at different sizes
Added mouse position dialog to configurator w/ support for transparency to the game or using your screenshots for position
Fix rotation settings when binding Gyro to Mouse output
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 to compensate.
Fixed Joystick Dead Zones in Calibration Screen triggering a controller-specific default to be used when a game was launched, instead of the value specified, if the value was less than 2048.
Fix for gyro Smoothing settings not updating when switching to shifted modes.
Fixed detection of the Steam Virtual Gamepad on macOS.
Gyroscope as Joystick/DPad/Buttons/Lean were using yaw correction-to-the-average-heading, causing subtle drift over time, especially in games which involved a lot of turning in one direction (driving games, flight sims). This was also used in GetMotionData (Steam Input API) affecting titles which used the sensor fusion quaternion for aiming. The correction toward the average has now been removed.
Deferred Sensor Fusion: Accelerometer correction (i.e. pitch correction from gravity sensors) for these modes is applied opportunistically - when the controller is rotating fast, or the controller is stationary (determined by stationary noise tolerances in the calibration page). This reduces noticeable "ouija effect" during fine aiming in our experiments. Note, none of the above gyro changes affect "Gyro As Mouse", which only uses Gyroscope readings, not Accelerometer.
The top allowed noise threshold for gyroscope in the Gyro Calibration page has been increased 3 fold to allow abnormally noisy gyroscopes to pass the drift correction/calibration process.
Remote Play
Fixed the remote player getting "host busy" dialog after the overlay is dismissed
Show MB/s instead of KB/s in the bandwidth rate settings.
Desktop Mode:

Fixed close button on the Update News dialog starting at the top of the dialog, then moving down to the bottom when the content loaded
Fixed category capsules overflowing into the app details page when the window is very narrow
Added new Achievements popup accessible from the game details page
Fixed "View Updated Items" context menu items in the Downloads section for games that have updated Workshop items
Moved 24hr time setting from Friends & Chat to Interface.

Fixed artwork modal sizing height based on screen width, fixes close button being off screen on taller images.
Fixed a case where the per-app Steam Play compatibility tool override dropdown would not appear
Added a 'Compatibility' tab to Settings where SteamPlay settings can be changed.
Steam will now use the system's global scale factor as configured in KDE settings.
Dynamically update the UI's scaling factor when the KDE system scaling setting changes.
