(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.
