Update #2 12/21/22 - Pierre-Loup Griffais announced on Twitter that the filepath change is being rolled back and will be reintroduced next year with SteamOS 3.5. So you won’t need to reinstall or re-add anything yet.
Update 12/21/22 - It seems the new SteamOS update also changed the SD card filepath, which means EmuDeck and non-Steam games that are saved on the SD card won’t be recognized like they were previously. This will mean Re-adding or re-installing.
Valve just pushed the massive update to SteamOS out onto the stable branch for everyone to download! This update does a ton, including a bunch of fixes, a new horizontal level 2 overlay, an option to allow screen tearing, and rebasing SteamOS on a newer snapshot of Arch Linux (this is gigantic):
Rebased SteamOS on a newer snapshot of Arch Linux
- This update pulls in the latest performance, security and stability fixes for the underlying packages that are the foundation for SteamOS
- Most notably, this includes recent changes to KDE Plasma, Steam Deck's Desktop Mode. Full notes on these updates can be found on KDE's website here, here, and here. Here are a few of the highlights:
- New Overview view to see all open windows and virtual desktops
- Updates to KRunner, the built in assistant for searching and running tasks
- New touchscreen gestures
- New themes and wallpapers
- Updates to widgets
- Fixed issues with sleep affecting a small number of titles, where specific games would be frozen or exhibit glitchy behavior after waking up
- Fixed a performance issue that could cause 100ms hitches during gameplay if adaptive backlight was enabled
- Fixed a graphics driver crash when interacting with the map in DEATH STRANDING DIRECTOR'S CUT
- Fixed issue with opening file managers if the gamescope session has been restarted

- New firmware for Docking Station
- Fixes an issue where HDMI 2.0 displays are not detected during wake or boot up

- Changed performance HUD level 2 to use a horizontal layout. It fits in the letterbox space for games running in a 16:9 aspect ratio.
- Re-enabled TRIM for the internal drive as well as supported external storage devices, improving write performance
- This includes a workaround ensuring that TRIM operations are safe for SD cards that advertise discard support but do not support it

- Added an eject option for removable drives in Settings → Storage
- This unmounts the removable drive, it does not physically eject it
- External drives formatted as ext4 are now automatically mounted and available for use in Steam
- Disabled kernel DualShock 4 and DualSense trackpad → mouse emulation when Steam is running
- Changed timing of virtual keypresses to improve game compatibility with on-screen keyboard
