+  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).

+
+
+R0.12a (July 10, 2016)
+
+  Added support for creating exFAT volume with some changes of f_mkfs().
+  Added a file open method FA_OPEN_APPEND. An f_lseek() following f_open() is no longer needed.

+  Fixed an error in the case conversion teble of code page 866. (ff.c)
+  Fixed writing data is truncated at the file offset 4GiB on the exFAT volume. (appeared at R0.12)
+  Fixed creating a file in the root directory of exFAT volume can fail. (appeared at R0.12)
+  Fixed f_mkfs() creating exFAT volume with too small cluster size can collapse unallocated memory. (appeared at R0.12)
+  Fixed wrong object name can be returned when read directory at Unicode cfg. (appeared at R0.12)

+  option       Optional external functions.
+
+
+  Low level disk I/O module is not included in this archive because the FatFs
+  module is only a generic file system layer and not depend on any specific
+  storage device. You have to provide a low level disk I/O module that written
+  to control the target storage device.
