* **New Features** * BMI270 6-axis IMU driver added; new unified filesystem abstraction for mounted filesystems. * Public Wi‑Fi API surface (no implementation yet) * SDMMC driver added (kernel drive$) * expanded GPIO interrupt/callback support * **Improvements** * M5Stack Tab5: revamped GPIO/power initialization and IMU integration. * LVGL updates including device fontSize configuration. * Updated all code related to SD card device/fs handling * Rename LilyGO T-HMI S3 to LilyGO T-HMI * **Bug Fixes** * Simplified and consolidated SD card handling and mount discovery.
