 Version 2.02.178 - 
 =====================================
+  Add deprecate messages for usage of mirrors with mirrorlog.
   Restore pvmove support for wide-clustered active volumes (2.02.177).
   Avoid non-exclusive activation of exclusive segment types.
   Fix trimming sibling PVs when doing a pvmove of raid subLVs.
