+* 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.
