Changelog

[1.3.0 Beta] - 2025-03-19

⚠ Beta Notice:
This version is a beta release and has not been fully tested. Expect potential issues, and feedback is welcome for improvements.

Added

• PC Mode: The SD card can now be directly accessed and manipulated from the host device.
  • ⚠ Important: When formatting the SD card, cluster size is critical for performance.
    • Minimum recommended cluster size: 16KB
    • Recommended cluster size: 32KB
    • Impacts: Smaller cluster sizes will directly affect SD card mounting time on the host. Additionally, all file transfer speeds (even in Legacy USB mode) are impacted by the SD card's cluster size.

Improved

• More thread-safe handling of files, improving overall stability and reliability.
• Minor optimizations to read/write commands for better performance.
