+*** Default =small_vclock= to be equal to =big_vclock=
+
+If you are using bidirectional cluster replication and you have
+overridden the defaults for either of these then you should consider
+setting both to the same value.
+
+The default value of =small_vclock= has been changed to be equal to
+=big_vclock= in order to delay or even prevent unnecessary sibling
+creation in a Riak deployment with bidirectional cluster replication.
+When you replicate a pruned vector clock the other cluster will think
+it isn't a descendent, even though it is, and create a sibling. By
+raising =small_vclock= to match =big_vclock= you reduce the frequency
+of pruning and thus siblings. Combined with vnode vclocks, sibling
+creation, for this particular reason, may be entirely avoided since
+the number of entries will almost always stay below the threshold in a
+well behaved cluster (i.e. one not under constant node membership
+change or network partitions).
