- Fixed a complie error when FF_FS_LOCK != 0.
- Fixed a potential issue when work FatFs concurrency with FF_FS_REENTRANT, FF_VOLUMES >= 2 and FF_FS_LOCK > 0.
- Made f_setlabel() accept a volume label in Unix style volume ID when FF_STR_VOLUME_ID == 2.
- Made FatFs update PercInUse field in exFAT VBR. (A preceding f_getfree() is needed for the accuracy)
- 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.
- Added support for UTF-8 encoding on the API. (FF_LFN_UNICODE = 2)
- Added options for file name output buffer. (FF_LFN_BUF, FF_SFN_BUF).
- Added dynamic memory allocation option for working buffer of f_mkfs() and f_fdisk().
- Fixed f_fdisk() and f_mkfs() create the partition table with wrong CHS parameters. (appeared at R0.09)
- Fixed f_unlink() can cause lost clusters at fragmented file on the exFAT volume. (appeared at R0.12c)
- Fixed f_setlabel() rejects some valid characters for exFAT volume. (appeared at R0.12)
- Changed heading character of configuration keywords "_" to "FF_".
- Removed ASCII-only configuration, FF_CODE_PAGE = 1. Use FF_CODE_PAGE = 437 instead.
- Added f_setcp(), run-time code page configuration. (FF_CODE_PAGE = 0)
- Improved cluster allocation time on stretch a deep buried cluster chain.
- Improved processing time of f_mkdir() with large cluster size by using FF_USE_LFN = 3.
- Improved NoFatChain flag of the fragmented file to be set after it is truncated and got contiguous.
- Fixed archive attribute is left not set when a file on the exFAT volume is renamed. (appeared at R0.12)
- Fixed exFAT FAT entry can be collapsed when write or lseek operation to the existing file is done. (appeared at R0.12c)
- Fixed creating a file can fail when a new cluster allocation to the exFAT directory occures. (appeared at R0.12c)
