+ * The ``ceph-kvstore-tool`` ``repair`` command has been renamed
+   ``destructive-repair`` since we have discovered it can corrupt an
+   otherwise healthy rocksdb database.  It should be used only as a last-ditch
+   attempt to recover data from an otherwise corrupted store.
  
  
 +* The default memory utilization for the mons has been increased
 +  somewhat.  Rocksdb now uses 512 MB of RAM by default, which should
 +  be sufficient for small to medium-sized clusters; large clusters
 +  should tune this up.  Also, the ``mon_osd_cache_size`` has been
 +  increase from 10 OSDMaps to 500, which will translate to an
 +  additional 500 MB to 1 GB of RAM for large clusters, and much less
 +  for small clusters.
