- 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)
- 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.
- 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)
