@ -344,3 +344,26 @@ R0.14a (December 5, 2020)
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.
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.
