Build 0.28.2.3

Dear Patreons, thank you again for all your testing and support since 0.28.1.4. Version 0.28.2.3 moves Handheld Companion to .NET 10, drops Window 10 support, adds first-pass support for the GPD Win 5, introduces an AMD Curve Optimizer, and brings a long list of quality-of-life improvements and stability fixes across devices and UI.

Highlights

• .NET 10 & Windows 11 focus: Handheld Companion now runs on .NET 10 and, starting from this branch, targets the Windows 11 SDK only (Windows 10 is no longer supported).

• AMD Curve Optimiser: Implemented AMD CPU Curve Optimiser that lets you under- or over-volt compatible AMD devices to reduce energy consumption

Device & Controller Support

• GPD Win 5: New (WIP) device support.

• ROG XBOX Ally: Added dedicated device support for both non-X and X versions.

• MSI Claw: Better day-one experience with automatic msiapcfg deployment for the front OEM buttons, plus a fix for the 150% max fan speed issue.

• AYANEO (all devices): Added built-in AYANEO power profiles (Extreme / Balanced / Saving) that ship directly with HC and can be applied from the app.

• AYANEO Flip 1S: Fixed gyroscope readings.

• Steam Controller: Fixed IsReady / IsConnected checks.

• Steam Deck: Corrected GPU telemetry reading.

• AOKZOE / OneXPlayer (all devices): Fixed OEM button support and crashes on initialisation.

UI & Experience

Library & profiles

• You can now mark profiles as favorites from the Library page.

• Library artwork sizing was tuned for a cleaner grid, and empty executable paths are no longer allowed when saving profiles.

QuickTools & power controls

• Added a Power dropdown to QuickTools (Lock, Sleep, Shutdown, Restart).

• Battery overlay widget logic and display improved; it no longer depends on LibreHardwareMonitor.

Commands & navigation

• New Task View command and an improved Task Manager command.

• Added Copilot Voice commands; they can also resize the Copilot window.

Toasts & splash

• Toasts can now include clickable actions for richer notifications.

• Splash screen is no longer forced AlwaysOnTop, so it won’t get in your way during startup.

Power & Process Handling

Telemetry & CPU usage

• Addressed excessive CPU usage in the LibreHardware ADLX integration.

• Fixed a CPU leak when HidDevice is torn off.

Process manager hardening: The process manager now treats critical shell processes as Restricted, reducing the chance for Windows UX to interfere with our profile logic. This includes:

• Taskbar and ShellHost

• ForegroundStaging and XamlExplorerHostIslandWindow

• ApplicationManager_DesktopShellWindow

Library updates

Updated several core libraries, including SDL 3.3.2, HidHide, Sentry, LibreHardwareMonitor, WindowsAPICodePack, Nefarius.ViGEm.Client, and more, plus added detection/support for Moonlight virtual controllers.

Stability & Fixes

• Fixed a crash caused by a race condition in VirtualManager during resume from sleep.

• Fixed rare crashes linked to null controllers, null keyboard arguments, and null processEx.

• Hardened joystick-to-button / keyboard / mouse-click mappings (axis threshold logic).

• Fixed Legion Go touchpad handling (first part of a larger rework).

• Fixed missing UseOpenLib declarations that caused crashes on GPD Win devices.

• Fixed Steam Deck GPU readings and various controller stability issues.
