Lunifier 2.1.6 Release Notes

Lunifier v2.1.6 brings comprehensive feature parity, critical reliability fixes, and layout synchronization across Windows and Linux.

What's New & Improved in v2.1.6 (Windows & Linux)

Windows: Fixed device discovery by opening HID endpoints with query access (0) instead of exclusive access, eliminating ERROR_ACCESS_DENIED and ERROR_SHARING_VIOLATION from Windows hidbth.sys / mouhid.sys. Added full recognition of Bluetooth Low Energy GATT paths ({00001812-...}) and prioritized vendor TLCs (UsagePage 0xFF43). Implemented multi-tiered Win32 write fallback (Overlapped WriteFile -> synchronous WriteFile -> HidD_SetOutputReport -> HidD_SetFeature) and 20ms connection-interval repeat bursts.
Linux: Enhanced direct Bluetooth and /dev/hidraw device handling.
Both: Added friendly device PID name mapping (M720 Triathlon, MX Master 3/3S, MX Keys/Mini, K380, K780, Craft, Lift, etc.).

Immediate Inward Stepping & Guard Arming: Cursor is immediately repositioned 160px inward and the return guard is armed as soon as the edge trigger fires before asynchronous hardware switching completes, preventing cursor pinning at border coordinates while hardware responds.
50px Deliberate Return Threshold: Increased physical mouse movement detection threshold to 50px (dx² + dy² > 2500) to prevent sensor noise and hand tremors from accidentally disarming the return guard.

Sequential Dongle Switching: Replaced concurrent parallel packet transmission to the same receiver with serialized device switching and a 30ms inter-device pause, eliminating 2.4GHz RF packet collisions on single-radio USB dongles.
Dual-Report Wake Bursts: Sends both Long Report (0x11) and Short Report (0x10) on col01, waking sleeping battery-saving keyboards so they switch alongside the mouse every time.

Windows: Added --minimized command-line switch support to start Lunifier silently in the system tray without showing the main window. Updated autostart registry configuration and Inno Setup installer tasks.
Linux: Added --minimized and --daemon argument handling in launcher, and updated ~/.config/autostart/lunifier.desktop to launch minimized on desktop login.

Advanced Tab Reorganization: Synchronized layout across Windows and Linux—renamed "Connected Devices" to "Advanced", moved "Edge Trigger Sensitivity" and "Hardware & Logging Options" into "Advanced", and added a dedicated "Save" button to the top header row.
Visual Screen Border Indicator: Implemented live orange border overlays (#FF5722, 6px thickness) with a 1.5-second auto-hide timer whenever adjusting the active zone percentage slider, changing border edge assignments, selecting a monitor, or saving configuration (WPF canvas overlay on Windows, non-blocking X11 override_redirect windows on Linux).
Package Version Parity: Synchronized all Windows (Lunifier.Windows.csproj, AppxManifest.xml, installer.iss) and Linux (pyproject.toml, lunifier/__init__.py, About window) project files to 2.1.6.
