+          The original file member size was lost after file was closed (see

+* The dataset created or rewritten with the v1.6.3 library or after can't 
+  be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is 
+  enabled.  There was a bug in the calculating code of the Fletcher32 
+  checksum in the library before v1.6.3.  The checksum value wasn't consistent 
+  between big-endian and little-endian systems.  This bug was fixed in 
+  Release 1.6.3.  However, after fixing the bug, the checksum value is no 
+  longer the same as before on little-endian system.  The library release 
+  after 1.6.4 can still read the dataset created or rewritten with the library
