 Version 2.02.78 - 
 ====================================
+  Replace snprintf with dm_snprintf in clvmd-command.c.
   Check reallocated buffer for NULL before use in clvmd do_command().
   Fix memory leak when VG allocation policy in metadata is invalid.
   Ignore unrecognised allocation policy found in metadata instead of aborting.
