R0.02a (June 10, 2006) Added a configuration option (_FS_MINIMUM). R0.03 (September 22, 2006) Added f_rename(). Changed option _FS_MINIMUM to _FS_MINIMIZE. R0.03a (December 11, 2006) Improved cluster scan algorithm to write files fast. Fixed f_mkdir() creates incorrect directory on FAT32. R0.04 (February 04, 2007) Added f_mkfs(). Supported multiple drive system. Changed some interfaces for multiple drive system. Changed f_mountdrv() to f_mount(). R0.04a (April 01, 2007) Supported multiple partitions on a physical drive. Added a capability of extending file size to f_lseek(). Added minimization level 3. Fixed an endian sensitive code in f_mkfs(). R0.04b (May 05, 2007) Added a configuration option _USE_NTFLAG. Added FSINFO support. Fixed DBCS name can result FR_INVALID_NAME. Fixed short seek (<= csize) collapses the file object. R0.05 (August 25, 2007) Changed arguments of f_read(), f_write() and f_mkfs(). Fixed f_mkfs() on FAT32 creates incorrect FSINFO. Fixed f_mkdir() on FAT32 creates incorrect directory. R0.05a (February 03, 2008) Added f_truncate() and f_utime(). Fixed off by one error at FAT sub-type determination. Fixed btr in f_read() can be mistruncated. Fixed cached sector is not flushed when create and close without write. R0.06 (April 01, 2008) Added fputc(), fputs(), fprintf() and fgets(). Improved performance of f_lseek() on moving to the same or following cluster. R0.07 (April 01, 2009) Merged Tiny-FatFs as a configuration option. (_FS_TINY) Added long file name feature. (_USE_LFN) Added multiple code page feature. (_CODE_PAGE) Added re-entrancy for multitask operation. (_FS_REENTRANT) 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. R0.07a (April 14, 2009) Septemberarated out OS dependent code on reentrant cfg. Added multiple sector size feature. R0.07c (June 21, 2009) Fixed f_unlink() can return FR_OK on error. Fixed wrong cache control in f_lseek(). Added relative path feature. Added f_chdir() and f_chdrive(). Added proper case conversion to extended character. R0.07e (November 03, 2009) Septemberarated out configuration options from ff.h to ffconf.h. Fixed f_unlink() fails to remove a sub-directory on _FS_RPATH. Fixed name matching error on the 13 character boundary. Added a configuration option, _LFN_UNICODE. Changed f_readdir() to return the SFN with always upper case on non-LFN cfg. R0.08 (May 15, 2010) Added a memory configuration option. (_USE_LFN = 3) Added file lock feature. (_FS_SHARE) Added fast seek feature. (_USE_FASTSEEK) Changed some types on the API, XCHAR->TCHAR. Changed .fname in the FILINFO structure on Unicode cfg. String functions support UTF-8 encoding files on Unicode cfg. R0.08a (August 16, 2010) Added f_getcwd(). (_FS_RPATH = 2) Added sector erase feature. (_USE_ERASE) Moved file lock semaphore table from fs object to the bss. Fixed f_mkfs() creates wrong FAT32 volume. R0.08b (January 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 name. R0.09 (September 06, 2011) f_mkfs() supports multiple partition to complete the multiple partition feature. Added f_fdisk(). R0.09a (August 27, 2012) Changed f_open() and f_opendir() reject null object pointer to avoid crash. Changed option name _FS_SHARE to _FS_LOCK. Fixed assertion failure due to OS/2 EA on FAT12/16 volume. R0.09b (January 24, 2013) Added f_setlabel() and f_getlabel(). R0.10 (October 02, 2013) 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 value on error. R0.10a (January 15, 2014) Added arbitrary strings as drive number in the path name. (_STR_VOLUME_ID) Added a configuration option of minimum sector size. (_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. (appeared at R0.10) Fixed f_close() invalidates the file object without volume lock. Fixed f_closedir() returns but the volume lock is left acquired. (appeared at R0.10) Fixed creation of an entry with LFN fails on too many SFN collisions. (appeared at R0.07) R0.10b (May 19, 2014) Fixed a hard error in the disk I/O layer can collapse the directory entry. Fixed LFN entry is not deleted on delete/rename an object with lossy converted SFN. (appeared at R0.07) R0.10c (November 09, 2014) Added a configuration option for the platforms without RTC. (_FS_NORTC) Changed option name _USE_ERASE to _USE_TRIM. Fixed volume label created by Mac OS X cannot be retrieved with f_getlabel(). (appeared at R0.09b) Fixed a potential problem of FAT access that can appear on disk error. Fixed null pointer dereference on attempting to delete the root direcotry. (appeared at R0.08) R0.11 (February 09, 2015) Added f_findfirst(), f_findnext() and f_findclose(). (_USE_FIND) Fixed f_unlink() does not remove cluster chain of the file. (appeared at R0.10c) Fixed _FS_NORTC option does not work properly. (appeared at R0.10c) R0.11a (September 05, 2015) Fixed wrong media change can lead a deadlock at thread-safe configuration. Added code page 771, 860, 861, 863, 864, 865 and 869. (_CODE_PAGE) Removed some code pages actually not exist on the standard systems. (_CODE_PAGE) Fixed errors in the case conversion teble of code page 437 and 850 (ff.c). Fixed errors in the case conversion teble of Unicode (cc*.c). R0.12 (April 12, 2016) Added support of exFAT file system. (_FS_EXFAT) Added f_expand(). (_USE_EXPAND) Changed some members in FINFO structure and behavior of f_readdir(). Added an option _USE_CHMOD and removed an option _WORD_ACCESS. Fixed errors in the case conversion teble of Unicode (cc*.c).
