A new update has been pushed out for the Steam Deck, and it brings quite a bit worth talking about.
Added support for multiple windows within one application or game.
On the client side of things, the Steam Deck has now added a PIN-based lock screen feature, localized keyboard options for an additional 21 languages and layouts, support to have multiple windows open within a single application or game, a redesigned Achievements page, new Achievement drop downs that make it easier to compare stats with friends, and more.
Meanwhile, the OS has also received various tweaks that bring about some interesting improvements.
