+                       Added string functions: fputc(), fputs(), fprintf() and fgets().
+                       Improved performance of f_lseek() on move to the same or following cluster.
+
+  Apr 01, 2009, R0.07  Merged Tiny-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.
+
+  Apr 14, 2009, R0.07a Separated out OS dependent code on reentrant cfg.
+                       Added multiple sector size support.
+
+  Jun 21, 2009, R0.07c 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 for extended characters.
+
+  Nov 03,'2009 R0.07e  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.
