Release Universal Device Toolkit v4.0.0 · SSC-STUDIO/UniversalDeviceToolkit

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.

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 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 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.
