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.
