Release Universal Device Toolkit v4.2.1 · SSC-STUDIO/UniversalDeviceToolkit

Release date: 2026-06-07

Highlights

Redesigned the dashboard home page for large windows: sensor sections now show radial gauges and live CPU/GPU trend charts with a legend, battery capacity is visualized with rings, and the dashboard groups reflow into 1, 2, or 3 columns based on window width so content no longer stretches awkwardly when maximized / 重新设计大窗口下的仪表盘主页：传感器区域改用环形仪表盘并加入带图例的 CPU/GPU 实时趋势图，电池容量以环形图展示，仪表盘分组会根据窗口宽度自适应为 1、2 或 3 列，最大化时内容不再被拉伸失真
Fixed a startup crash when a damaged dashboard settings file contains empty sensor/dashboard groups / 修复仪表盘设置文件损坏并包含空传感器/仪表盘分组时的启动崩溃
Fixed dashboard and console sensor loading so partial CPU/GPU readings stay visible, intermittent missing metrics no longer flash, and subsequent opens reuse cached data in the same app session / 修复仪表盘和控制台传感器加载，部分 CPU/GPU 读数会保持显示、偶发缺失的指标不再闪烁，并且同一次应用运行中的后续打开会复用缓存数据
Fixed GPU power readings flickering to unavailable and restored battery current and average temperature display / 修复 GPU 功耗读数闪烁为不可用的问题，并恢复电池当前温度和平均温度显示
