 Version 2.02.165 - 
 ===================================
+  Fix number of stripes shown in lvcreate raid10 message when too many.
   Do not monitor cache-pool metadata when LV is just being cleared.
   Add allocation/cache_pool_max_chunks to prevent misuse of cache target.
   Give error not segfault in lvconvert --splitmirrors when PV lies outside LV.
