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.

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.
