@@ -338,3 +338,22 @@ R0.14 (October 14, 2019)
   Fixed f_readdir() function returns file names with wrong case conversion. (appeared at R0.12)
   Fixed f_mkfs() function can fail to create exFAT volume in the second partition. (appeared at R0.12)
 
+
+R0.14a (December 5, 2020)
+  Limited number of recursive calls in f_findnext().
+  Fixed old floppy disks formatted with MS-DOS 2.x and 3.x cannot be mounted.
+  Fixed some compiler warnings.
+
+
+
+R0.14b (April 17, 2021)
+  Made FatFs uses standard library <string.h> for copy, compare and search instead of built-in string functions.
+  Added support for long long integer and floating point to f_printf(). (FF_STRF_LLI and FF_STRF_FP)
+  Made path name parser ignore the terminating separator to allow "dir/".
+  Improved the compatibility in Unix style path name feature.
+  Fixed the file gets dead-locked when f_open() failed with some conditions. (appeared at R0.12a)
+  Fixed f_mkfs() can create wrong exFAT volume due to a timing dependent error. (appeared at R0.12)
+  Fixed code page 855 cannot be set by f_setcp().
