-* OSDMap's json-formatted dump changed for keys 'full' and 'nearfull'.
-  What was previously being outputted as 'true' or 'false' strings are
-  now being outputted 'true' and 'false' booleans according to json syntax.
-
-* HEALTH_WARN on 'mon osd down out interval == 0'. Having this option set
-  to zero on the leader acts much like having the 'noout' flag set.  This
-  warning will only be reported if the monitor getting the 'health' or
-  'status' request has this option set to zero.

-* Librados interface change:  As there are no partial writes, the rados_write()
