We have just shipped an updated Steam Deck Client to the Preview/Beta channel.
General
Added notification settings for showing a toast and playing a sound when an achievement is unlocked.
Merged lockscreen options 'On system wake and power up' and 'Before login screen'. Enabling the lockscreen to display 'On system wake and power up' will show the lockscreen during login.
Desktop Mode
Added a warning dialog when a user selects "Tools" in their library filter for the first time that explains what tools are and why they are showing up in the game list.
Added an icon on tools in the game list with a tooltip to explain what they are.
