(_MIN_SS) 2nd argument of f_rename() can have a drive number and it will be ignored. Fixed f_mount() with forced mount fails when drive number is >= 1. Fixed f_close() invalidates the file object without volume lock. Fixed f_closedir() returns but the volume lock is left acquired. Fixed creation of an entry with LFN fails on too many SFN collisions. R0.10, Oct 02,'13 Added selection of character encoding on the file. (_STRF_ENCODE) Added f_closedir(). Added forced full FAT scan for f_getfree(). (_FS_NOFSINFO) Added forced mount feature with changes of f_mount(). Improved behavior of volume auto detection. Improved write throughput of f_puts() and f_printf(). Changed argument of f_chdrive(), f_mkfs(), disk_read() and disk_write(). Fixed f_write() can be truncated when the file size is close to 4GB. Fixed f_open(), f_mkdir() and f_setlabel() can return incorrect error code. R0.09b, Jan 24, 2013 Added f_getlabel() and f_setlabel().

R0.09, Sep 06, 2011 f_mkfs() supports multiple partition to finish the multiple partition feature. Added f_fdisk(). (_MULTI_PARTITION = 2) R0.08b, Jan 15, 2011 Fast seek feature is also applied to f_read() and f_write(). f_lseek() reports required table size on creating CLMP. Extended format syntax of f_printf(). Ignores duplicated directory separators in given path names. R0.08a, Aug 16, 2010 Added f_getcwd(). (_FS_RPATH = 2) Added sector erase feature.

R0.07e, Nov 3, 2009 Separated out configuration options from ff.h to ffconf.h. Added a configuration option, _LFN_UNICODE. Fixed f_unlink() fails to remove a sub-dir on _FS_RPATH. Fixed name matching error on the 13 char boundary. Changed f_readdir() to return the SFN with always upper case on non-LFN cfg. R0.07c, Jun 21, 2009 Fixed f_unlink() may return FR_OK on error. Fixed wrong cache control in f_lseek(). Added relative path feature. Added f_chdir(). Added f_chdrive(). Added proper case conversion to extended characters.

R0.07, Apr 01, 2009 Merged Tiny-FatFs into FatFs as a buffer configuration option. Added long file name support. Added multiple code page support. Added re-entrancy for multitask operation. Added auto cluster size selection to f_mkfs(). Added rewind option to f_readdir(). Changed result code of critical errors. Renamed string functions to avoid name collision. R0.06, Apr 01, 2008 Added f_forward. (Tiny-FatFs) Added string functions: fgets, fputc, fputs and fprintf. Improved performance of f_lseek on moving to the same or following cluster. R0.05a, Feb 03, 2008 Added f_truncate. Added f_utime. Fixed off by one error at FAT sub-type determination. Fixed btr in f_read can be mistruncated.
