下文中没有讲到的一点是为底层 Linux 添加了大量的 Locale 本地化配置，包括中文，这意味这你到手就可以将 Linux 桌面修改成中文界面，以及部分游戏（尤其是老游戏）不用再痛苦解决中文乱码问题了（比如仙剑三和仙剑四）。

仅翻译部分个人觉得比较重点的点：

SteamOS 3.5.5 has been released to the Stable channel for Deck with the following changes:

Display // 显示
The default color rendering for Steam Deck LCD has been adjusted to emulate the sRGB color gamut, resulting in a slightly warmer and more vibrant color appearance.

• Added Settings -> Adjust Display Colors, to tune the display's Color Vibrancy and Color Temperature. The settings can be tuned with a preview of a test image (above), or with your running game. // 新增设置 -> 调节屏幕色彩，来调整屏幕的饱和度和色温。可以根据一张测试图片或者运行中的游戏实时预览效果。（下面为鲜艳度的三种挡位）
  
  • Native: The native display color appearance (the color rendering for Steam Deck prior to this update).
  • sRGB: Emulate the sRGB primaries, in a smooth manner that does not introduce gradient clipping.
  • Boosted: Emulate a wider-gamut display appearance, resulting in increased apparent vibrance. May result in gradient clipping.
    
• HDR can now be enabled in Display Settings if supported by the external display. // 外置屏幕如果支持的话，可以在显示设置里面开启 HDR。
• Added HDR Analysis to Advanced Display settings.
• VRR can now be enabled in Display Settings if supported by the USB-C adapter. // 外置屏幕支持开启 VRR
• Reworked Quick-Access scaling settings to separate scaling from filtering. Added Stretch and Zoom scaling as new options to handle different aspect ratios. // 缩放模式和缩放过滤器分开为两个单独的设置。
• Fixed a long-standing issue where the internal display backlight would always stay on.
• Fixed touchscreen orientation while external display is connected.
• Compositing is now avoided in additional scenarios, reducing latency and stutter in situation with multiple overlays on sc
  

General // 通用

• Added support for Steam Deck OLED. // 添加对 Steam Deck OLED 的支持
• Fixed an issue where certain workloads would exhibit severe CPU performance issues unless SMT was manually disabled.
• External storage devices are now auto-mounted when connected to Steam Deck. To format or manage storage devices use the new device management interface in Settings->Storage.
• Updated graphics drivers, with many performance and functionality improvements. Improved performance for Starfield. Fixed viewmodel corruption in Amnesia: The Bunker and launch failures for Immortals of Aveum and Kaiju-A-GoGo. // 显卡驱动更新，大量的性能和功能性更新
• Improved Bluetooth connection stability, especially with multiple controllers
• Slightly improved sleep resume speed
• Implemented switching between controller bindings and mouse/keyboard desktop bindings by long-pressing Options in the Linux hid-steam driver, to match Steam's default Desktop configuration.
• Improved fade transitions between applications.
• The contents of the performance overlay can now be customized by creating a ~/.config/MangoHud/presets.conf configuration file.
• Fixed a bug where some games could appear stretched if their window size didn't match their swapchain size (eg. Naruto Shippuden Ultimate Ninja Storm 4)
• Fixed Disgaea PC needing to be tapped on before input works
• Fixed physical dimensions reported to games, fixing some issues with an incorrect aspect ratio sometimes being detected (eg. Returnal)
• Worked around a problem where Allow Tearing could cause heavy stuttering if the Performance Overlay or other overlays appeared on screen. Tearing is now impossible in such situations, and the Performance Overlay should be disabled for best results.
• Fixed a problem where keyboard input would not be detected in Overwatch 2
• Controller firmware: fixed an issue where some thumbstick touch sensors would lose touch periodically
  

Firmware 118 // 固件更新

• Added voltage offset settings.
  

Steam Deck Dock Firmware 121 // Steam Deck 扩展坞固件更新

• Added VRR support. // 添加 VRR 支持
• Improves reliability when changing display modes via on-screen menus
• Fixed issues with 6bpc color modes, improving high resolution/refresh mode support
• Improves detection of HDMI cable hot-plug events
  

Updated Arch Linux base // 更新底层 Arch Linux 版本

• This update pulls in newer 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 are a few of the highlights:
  
  • New window tiling system
  • Updated Discover (app store / software manager) with a new homepage and improved search
  • Discover can now perform system updates from the desktop
  • Updated desktop widgets

对应的一些影响：

• Linux 桌面支持中文，对于国内用户更友好了。
• 以前想玩一些中文老游戏必须要折腾，敲命令，现在不用了。参考 https://bbs.a9vg.com/thread-8943326-1-1.html
• 老版本的 SD 屏幕略微有些惨不忍睹，很多人都会装个插件来调整色温来提高屏幕观感。现在不需要了。
• 我看有人反馈说新的驱动，不少游戏都有一定帧数提升：https://bbs.saraba1st.com/2b/thread-2161134-1-1.html
