Added support for Unix style volume ID. (FF_STR_VOLUME_ID = 2)
Fixed accesing any object on the exFAT root directory beyond the cluster boundary can fail. (appeared at R0.12c)
Fixed f_setlabel() does not reject some invalid characters. (appeared at R0.09b)
R0.13c (October 14, 2018)
Supported stdint.h for C99 and later. (integer.h was included in ff.h)
Fixed reading a directory gets infinite loop when the last directory entry is not empty. (appeared at R0.12)
Fixed creating a sub-directory in the fragmented sub-directory on the exFAT volume collapses FAT chain of the parent directory. (appeared at R0.12)
Fixed f_getcwd() cause output buffer overrun when the buffer has a valid drive number. (appeared at R0.13b)
R0.14 (October 14, 2019)
Added support for 64-bit LBA and GUID partition table (FF_LBA64 = 1)
Changed some API functions, f_mkfs() and f_fdisk().
Fixed f_open() function cannot find the file with file name in length of FF_MAX_LFN characters.
Fixed f_readdir() function cannot retrieve long file names in length of FF_MAX_LFN - 1 characters.
Fixed f_readdir() function returns file names with wrong case conversion. (appeared at R0.12)
Fixed f_mkfs() function can fail to create exFAT volume in the second partition. (appeared at R0.12)
R0.14a (December 5, 2020)
Limited number of recursive calls in f_findnext().
Fixed old floppy disks formatted with MS-DOS 2.x and 3.x cannot be mounted.
Fixed some compiler warnings.
R0.14b (April 17, 2021)
Made FatFs uses standard library <string.h> for copy, compare and search instead of built-in string functions.
Added support for long long integer and floating point to f_printf(). (FF_STRF_LLI and FF_STRF_FP)
Made path name parser ignore the terminating separator to allow "dir/".
Improved the compatibility in Unix style path name feature.
Fixed the file gets dead-locked when f_open() failed with some conditions. (appeared at R0.12a)
Fixed f_mkfs() can create wrong exFAT volume due to a timing dependent error. (appeared at R0.12)
Fixed code page 855 cannot be set by f_setcp().
Fixed some compiler warnings.

FatFs Module Source Files R0.14b
FILES
00readme.txt This file.
00history.txt Revision history.
ff.c FatFs module.
ffconf.h Configuration file of FatFs module.
ff.h Common include file for FatFs and application module.
diskio.h Common include file for FatFs and disk I/O module.
diskio.c An example of glue function to attach existing disk I/O module to FatFs.
ffunicode.c Optional Unicode utility functions.
ffsystem.c An example of optional O/S related functions.
Low level disk I/O module is not included in this archive because the FatFs
module is only a generic file system layer and it does not depend on any specific
storage device. You need to provide a low level disk I/O module written to
control the storage device that attached to the target system.
