- 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)
- 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)
