- 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. - Fixed f_close() invalidates the file object without volume lock. - Fixed f_closedir() returns but the volume lock is left acquired. - Fixed creation of an entry with LFN fails on too many SFN collisions.
