@ -357,3 +357,13 @@ R0.14b (April 17, 2021)
Fixed some compiler warnings.
R0.15 (November 6, 2022)
Changed user provided synchronization functions in order to completely eliminate the platform dependency from FatFs code.
FF_SYNC_t is removed from the configuration options.
Fixed a potential error in f_mount when FF_FS_REENTRANT.
Fixed file lock control FF_FS_LOCK is not mutal excluded when FF_FS_REENTRANT && FF_VOLUMES > 1 is true.
Fixed f_mkfs() creates broken exFAT volume when the size of volume is >= 2^32 sectors.
Fixed string functions cannot write the unicode characters not in BMP when FF_LFN_UNICODE == 2 (UTF-8).
Fixed a compatibility issue in identification of GPT header.

Features and Limitations:
* Easy to Port Bit-banging SPI
It uses only four GPIO pins. No complex peripheral needs to be used.
* Platform Independent
You need to modify only a few macros to control the GPIO port.
* Low Speed
The data transfer rate will be several times slower than hardware SPI.
* No Media Change Detection
Application program needs to perform a f_mount() after media change.
