Universal Device Toolkit v4.2.1-preview.202606141643

Universal Device Toolkit v4.2.1

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

Universal Device Toolkit v4.2.0

Universal Device Toolkit v4.2.0

Release date: 2026-06-04

Highlights

• Stable release for in-app updates from v4.1.0. Existing installs can check for updates normally and install the Full or Online setup package from GitHub Releases.
• Added a real-time on-screen display (OSD) overlay for hardware metrics, ported from upstream Lenovo Legion Toolkit behavior.
• Rolls up post-4.1.0 fixes for God Mode preset refresh, installed optimization-only plugins, dashboard sensor loading, expanded sensor aliases, shipping-test isolation, real hardware validation guards, and broader 2020+ basic-mode device matching.

Changes

Added / 新增

• Added on-screen display (OSD) overlay with Panel and Bar styles, configurable metrics, and settings under Application behavior when hardware sensors are enabled / 新增屏幕显示（OSD）浮层，支持 Panel 与 Bar 两种样式、可配置指标，并在启用硬件传感器时于应用行为设置中提供配置入口

Fixed / 修复

• Fixed the dashboard power mode settings gear staying hidden on some Legion machines (including Y9000P 2025) when custom mode is available from hardware / 修复部分拯救者机型（含 Y9000P 2025）在硬件已支持自定义模式时，仪表盘性能模式齿轮仍无法打开设置的问题

• Fixed optimization-only plugins after install so manifest and convention-provided System Optimization child actions are visible and usable even when the plugin has no standalone page.

• Fixed dashboard CPU/GPU skeleton timing so loading remains visible until renderable live sensor data is available, and kept battery detailed average temperature out of the dashboard.

• Expanded sensor collection by including nested hardware sensors and additional CPU/GPU/platform aliases used by third-party tools.

• Fixed basic-mode device matching for broader 2020+ brand coverage, including regional brands, family-only catalog packs, and gaming subbrand DMI vendors such as ROG, Alienware, OMEN, Predator, AORUS, and ERAZER.

• Tightened shipping payload guards so test, smoke, validation, and tool projects cannot be referenced by or shipped with the main app.

• Added real hardware validation guard coverage for measurable power-mode readback instead of relying only on simulated state changes.

• Multi-platform work remains diagnostics groundwork in 4.x; formal macOS/Linux release assets are deferred to 5.x.

Universal Device Toolkit v4.1.0

Universal Device Toolkit v4.1.0

Release date: 2026-05-31

Highlights

• Fixed God Mode preset management so create, rename, delete, and preset switching refresh both the visible picker and the stored state correctly.
• Fixed optimization-only plugins so installed local plugins can contribute System Optimization child actions even when they do not expose a standalone page.
• Expanded sensor coverage and fallback handling with better VRAM, GPU hot-spot, memory temperature, SSD temperature, voltage, and shared-memory GPU readings.
• Fixed dashboard loading timing so skeletons remain visible until the first real content refresh is ready, and removed the battery detailed average temperature field.
• Continued separating hardware-validation and smoke-only behavior out of the shipping app and into standalone tools.

Changes

Improved / 改进

• Fixed God Mode preset create, rename, delete, and switching behavior so the UI and persisted state stay in sync.
• Fixed Plugin Extensions optimization-only plugins so their System Optimization child actions load correctly from installed local plugin directories.
• Expanded dashboard and fallback sensor coverage with additional VRAM, memory, SSD, voltage, hot-spot, and memory-temperature readings on more machines.
• Fixed dashboard skeleton timing so loading indicators stay visible until the first real content refresh has completed, and removed the battery detailed average temperature field.
• Continued moving hardware validation and other smoke-only behavior into standalone tools instead of shipping-app entry points.
• Prepared 4.1.0 release metadata, package-manager manifest generation, and local validation so winget/Scoop manifests can be finalized from the tagged release assets.

Universal Device Toolkit v4.0.0

Release date: 2026-05-29

Highlights

• Universal Device Toolkit is now the stable public name. Existing Lenovo Legion Toolkit installations can upgrade in place while settings, plugins, updater paths, winget, and Scoop compatibility are preserved.
• Added Full and Online release packages. Full includes bundled languages and device support data; Online starts smaller and installs language/device resources from the GitHub Pages catalog through the app flow.
• Plugin Extensions now use plugin-owned metadata and translations for names, descriptions, details, usage guides, and optimization entries.

Changes

Added / 新增

• Added a first-run language and device setup flow, including online language/device resource installation and progress feedback.
• Added broader basic-mode support for more Lenovo and non-Lenovo PCs, with device matching for common ASUS, Dell, HP, Acer, Xiaomi, Huawei, MECHREVO, Clevo/Tongfang, and generic desktop/laptop profiles.
• Added generic CPU/GPU telemetry fallbacks for basic-mode systems when Lenovo-specific sensor paths are not available.

Fixed / 修复

• Fixed language pack installation so newly selected languages are available after first launch and from Settings.
• Fixed online plugin installation so installed plugins reload correctly, show their available actions, and no longer open to a misleading "No UI" message when a settings page or optimization entry exists.
• Fixed settings-only plugins appearing as empty System Optimization categories with no actions to select.
• Fixed plugin download progress so installs continue across page navigation and queued installs show a clear waiting state.
• Fixed God Mode preset rename, create, delete, and switching persistence.
• Fixed the Device Information window leaving a large blank area when warranty details are unavailable.
• Fixed Dashboard sensor details so double-click expand/collapse works reliably across child controls.
• Fixed startup stability issues around Lenovo WMI feature reads and update banner event binding.

Improved / 改进

• Improved Plugin Extensions with collapsible details, usage guides, better spacing, and online/store metadata that stays separate from main app translations.
• Improved Dashboard sensor cards so available CPU, battery, and GPU readings stay visible instead of disappearing when one backend is unsupported.
• Improved the main left navigation with a smoother collapsed/expanded transition.
• Improved performance mode selection by keeping unsupported modes out of the picker and falling back safely when hardware reports an unavailable state.
• Improved package naming, release notes structure, SHA256 output, GitHub Pages resource catalog descriptions, and legacy installer alias handling for the rename transition.
