newRPL: [UPDATED April 27-2017] Firmware for testing available for download

I thought this needs some clarification:

New SD card indicator meaning.

* SD Grayed out: Card inserted but file system not mounted yet (never used).
* SD or HC in black: Card inserted and mounted. File system is clean and card can be removed safely.
* SD or HC in inverse (white on black): File system has pending write operations or a program has at least one file open for writing. It is NOT safe to remove the card in this state. After idling for 3 seconds, the system will flush all pending operations and revert to "normal" (black on white).
* SD or HC in gray inverse (white on gray): File system still has open files but all write operations were completed. It is safe to remove the card in this state. However, it's best to make sure your programs close all files properly.
