this behavior should be updated.

Release Notes
===============
+v0.74
+-----
+
+This release includes a few substantial pieces for Firefly, including
+a long-overdue switch to 3x replication by default and a switch to the
+"new" CRUSH tunables by default (supported since bobtail). There is
+also a fix for a long-standing radosgw bug (stalled GET) that has
+already been backported to emperor and dumpling.
