## FlexDesigner

Touch Bar integration is more reliable (native init and API fallbacks).
Media features no longer get stuck when fetching on macOS; playback path and listener shutdown are cleaned up.
Page switching follows the focused app more sensibly on macOS (window monitor behavior).
USB transfer, hardware monitor (including non-English environments), and Adobe Premiere-related flows are improved.
Bundled submodules and packaging are updated to **2.2.2**, with refreshed firmware bundle and build metadata.
Fixes multi-chunk HID receive buffers by sizing them from `pack_size` and accepting channel 1 data.
Exposes `sendControlCommand` IPC for plugin UI iframes, allowing plugin UIs to send control commands through the host.
Runs Windows AutoHotkey commands with `execFile` instead of shell execution for more reliable command launching and argument handling.
Reworks Windows hardware monitor data into short sensor keys and a flat LibreHardwareMonitor payload while bounding retained `hwData`.
Migrates legacy performance-chart LibreHardwareMonitor paths to the new short-key format.

## Flexbar

USB data path is more robust (DMA-backed pools and clearer CDC bulk behavior).
The device wakes correctly after the host starts; scroll wheel no longer sticks in bad cases.
Adobe Premiere timeline usage on device is extended (handling and resources).
Factory default data is safer for the UI stack; release artifacts are split into clearer binary layout and tagged for this generation.
Stages CDC IN transfers and tightens CDC send handling for more stable USB communication.
Stabilizes the DirectDraw lifecycle, including receiver shutdown and plugin DirectDraw cleanup.
Updates the hardware monitor data receiver path to align with the refined USB transfer behavior.
