+R0.13b (April 07, 2018)\r
+  Added support for UTF-32 encoding on the API. (FF_LFN_UNICODE = 3)\r
+  Added support for Unix style volume ID. (FF_STR_VOLUME_ID = 2)\r

+R0.13a (October 14, 2017)\r
+  Added support for UTF-8 encoding on the API. (FF_LFN_UNICODE = 2)\r
+  Added options for file name output buffer. (FF_LFN_BUF, FF_SFN_BUF).\r
+  Added dynamic memory allocation option for working buffer of f_mkfs() and f_fdisk().\r
+  Fixed f_fdisk() and f_mkfs() create the partition table with wrong CHS parameters. (appeared at R0.09)\r
+  Fixed f_unlink() can cause lost clusters at fragmented file on the exFAT volume. (appeared at R0.12c)\r

+\r
+R0.13 (May 21, 2017)\r
+  Changed heading character of configuration keywords "_" to "FF_".\r
+  Removed ASCII-only configuration, FF_CODE_PAGE = 1. Use FF_CODE_PAGE = 437 instead.\r
+  Added f_setcp(), run-time code page configuration. (FF_CODE_PAGE = 0)\r
+  Improved cluster allocation time on stretch a deep buried cluster chain.\r
+  Improved processing time of f_mkdir() with large cluster size by using FF_USE_LFN = 3.\r
+  Improved NoFatChain flag of the fragmented file to be set after it is truncated and got contiguous.\r
+  Fixed archive attribute is left not set when a file on the exFAT volume is renamed. (appeared at R0.12)\r
+  Fixed exFAT FAT entry can be collapsed when write or lseek operation to the existing file is done. (appeared at R0.12c)\r
+  Fixed creating a file can fail when a new cluster allocation to the exFAT directory occures. (appeared at R0.12c)\r
+\r
+R0.12c (March 04, 2017)\r
+  Improved write throughput at the fragmented file on the exFAT volume.\r
+  Made memory usage for exFAT be able to be reduced as decreasing _MAX_LFN.\r
+  Fixed successive f_getfree() can return wrong count on the FAT12/16 volume. (appeared at R0.12)\r
+  Fixed configuration option _VOLUMES cannot be set 10. (appeared at R0.10c)\r
